Ford 7.3L Power Stroke (1999-2003) :: 2002 - Runs Rough And Stalls After Half Mile?
Here's what I'm dealing with. Took the truck on a 1500 mile trip with no issues. Got home and started it the next morning and it started right up. 1/2 mile from home it starts to run rough and wants to die. It does this for a few minutes and then perks back up and runs fine for however long the trip is. It will always re fire and have no issues. Every morning it's the same game as described above. Within 1/2 from home it's doing this. Seems to be fuel delivery related, but why would it start after sitting overnight, and then after its little fit, run without an issue?
No codes in computer.
Ford 7.3L Power Stroke (1999-2003) :: After Start Up Engine Throws Wait To Start Light / Runs Real Rough And Just Shuts Off
My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.

So I had a reman 7.3 and 4r100 dropped in my 03 excursion.. since then the engine fires up every single time.. ONLY when the truck sits for 2 days i have this issue where the truck fires right up, runs for 4 or 5 seconds then stalls out.. It starts back up on first try and idles rough 10 seconds then it runs great.. If it only sits 1 day i dont have the issue if it sits 1.5 days it will try to stall out and catches itself from stall out and doesn't stall about 3/4 of the time. The mechanic who is a reputable diesel mechanic cant figure it out.. they called swamps and they also were unsure.

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

I have my 2002 Ford F250 Powerstroke. 175,000 original miles by me and only me. SCT, MBRP, Howes or Stanandyne almost always. Runs like new. It starts rough if I don't plug it in. Even on 50 degree days. Then it levels off and runs perfectly. If I plug the truck in I can drive off immediately with perfect operation of motor. I just went 1500 miles. Pulling a car hauler with car. NP at all.
New Glow Plugs, GPR "Yes it works", IPR, New Harness, Buzz Test shows it's fine, New #8 injector last year, New O rings HPOP. My buddy who is a PStroke guy said this trucks runs too perfect for it to be injectors. He recommends seals for the injectors. What does this mean. Or what else can it be. Where should I start.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Truck Runs Rough When Cold
I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?

Truck has a rough idle and finally just stalls out. I replace the under valve cover wiring harness and put in new glow plugs. With valve covers still off I started the truck in the issue still persist. I went ahead and unplugged each injector and each time the motor had a hick up .
What am I pulling apart and replacing next?

2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.
I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.
I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.
Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light Constant On
I bought my 2000 7.3L Ex as salvage back in 2005. It had been through a driver side rollover and the seller had restored it. We lived in North Idaho then. But I remember I always had an issue with the check engine light being on. I don't remember what the codes said, but many mechanics read them and determined that nothing was wrong. Many surmised that someone had put a high performance chip in the computer and that was what was causing the check engine light to come on. All of them reset the computer and every time it would come back on. Should I replace the computer?

1999 f250 7.3 101k California truck ... Scanned it said #1 glow plug did not clear the code. But now the check engine light is off again...
Questions : Harness issue ? Glow plug bad at 100k ? Glow plug controller ?
Start at glow plug work way back to GP CM or in reverse ?
Replacement Do all 8 or just the bank of 4 ?
Thoughts on replacement brands
Accurate diesel glow plug replacement kits any good, will they last ?
Or go factory glow plugs
What about Felpro gaskets
I heard about another brand of GP CM
Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light While Towing
2001 F350 290,000 no mods other than 6637, 2WD
Towed our new to us RV home last, only 15 miles from the dealer and yes its a big 5th for my truck at 12,000lbs. Anyhow, about 2 mins from home as I'm pulling off the freeway I got a SES light come up, then it disappeared. I checked codes this morning using forscan and nothing shows to indicate what it may be.
I was wondering if the transmission is getting hot if it throws an SES? It was only a short trip, but I have no real idea of the condition of the trans as the truck is new to us too - fluid looks and smells good.
Only new code is an ABS one c1229, c1233, C1234. I had 2 of them before - think the 1229 is the new one.

2003 7.3 excursion.. The truck starts every time revs up and idles about 3 seconds then the rpms drop and it tries to stall out catches itself then revs backup and idles rough similar to if you have got air in the fuel lines from changing the fuel filter.. About 1 in five times the truck will stall out and it starts and immediately and idles rough but the rpms and everything runs at speed and rpms don't drop again! This is a reman engine/transmission recently installed.. The mechanic who installed it was unable to figure the problem out.

So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong. Any way to check what's wrong myself?
Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...
Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light Briefly On After HPOP Rebuild
Now that I have been driving for a while I kept seeing this light come on/off and I did a video below - I don't generally flash my lights so don't think I am aggressive - but I wanted to make sure to capture the video and the light coming on.
I was thinking valve cover connection the 50 cent mod - and maybe it's all coincidental - but I did have to pressure wash the troph where the oil collects and maybe something else got knocked loose.

Ford 7.3L Power Stroke (1999-2003) :: No Throttle - Check Engine Light Came On When Pedal Is Depressed
I have a 2002 F250 4x4 Powerstroke with Automatic. I have been having off and on issues for months with the throttle going dead. This only happens when I start it, if it works when started it will continue working until a different start session.
I have replaced the pedal several times before learning how to check its output with a meter and am quite sure that is not my issue at this time. However, when the pedal is depressed the check engine light lites up and nothing happens.
I am thinking it must be the computer itself, but was told there is another sensor or module under the hood that could cause the issue also which is several hundred dollars to replace as would be the computer.
Is there a way to test the computer, and what is this other module/sensor if it exists that could be the issue? Unhooking and rehooking the battery to reset the computer is no longer working to buy me a few more weeks, is there a simple way to reset the computer to try?
I love this truck when the throttle works but I am getting tired of paying on a truck while having to borrow a vehicle to drive to work.
