Ford 7.3L Power Stroke (1999-2003) :: Six CEL Codes / Stall Out At Times / Shutters Or Pops Between 1800 - 2500 RPMs


Jun 23, 2017

I have a 1999 Ford F-350. I have six codes from my truck. The codes are P0237 P1119 P1690 P0500 P0603 P0344. My truck runs, but likes to stall out on me for no reasons at times. The other problem I am having is between 1,800-2,500 rpms, she shutters or pops.

Ford 7.3L Power Stroke (1999-2003) :: 2000 Excursion - Shutters When Cold

Truck is a 2000 7.3 PSD Exursion, 300k miles, automatic. Does this when cold, I let warm up for 5 minutes before this happened as its been doing it. Going to plug in tonight, was about 40-50 degrees out.

What is causing this shutter? Injectors? After I get off my dirt road to street it runs fine, also notice the ebpv. Seems to do shutter most when reversing.

Ford 6.7L Power Stroke Diesel :: Buzzing Noise When Accelerate Upwards To 1800 RPMs

[URL] ....

Ratchet buzz noise my truck makes. Is not present until motor warms up. Noise is not present as much at idle but when you accelerate upwards to 1800 RPMs it makes such an obnoxious buzzing noise its embarrassing. Noise seems to come from top center area of motor.....

Ford 7.3L Power Stroke (1999-2003) :: Running Sluggish In 1200 - 1800 RPM Range Intermittently

I am still trying to debug my 7.3 running sluggish in the 1200-1800 rpm range. The problem is intermittent. I checked the wiring harness under the valve covers to verify they are plugged in and there are no opens in the circuit. I replaced the crankshaft position sensor and the high pressure oil sensor.

This will run fine one time and a few miles down the road it will chug and smoke out the exhaust until I either get into the accelerator or back off and re press the accelerator. Again, it does it intermittently hot or cold.

I ran both a cylinder contribution test and perdels with a Snap On Verus. The cct passes everytime. The perdels have a couple of cylinders 5-6 and 8 fluctuate between 0 and 1.80% with #8 up to 2.5%.

My question is. Do the cylinders in the test correspond to the actual cylinders in the engine? Reason I am asking is the Verus does not follow the firing order on a gas engine. The cct is in order of 1-8 and I have to correlate the cct order to the firing order. Found this out the hard way when I had a bat cop on a 5.4 and replaced it only to have the same cylinder still show not firing.

I got out the graph leads and tested the cylinder and pulled the injector thinking it was bad. Everything showed good but the cct still showed it not firing. I had to unplug each coil and watch the cct to determine what the true cylinder in the test was. It turned out to mimic the firing order so I am asking out of concern that cylinder 3 in the perdels is really cylinder 3 or a different cylinder.

Btw, the perdels all show 0% if the transmission is in drive. I would have thought that a load on the engine would have showed higher perdel percentages with a load on it.

Ford 7.3L Power Stroke (1999-2003) :: Trans Slipping On 25hp Tune Up High In RPM Band And Shutters When Up Shifting

My excursion's trans is slipping on the 25hp tune up high in the RPM band and shutters when up shifting. I have dropped to stock most of the time, but I know i am on borrowed time.

I had a JW trans in my e99, and there is no question on the durability and performance of the transmission. The price has gone up a lot, but that's maybe not the big issue.

I live in the mountains and spend a lot of time pulling and just driving in that 40 to 60 mph range over mountain passes. That is basically where I spend ALL of my time.

The distance between 3rd and 4th is driving me CRAZY! I have researched everything from swapping to a manual, to PCS controllers, to trying 4.11 gears, to overdrive units.

Swapping Manual: ZF6 is the obvious candidate, but I have read the swap is not probably something I have the skills or tools to do. I have also read that the performance of the ZF6 is sub par. But it seems like it would give me my 3.5 gear that I am looking for.

PCS Controller: Looks cool for a way to have control besides using the tree shift. Maybe a compromise on not swapping in a manual.

4.11 Gears: I get pretty excited thinking about the low end torque etc. I go off road almost every week, and like I said, I hardly go over 75 mph. But once in a while I do. Right now, the truck turns about 2300- 2500 rpm at interstate cruising speed. Looking for 4.10s rpm in that range to compare? Also, how bad of a fuel economy hit would I take? What is the cruising rpm of 4.10's between 60 and 65 mph, or in general what is the rpm change?

