Ford 7.3L Power Stroke (1999-2003) :: Missing At Idle - Power Loss At 50 MPH - White Smoke From Tailpipe
Jun 1, 2015
My 02 excursion is missing at idle and jars the whole truck around going approx 50mph feels like good amount of power loss but still pushing 30psi boost, just got autoenginuity all injectors buzz fine on the test, contribution test show balance fault in cylinders 1&8, should I look for o-rings to be bad, uvch, cups cracked or what ----- turbo fine, hpop great condition, new IPR, new fuel pump and hutch mod, about. 250k miles on truck nothing else major showed up on ae.

I have a 2001 7.3 that almost has everything practically brand new... new hpop, water pump, uvch, gpr, glow plugs, icp sensor, ipr sensor, cps and new turbo pedestal that was leaking oil, well now my truck has a cold start to where it has to be plugged in to start and when it finally does it smokes white pretty bad, misses and sounds like it's jumping around under the hood up until it warms up and revs fine with less white smoke but still a miss!!
Compression on test has been done, and good, fuel pressure is good, but the buzz test when cold shows 123457 muffled and quite and when the truck is warm only 3 and 4 are still muffled and quite? Injectors sticking?? Or just need New injectors!

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

Recently I have had many problems with my 2000 7.3l .... The one I cant get rid of is the p1316 code. I have changed out the uvc harness and gasket with new ones, then removed valve cover's to double check connections again and they are fine. I am getting white smoke and the truck misses. I do not have a advanced reader for the codes just using my edge programmer. I have also disconnected the battery and cleared the code but it comes right back.

I have a Tymar intake, magnaflow exhaust, a DP Tuner and I have Rosewood Diesel injectors.
I had a bad oil leak recently and it seemed to be coming from the turbo area so I changed all the o rings back there and deleted the EBPV system (I cut out the butterfly and welded the holes shut, cut the part of the pedestal that held the actuator because it looked like it was leaking and welded the oil holes in the pedestal that fed it. I left the actual EBPV sender in the pedestal and kept it connected to the harness)
After all that was done I checked the oil and it was low but still on the dipstick so I drove it to the local parts place to get some more oil, about 2 miles, because I wanted to check for leaks. It was not happy, ICP low code came up it was sputtering and jerking when stopped at a light. I got to the store and parked it, it took about 3 litres of oil and seemed to run pretty good after that.
But on the way home I noticed a bunch of white smoke, I figured maybe an injector was stuck. I started it a little later and no white smoke in the driveway so I thought maybe it had gotten lubed enough and had sorted itself out. That was a few days ago.
Today I started it and let it idle in the driveway for about 15 mins and no white smoke, I wanted to get it up to speed a little so I took it to do an errand that was about 10 miles away, lots of lights and a bit of highway. It would run fine while going at speed but as I would slow down for a light the ICP would go down to around 600psi and the white smoke would start, as sitting idling a huge cloud of white smoke would form (yes, I was that guy), once I could take off and get it running a bit harder it would go away again.
I am assuming that I have a stuck injector (or cracked), I have no oil in my degas bottle and it doesn't look like it is fuller than before. Seems like I may have used more fuel than I should have, but pretty hard to tell just from the fuel gauge.
I have tried a buzz test and they all sound the same, tried a Compression Contribution test, no codes from that.
How can I locate a stuck injector? If that's what it is?

Early 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild

I have an 07 6.0 with 400,000 miles. Has been a great truck with no major problems. Before I started the work I had 3 bad injectors, running rough and the oil/ coolant temp just outside of 15 degrees. So I tour her down and replaced head gaskets, installed arp studs,all new injectors,all new glow plugs and new oil cooler. Ran great for a couple days. Then when driving to work lost power on and off for a few miles then completely gone could only go 10 miles an hour. I checked codes and there was the under boost code witch has been on there for a while and I forget the other code but it was for the ipr valve so I replaced the valve and right after still the same but that code went away and the p0470 popped up. So I cleaned out the ep sensor tube and replaced the valve. After several miles she now runs great but now I'm getting a little puff of white smoke when I take off and not every time and mainly when I take off some what quick. All codes are gone expect the under boost. I have an egr delete already.

I am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?

