Ford F-150 - 1997-2003 :: Rough Idle / Sluggish On Takeoff / Blueish White Smoke
Jul 9, 2012
I have a 98 expedition with the 4.6l 4x4 and it has 158,000 on the dash had a new engine installed at 100,000 it started running rough and sluggish last week so I changed out the spark plugs and while changing the plug I notice oil on the threads of the two rear passenger side plugs. After the new plugs it was smoking pretty bad blueish white smoke. I figured it was the oil from around the threads that had leaked into the cyl.
The smoked cleared after 2 days and ran great for a week. Now its doing the same thing again real rough idle and and its extremely sluggish. I can put the pedal to the floor and she barely wants to move almost like the tranny is going out but the rough idle leads me to believe its and engine problem. I have the check engine light on but can't get any codes. I also tried checking for vacuum leaks by spraying either round the intake and vacuum lines and didn't notice any change in rpms so I'm guess the vacuum is fine.

I'm losing coolant have, excessive white smoke coming from the exhaust, and rough idle. Doesn't over heat or even try to overheat. The oil fill cap looks brownish white. It drives fine other than extremely rough idle. I know how to check a blown head gasket with the combustion gas test.
From what I've read blown head gaskets on 4.6 fords are fairly uncommon but a blown intake gasket is fairly common. How can I tell the difference?

99 Ford F-250 4x4 Ext Cab 287,000 miles. I know she is getting a little long in the tooth but this issue is new within the last month. It does seem to be better when it has been plugged in. On start up I smoke out the neighborhood. Blueish/White smoke, also sounds like it's missing on a couple injectors. Doesn't matter if you cycle the glowplugs a good long time. Glow plugs are 1 1/2 years old along with injector o rings. Only thing new is I changed from Rotella T-6 to Delo 5W40 Syn, but it was doing it before the switch as well. I tested my glowplugs relay and that is working fine. Could I have lost a UVCH? Fuel filter six months ago or so.

I just looked back and it has been since July 7th that my girl has been sitting in my shop. Well this past weekend I finally got her back together and started. It took a while to build pressure but she finally came to life..
While I am thrilled that she is running again i have low power before the boost kicks in and is idling rough with a blueish- white smoke coming out of the exhaust. Once i kick her a little she will get up and go but I've never had the smoke before.
I'm thinking maybe a bad injector???

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've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.

My 06 6.0 is blowing a fair amount of blueish, whitish smoke only on initial startup, then continues to blow smoke slightly for around 10 min until it's warmed up. It seems to be getting a little worse as time goes on, only on startup though. truck has no other issues otherwise, has an egr delete, and some old edge tuner. I don't think it's head gaskets, no other symptoms.

Last weekend, I was riding my Golf 2.0L when it started losing power, then a thick blueish white smoke started coming out from the engine all the way through the exhaust. Stopped the car on the side of the road and had it towed back home. I've looked for loss of any oil or coolant but the levels are ok. No mixed fluids from sight. I've had a check engine light for oxygen sensor for a year or so, but I've been told that would not be the problem. I started the car a few hours after it was towed home, it was now cool so the smoke wasn't as thick. The smoke doesn't smell like coolant fluid. I took out a spark plug and there was a bit of oil onto it too. My engine runs normally. People have been telling me to look for head gasket, valve cover gasket, engine head, etc. A week later, I still can't find what it could be.

My 2003 F150, 5.4L has been having some rough idle/misfires issues both at idle and under load.
I have fixed one big vacuum leak, replaced the PCV valve, new sparkplugs, seafoam and heet in the gas, replaced fuel filter, tested the fuel injector resistance. Coolant levels have not changed. The truck burns about a quart of oil every 1000 miles or so. The white exhaust is heavier than condensation, but it comes and goes. The rough idling comes and goes as well, and it usually happens under load and the CEL flashes.
The codes I get are random cylinders, po303, po308, po171, po174 were the most recent but there have been other cylinders as well. I clear the codes after each attempt to fix it and they come back different.
I notice that there is a small exhaust leak that drips water just behind the engine, and when I shut down the truck a lot of water will pour out of an area just behind the cab on the passenger side as well as out of the bottom of the muffler (small hole, looks drilled).
Usually the rough idle occurs after filling up the tank, but from different stations so I do not think it would be watery gas. I use Heet every fill up as well. Also, there is a sulfur smell after the rough idling occurs (catalytic converter?).