Overdrive Unit: I have always been interested in more gears, but I read about someone who installed one behind a 7.3 and didn't have they great of results. To the point where he said it wasn't worth it.

Ford 7.3L Power Stroke (1999-2003) :: Black Smoke - Little Power - No Boost Until 2500 Rpm?

Short version is that I just did the EBPV delete with new pedestal and turbo exhaust outlet and put a new turbo middle cartridge in as mine had blown a seal and possibly broken the shaft. Once I got it all put together, I took it for a test drive and it was building 20PSI like it used to but I didn't have the accumulator and turbo mated up fully so I had a leak there.

I corrected that and now don't get any boost until I get to about 2500RPM and then it only builds to about 10PSI. I've double and triple checked all my connections, boots, etc. and everything is tight on the intake, intercooler, up-pipes and collector, exhaust and the spider, I can't see or feel any problems there. I tried disconnecting the MAP sensor and it might be a little better but not even close to normal.

Tried disconnecting the red line from the wastegate and plugging it with no difference. I'm stuck, and frustrated. I do have AE, watching the MGP looks like the MAP sensor is working. I feel like I'm overlooking something simple but I just can't figure out what it is...

Ford 6.0L Power Stroke Diesel :: 2006 - Idle Down And Won't Get Above 2300 - 2500 RPMs?

I bought a 2006 F-350 4WD Lariat SRW with a little over 200,000 miles on it. The truck seems to run perfectly, except when pulling a load (9,000-10,000 lbs) down the interstate/highway. Sometimes, when pulling above 65-70 mph for an extended period of time (45 minutes to an hour) the truck will all of a sudden idle down and won't get above 2300-2500 RPMs (even if you put it in neutral and floor it). It's not enough to shut it down, but it won't let the truck accelerate as fast as normal. Killing the truck and cranking it back makes it go back to running normal for a little while, but the periods of it acting up get shorter after each killing and restarting. I took it to the Ford place while it was acting up, and they thought it was a turbo problem. They cleaned the turbo and said everything looked fine, but the same problem arose after leaving the shop. They've been stumped at 3 different Ford shops, but one said there's a 95% chance a new turbo would fix the problem. What might be wrong?

Ford 7.3L Power Stroke (1999-2003) :: F250 - Code P1211 - Service Engine Light Pops Up Going Steep Hill

I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.

Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.

Ford 7.3L Power Stroke (1999-2003) :: High Frequency Squeal When RPM Passed 2300 - 2500

Anytime I run the RPM passed 2300-2500 I get this high frequency squeal. I don't seam to lose any performance, but very annoying. Is this the turbo having troubles. It's directly related to the RPM'S. Other that that, the truck runs great....

Ford Super Duty (1999-2016) :: 1999 F350 V10 - Loss Of Power / No Acceleration Over 2500 RPMs

Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.

Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.

If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal

If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.

Ford 7.3L Power Stroke (1999-2003) :: F250 Stall After Starting And Running Fine

I have a 1995 f-250 7.3 liter diesel engine. Truck starts fine and runs good for a while and then it will stall. I pull over and after a couple of attempts it will start and run fine for a while. I have changed the fuel filter and put fresh fuel in but it still stalls.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss And Almost Shut Down At Random Times

I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.

Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Occasional Rough Running / Stumble And Even Stall

A bit about my truck : 2001 F250 CC SB 4x4 175k miles
Wicked wheel, 6637 filter, DP tuner, Summit 5" exhaust, pressure regulator somewhere in the boost circuit to fool the computer a bit....

Every few times I drive the truck it will stumble and maybe even stall. The issue feels something like a CPS problem, although I've swapped out a few CPS to see if I by chance had a bad one in the engine as well as a bad one in the glove box. No changes. I was driving home from work one afternoon and it was running particularly bad. I stopped off at a local garage (who doesn't work on diesels and was reluctant to plug in....but did because he's a nice guy).

He plugged in with his snap-on tool and came up with P0603 and P1211. The P0603 seems to be nearly inevitable with a tuner. Check P1211 sounds like it could be an issue with a number of things, but I tried to attack the free and cheap issues first. I dropped my tank and had a look inside. I was hoping to find a squirrel wrapped around the sending unit, but there was a disappointingly small amount of crud. I cleaned it up and put it back in, then changed my fuel filter. No improvements.