I have a 7.3 Excursion, 234K Miles, 4R100 Transmission. Today I was in a rush to take one of our dogs to the vet, when I hit overdrive going up a hill, it almost sounded like a clicking noise and I was steadily losing power. I came to a stop sign and put it in park and it started to develop a constant lope that was rough. Whenever I would step on the gas it would put out white smoke which it has never done before. I was able to take it a couple miles before it did the same thing except this time it shut itself off.
Recently I have been having transmission issues as it feels im losing first gear. A while back I noticed it would idle slightly in park every now and then. A couple days before this happened, I came to a stop and my truck started loping slightly and first gear IN DRIVE felt very very weak. I have recently replaced the cam position sensor as well as the ICP sensor. I'm at a loss, I plan to do a ZF6 transmission swap very soon and this is only making me panic even more.
I never dog the truck, take it mudding, etc. Oil is changed every 3-4,000 miles. I did however get it scanned a while back and I believe two codes came up for two pistons, also did an injector buzz test and they all sounded strong.

I was having an issue with coolant loss and white smoke from tailpipe. Was told it was likely intake leak vs headgaskets. Changed intake gaskets, fixed the issue for a day then it started just dumping coolant from every available place in the exhaust system. Was draining a full collant bottle in about 2 minutes. Was also checking for exhaust in the coolant with the tube and blue liquid which it stayed blue. Had previously done a degas pressure test and it passed. The only test I hadn't performed was compression test which all the cylinders output was lowest 160 to the highest about 185. Did not perform a wet compression test as I was mainly looking for base compression and consistency.
Not sure what healthy is on these vehicles but considering they were all running pretty close I call it good. Also it idles just as smooth. Pulled intake a 2nd time and rechecked my previous work. Everything looked fine so I put it back together. Ran smoke free for about 50 miles now I'm back to smoke after it sits a bit but it clears up after a short drive. What am I missing? I will note that I had a small coolant leak from drivers side rear of engine that I noticed while it was parked in the shop. I'm assuming that would be the oil cooler? But oil is clean so it's not mixing. What other avenues on these engines can coolant make it into the exhaust? Drives perfect with no power loss.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

Just picked up a 99 F250 7.3 Stroker, it had sat for two years in a warehouse, the truck had just had reman injectors put in right before it was parked. We fired it up, and it was missing, and smoking a lot (light blue, almost white) I checked the oil filler cap, and no water on it, after it ran for a while, it stopped. Shut it down, went and got my trailer ready to load the truck, fired it up, and no smoke to speak of, by the time I got it to my trailer, still no smoke.
I revved it against the governor a few times, hoping to clear the miss (figured may have been trash, or a sticky injector from sitting so long) It is turned up pretty good, as it came with a Superchip Super Tuner. It seems to hit on all eight above 2500 RPM or so. Brought it home, and took it out on the road, it seems to only miss under 2500 RPM or so. I took of from a dead stop, then got on it hard at about 15 to 20 MPH, it took of nice, then all of a sudden, the tach started climbing like the trans was slipping, looked in the mirror, and the tires were smoking, guess they broke loose when the boost came in!
I let it idle and warm up for a good half hour and noticed a lot of pure white smoke coming from the exhaust, went back to it and it was steam, I took the oil filler cap off, and there was a lot of steam coming out of there, pulled the dipstick, more steam, I then noticed the degas bottle was low, I topped it off, and got in the truck, and revved it a few times, then held it at 2500 RPM for about a minute, It started blowing water out from under the degas bottle cap. I called the guy I got it from, and he did NOT put new injector sleeves in when he did the injectors, I don't see any oil in the water, but there is water getting on the oil filler cap now! Does it sound like a head gasket, or an injector sleeve?

My 2001 7.3 is smoking only when barely on the gas. New fuel filter. Don't know if its possible injector going bad or what? Smoke is white not black.

I have long been having troubles with white smoke at startup, even when its 90 degrees out. Long story short I've got new glowplugs, GPR, UVCHs, valve cover gaskets, injectors, turbo, valve seals, valve springs, and HPOP all within the last year. Most of those parts were needed, some maybe not so much. After installing injectors things started getting worse, whether they're related or not I'm not sure yet. I pulled passenger side valve cover off again in an attempt to figure something out and heard this coming out of the intake spider.
[URL].....
The strange thing is it goes away when it warms up. I should also note the reason I started with the passenger side is because I did a compression test and this side had the lowest readings, with #5 being 270 psi. I disconnected each injector one at a time on the passenger side to see if it made a difference while running but didn't really notice a difference. Am I looking at a motor rebuild, or at the very least a head removal?

my 2000 f350 7.3 is acting strange lately. Its got 252k and is all stock other than exhaust,intake,ww2. It smokes white every random once in a while for some reason. At start up it wont though. If i get on it every once in a while it will smoke white then go to back to black. Im not consuming coolant, and the oil looks fine, no residue on the oil cap and its not puffing out the oil cap either. Other than that its running great just dont know why it goes white every so often.