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...

We have a 1996 GMC Sierra 1500 Turbo Diesel and since yesterday, it's had a problem... When it warms up, it runs really rough and misses at idle. While it is doing this, white smoke spills from the exhaust. When we rev it to about 2000 rpm it runs smoothly. Sometimes at idle it misses bad enough to stall. Some say it could be the IP, EGR or injectors?

2004 f250 6.0, 173k miles. I just had the head studs done and a new head due to a crack in one head, I got it back 3 days ago and she was running great. I towed my landscape trailer yesterday full of mulch and only went about 5 miles with the load, after the job driving to another one I noticed it sounded like it was missing at idle with a small amount of white smoke. Drove it home let it sit overnight, started it up this morning and a cloud of white/ blue smoke and a horrible rough idle. Smoke does not stop.

Lately I have noticed a lot of blueish smoke coming from my exhaust at idle mostly while warming in the morning though it would do it if the truck idled for a few minutes. I took it to the dealer because I have fords ESP but the tech couldn't get the truck to smoke and wasn't getting any codes so he sent it back with a clean bill of health. After getting it back I noticed it smoking again so I picked up the egr valve kit pulled the valve and cleaned it as best I could and replaced the seals, that was last night. This morning it was blowing more smoke than it has before and has continued all day whether cold or warm. I just changed the oil last week and it's still full so it isn't burning any. Head gaskets were done along with studs last month, egr is obviously intact, cat is gone. I'm really at a loss for this, It's an 07 f350 scsb 6.0...

I just bought a 97 f150 4x4 4.6L v-8 and keep having problems. The check engine light came on saying that it is running too lean. The truck had been sitting for a while so I changed the air filter, maf, and pcv valve. After changing the pcv valve it is now blowing white smoke. What can be causing this to happen?

I have an 01 f-150 4.6 triton and it now blows a sometimes pretty big ploom of white smoke at start up. Sometimes it smokes for a while after that and sometimes not. It runs smooth and strong but I have no clue what to do...

I have a '98 Expedition with 170k, 4WD, 5.4 and auto trans.
I drove me truck home about 15 miles and sat idled for 15 minutes while on the phone. The truck started running rough all of a sudden and then died. I tried to restart it and would crank over, but not ignite. I thought fuel pump, grabbed a can of starting fluid and eventually fired up, but was huffing white smoke. After about 3 minutes, it sat there and purred. No problem, right?....
I dropped it in reverse to back into the driveway, when I put it in drive.....nothing, no forward gears now..? It will start up and run now, but still no forward gears. I have a leaky heater core, but rarely have to add water......and no milkshake in the oil.

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?

I have a 7.3 that's running rough. Started it the other day it ran alright but started blowing white smoke. Bought a oil and fuel additive i was going to run through it. Came a few days later, it stated up and was real loud and sounding like it was loping. It blew a good amount of white smoke, but it just smelt like real heavy diesel. Now i can only turn it over and it won't start.

The truck is a 98 4.6l with 188,000 miles on it and yesterday i was driving up over a pretty steep grade hill, i was going about 55 and turning maybe 2800 rpms at the top a big cloud of white smoke came out (either tailpipe or just out of motor on hot pipes)and also some in the cab. It didn't run any different though so I kept driving about 3 mile and stopped where i could take a look and and saw fresh oil around the starter area running down where the motor meets the tranny. I checked the oil and it was at a good level and also not milky. I checked level again today and it seems well and there is no drops of oil on the ground i ran it home about ten mi and it runs good. What could have happened?
