Ford Super Duty (1999-2016) :: 2007 F250 - Very Rough Idle When First Started / Engine Missing
I have a 2007 F250 4X4 6.0 diesel. When first started it idles extremely rough to a point it sounds like a old gas engine missing. But after it warms up for about 15 minutes it runs and idles like a new truck. I'm thinking it's the injectors if so is this something I can change/clean ....

2002 7.3 running rough.
This is my symptoms : On cold start ups engine runs rough. Idling it knocks worse than normal on the road she runs really rough. If I get on here she smooths out ( but still runs rough a bit) but normal driving at between 1200 -2000 rpm she runs so rough it shakes the whole truck. It will do this until she gets up to operating temp & then it goes away. The more she warms up the better she runs.
Once up to temp she will run perfectly. The colder it is outside the worse it is & the longer it takes for it to go away. I have replaced the valve cover gaskers and new harnesses, new glow plugs. Still same problems. I have AE and one time it gave me a #2 cylinder code. have not been able to repete this code. What to check next.

My v10 has a cold miss when i start it in the morning no matter what the temp. It misses until it gets up to operating temp.then it runs fine all day with a slight miss.
- Changed plugs,
- Changed pcv,
- Changed iacv,
- Cleaned map sensor,
- Changed tube to pcv,
No codes. Its running as if it had a carb and the choke is closed. No smoke, tach. idles between 750 down to about 500, until it warms up then tach. Stays steady.

I have an 2003 F250 7.3 Diesel 4wd. Yesterday I knew I was low on fuel but I don't think I ran out of diesel. My gauge was above the "E". 50 miles left on my overhead readout, but you never know. All of a sudden the truck misfires and is running very rough before it dies on me. I get it towed home.
Thinking that it possible I ran out of fuel and screwed up my fuel pump, I bought a new fuel pump and fuel filter, installed them and I have the same symptoms. I am guessing I lost my prime, who knows. I have 180,000 miles on it and haven't ever had engine problems.
Ford Super Duty (1999-2016) :: 2003 F250 5.4 4WD - Running Rough?
I bought it and changed the fuel filter and it was dirty. Then ran a tank of gas with seafoam and then with lucas fuel injector cleaner. Still nothing. It idles like its missing and as long as you are light on the pedal it revs up fine but if you're heavy on the throttle its. Its has no codes that's why I haven't replaced the coil packs and plugs but they have been ordered. I just thought there would be an engine code if any of the coils or plugs were bad. Looked for a vacuum leak but couldn't find any. The donut gasket on the pass side is bad would that cause it to run shifty with no code.

2008 F250 5.4L 150k. My truck has been driving pretty rough in low gears, rough idle, and today the check engine light came on then getting on the interstate the light started blinking. I ran the code it came back 0307,300,308,300. After doing some research on here, I've come to the conclusion to change out the coils on 7 & 8. Questions are, should I change plugs as well? And how important is it to keep all the boots (of all 8) the same color (brown or black)? And should I expect to change all the rest soon?

I have an 02 f250 V10 with a rough idle (90K Miles). It's not horrible but it's obviously not running perfect. Everything seems ok when I am up and driving, especially at freeway speeds. I recently noticed that if the truck is in park and I run the RPM's to 1500 or 2K and quickly let off the gas it will die. It never throws any codes. So far I have replaced the IAC Valve, fuel filter, O2 Sensors, PCV valve, cleaned the MAF sensor and replaced the air filter. Plugs and boots were replaced 5K miles ago. Fuel trim levels on both banks are running around -3.1 to positive 3.5 based on what the computer is telling me. Also according to the computer the vacuum sits steady around 25 at idle (+ or - .2). I don't have a manual vacuum gauge, just relying on the computer. I've also gone around to every plug and disconnected both the injector wire and the COP wire and they all seem to equally affect the idle as well as the fuel trim levels.

I have an 02 f250 5.4. I just did the intake manifold. I also changed the spark plugs and the valve cover gasket. Following this I drained the oil and filled it with fresh oil.
It started right up but it felt like the engine was really vibrating and running rough. The check engine light than came on. I don't have one of those tools to diagnose it.
What could be wrong?
Ford Super Duty (1999-2016) :: 2002 F250 V8 Running Rough - Code P1152
My truck has been doing this for a while now but it has progressively gotten worse from about three months ago when I went through some deep water. I don't believe it had to much to do with the water, I just think that the water is what didn't deal the situation and lead to the problem becoming more prevalent. But continuing, yesterday it got down into the high 20's and my engine started acting up (rumbling coughing, surging while at/leaving complete stops) and then it finally through a code for once and I head over to the neighborhood AutoZone expecting to get a lean code (because when the engine is acting up really badly I can unplug the fourth cylinder fuel injector without the engine acting any differently) but instead I received the p1152 (bank two lack of switching (rich)) code....
At this point I believe it is a faulty fuel pressure regulator, but without a good diagnostic obd2 reader or a fuel pressure gauge I'm not sure what to do. I'm currently in college, money is low, and I'm trying to take an accurate shot at the part that needs to be replaced so that I don't have to buy more than one part. Of course AutoZone says o2 sensor but I changed both about five months ago.. I've been chasing this diagnosis around for way too long now. (It's on a 2002 ford f250 5.4l super duty)

2005 F250 6.0L ... My truck is running really rough when the engine isn't all the way quite warmed up. once the truck is fully warmed up to normal running temp it runs good. I am getting four engine codes. P0672, P0673, P0674, P0676 These codes say 2,3,4, and 6 glow plugs have a open circuit. Can this be the cause of my problem?

I just bought this 99 f250 7.3 Powerstroke last week.. drove it all week fine, I car pool with a family member to work and asked his girlfriend to plug my truck in for me, well she didn't and it had stalled on the way home one morning but started up after cranking a few times i thought nothing of it. Drove it a little bit that day and it was fine, while I let it idle in my drive way as I prepared to go work it started running really rough then died. It took a long time to start again..now it's happening all the time. I changed the fuel filter and someones telling me there's air in the lines..

This is my first diesel but my 4th Ford truck. The truck currently has 4000 miles on it. My first incident started at 500 miles when my windshield gasket or lack/loss of silicone on the upper gasket decided to go. This caused a tornado in my cab at 6 am blowing coffee out of my cup and literally atomizing it all over myself pretty much LMFAO. It sounded like a helicopter attack at 40mph when it went. Ended up being towed to the dealer for repair. At around 2k miles the truck started too stink, like exhaust and coolant maybe. I'm thinking it's the DEF or the left overs from a regen cycle (newbie). At 4K miles, it's getting worse. The cab almost feels like deicing in the plane on the runway, nothing but fumes. It literally blows in through my HVAC vents straight into the cab. I'm glad I own the company because I'd be afraid of getting a drug test when I got too work. Instant red eyes. It is not as bad while driving but starts up again at red lights etc. It's a handful of times a week it does this. Things I've checked, water separator, 0 water in diesel. I've tried different gas stations and different DEF brands. Nothing makes it better or worse. I've read that I'm not alone, God speeds too us skunk trucks.

Ok just bought this truck ran fine. Put a sct tuner on that the truck came with and some how got the egr turned on. It had a egr delete so it was smoking and finally found it out that it had turned on but fixed it. Now we have another problem, it will start up and run fine and about 45 seconds it will start running rough and go into a limp mode. It will run rough and starts to die slowly and when it starts to die there is no throttle at all.

I changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?