When my 99.5 SD is cold ( 50-60 f) it smokes a lot of white horrible smelling smoke for the first 2-4 minutes. If plugged in the block heater it doesn't do it. Also when cold, when you accelerate the SES light comes on until you let off on the throttle then it goes off. Even going 10mph in low rpm? Once engine is up to temp it doesn't do it anymore. It seems to run fine otherwise. I do have 2, 700 CCA Napa batteries that are from 2011 which I plan on replacing next month with Motorcraft Maxx 850 CCA.
I have replaced the UVCH, CPS, Fresh Oil and put additives in my fuel. I have even disconnected my DP Tuner F5 and it still does it. I have AE with ford bundle and it seems like my HPOP seems to be working fine as well as buzz test and glow plug. Could it be an injector ( I have stage1 casserly from full force)? What about a sensor not working? It has always smoked since I have had it ( about 3 years) but the SES light issue has only been happening since my IDM was replaced and I had a mechanic work on it.

For the past few days I noticed my truck would be really rough to start and a lot of white smoke. but once it ran for a minute or less it would be fine. Today when I got home I popped the hood and was looking for anything and noticed my degas bottle had this weird fluid inside on top of the coolant? So I popped the cap off and smelt it and its fuel. Of course this would happen to me. Now I'm not going to lie I have beat on it a few times this week but nothing so so serious.
Could this be contributing to it? Could it be a head gasket? now being a diesel mechanic I doubt its a head gasket simply because there is no oil mixing. I am praying its nothing too major. Once I have the narrowed down to what it could be ill see if its something I could tackle or if the stealership has to do it, which I am not looking forward to. I'd rather be down a truck for a little bit and save a boat load of cash.

SO, I've owned a 92 f250 7.3 for 10 years and it's got over 340k miles on it. Well, she is getting tired so I'm debating replacing the truck with a SLIGHTLY newer model.
I've found a truck that is a 99 7.3 powerstroke with a 6 speed manual and 260k miles. Knowing these engines I feel this truck has at least another 100k in it if the thing was somewhat taken care of. The issue is that the fella that has it for sale says it ran great for years and one day started blowing white smoke while driving. Other than this new issue it runs fine.
So my question is, what could be the issues causing the white smoke? I always thought white meant unburned diesel or maybe antifreeze. Head gasket comes to mind but it's not something I've ever dealt with.
I like that he parked it when it started having issues. Sounds like someone who doesn't completely trash their vehicles. Too high given the condition? Truck looks and sounds pretty good aside from the smoke, pretty reasonable condition.

My 1995 Toyota Tacoma has 217, 000 miles and was running great. The other day it started to make a whine when making tight turns. I had just climbed a hill and was backing it into a parking spot when the steering became hard to turn and a plume of white smoke began coming out of my exhaust. There was no smoke under the hood. I had it home immediately. I'm hoping it will not become a new planter box in my back yard.

So my truck a stock 2000 7.3 started smoking when I would start it up in the morning... figured it was a glow plug issue. Checked the relay it was good, checked the glow plugs found 2 were bad replaced them.
Thought I was done, well I started it up and took it for a drive. still smoked... thought no big deal I know some oil leaked into the cylinders doing the glow plugs.
Then it started rattling like a lift went out, no more smoke though because the truck was warm... shut it off at my buddies. Limped it "it actually still drives ok" 5 miles home.
From my research it sounds like an injector. I have tried a buzz test and they all sound the same.

I just replaced my up pipes, turbo pedestal O-ring, ICP, IPR, New O-rings in all my injectors and torqued to spec, new glow plugs, glow plug relay, oil loom wiring harness, new O-rings on oil cooler, oil filter, oil, and antifreeze. I have tried and tried on upwards of 75 or so time to get it to turn over. A little white smoke came out and it sounded like it wanted to fire up, but only a few times.
I have good batteries and a charger on it, 3-4 tries in 5-10 second bursts or longer if it doesn't lose power every 30 -hr. oil is in HPOP too. just found out my block heater is dead, but I shouldn't need it now. Tach moves a little when I crank it but only when my oil pressure gauge hits half way and that about the time it wants to start and starts white smoking.