So I decided to get with the program and buy AutoEnginuity. Got it. Even did some reading in class and did the initial homework assignment on page 2 or 3. Seems like the best thing to do it hook up, set up some parameters to monitor, and drive around recording until the problem happens. But.........what parameters do I want to monitor? I don't want to overtax the OBDII bus with too many requests such that my data looks like crap.

A few other things............ In the last year I swapped out the valve-cover gaskets & harnesses with an all-in-one molded setup. About a month back I replaced the exhaust back pressure sensor and tube.

Ford 7.3L Power Stroke (1999-2003) :: Brakes Sometimes Soft Other Times Firm

So the other day I had someone change lanes and slam on the binders right in front of me which caused me to slam on mine. Luckily no one got hit. Now my brakes feel different. Sometimes the pedal feels nice a firm other times it pushes in 2-3" before starting to brake. The fluid level has not changed in the resevoir and the hydroboost appears to be working fine. The power steering is still operating as before. I have checked the calipers and none are leaking.

My suspect is the master cylinder but was wondering if the symptoms are common with the master cylinder failing? I'm thinking internal o-ring has failed due to the near accident event. I'm going to do power steering flush just because I never have. Is there anything that would display these symptoms that I could check before buying the master cylinder?

Ford 6.0L Power Stroke Diesel :: 2006 E350 Truck Started To Stall As RPMs Dropped

New here but long time lurker. I have a 2006 e350 with 6.0, bought it from a friend not long ago. The work that has been done to it the last 50,000 miles is as follows.. New hpop, all new injectors, egr delete, sct tuner, stand pipes and dummy plugs. I had it for a week and would get a no start hot once in a while. This issue had become worse and the truck started to stall as the RPMs dropped. Reading here i replaced crank sensor and the stalling stopped but the no start hot continued. I took it to a local diesel repair shop and they did the following..

Use a test ipr (no change), replaced ipr pigtail (was cracked) air test (leak under pass valve cover) replaced stand pipes and dummy plugs on this side. They said no leaks and I was good. Truck worked as its supposed to for 1 day and the no start hot issue reared its head again. Took it back and now they say the hpop is bad. The pump that was put in about 50,000 miles ago was a bostech? do these go out? Sangauge reads good ficm, but seams ipr doesn't climb that quick.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - No Acceleration / Truck Jolted Forward A Few Times?

My 2002 f350 7.3 was given to me in July of this past year. I was 15 at the time and I was told that it was hydrolocked. Funny enough this is where I came to learn how to fix it, and this is the first time I have had to ask a question . I pulled both heads and replaced all 8 injector cups, I also had the heads re surfaced and had 7 injectors rebuilt and 1 replaced. I got it on the road in February around the 20th and since then I have put about 300 miles on it. Today I stopped at a red light and made a left turn and as I went to accelerate the truck jolted forward a few times and it felt like a tire was going to fall off while accelerating(only to 30mph). I pulled into a driveway to check all the tires, then I turned around and my foot was hard to the floor and the truck wouldn't go over 15. Diddn't smoke when it first happened, but after getting it off of a flatbed I turned it around and it hardly had enough power to get up my driveway. And I noticed it was pushing a steady stream of white smoke, the oil is clean and the oil cap doesn't get blown off at idle when I set it upside down on the valve cover.

My 2011 F250 6.7 started throwing multiple codes a couple of weeks ago. I cleared them but they all came back at the same time. What these are pointing to? I'm assuming they're all related?

It throws 9 codes total, the three listed above, 3 times each.

Ford 7.3L Power Stroke (1999-2003) :: Idle Roughly - No Power - Got Codes P1280 And P1316?

Started my truck yesterday and drove about 1/4 of mile and all of a sudden I lost all power but was lucky enough to creep back home. Had a friend put it on a scanner and it spit out P1280 and P1316 codes. My truck will start and idle rough but has no throttle response and no power. I changed out the CPS and ICP and the problem still exists. I got an infrared thermometer and checked the heat coming off each manifold and the driver side was reading about 200 while the passenger side was reading about 75 while at idle. Pulled valve pan cover off the passenger side to check and see if the harness came loose and everything looked fine. So my question is do you think this could lead to a bad IDM?
