Ford Super Duty (1999-2016) :: 2004 - Running Rough Both At Idle And Driving - Truck Shakes A Lot At Lower RPMs

I have a 2004 SD with 5.4 that is running pretty rough both at idle and driving. Truck shakes a lot at lower rpms. I have a scan tool and had a misfire on cylinder 4 so I replaced the coil and the plug. Also replaced the idle air control valve. Plan on replacing O2 B1 S2. (One of my codes) even after replacing the coil and plug I'm still getting misfire detected from cylinder 4??? Other codes I had were misfire detected on he first 1000 revolutions. That hasn't come back though.

Lately my 2001 F250 5.4 engine is running rough when I am accelerating or keeping it certain speed. It feels like it is jerking. Like if the truck lost power for a second. This will go on for few minutes. Where to start to trouble shoot.

Ford Super Duty (1999-2016) :: V10 Running Rough / Engine Ran Fine Until Battery Died

2002 F-250 SD V10 Auto Trans 140K miles.....

Engine ran fine until battery died. Vehicle then sat from Nov to May with no battery in it. On start up now after install of new battery, engine initially surged at idle and seemed to miss (run rough) in gear/under load. No CEL or codes. After a single short drive idle and running under load seemed to have improved a bit, but not yet back to what I would call normal.

QUESTIONS:

Is this simply a matter of the computer having to relearn after battery disconnect?
Will driving restore things back to where they were/should be?
How much driving/How far?

Ford Super Duty (1999-2016) :: 2002 F250 - Engine Running Rough And Vibrating

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) :: Running Rough - Check Engine Light Came On And Got Codes P0171 And P0174

My 1999 F350 SD V10 that would crank but not start. I ended up checking numerous things because before it decided to truly stop running, it would run rough for a time and then be fine. The check Engine Light came on and I got the codes P0171 & P0174. Well, I bought MAF Cleaner and took the air cleaner housing off, disassembled it and thoroughly cleaned the sensor and replaced the air cleaner. I continued to get those same error codes, but before I could go any further, the truck totally died. It sat for nearly 2 months with the bed in the air as I had decided to lift the bed to check the fuel pump vs. drop the tank.

Fast forward a bit and I have since replaced the fuel pump and put $40 of Premium Gas along with Royal Purple Fuel Treatment in the tank because I figured things got stirred up and could use a bit of cleaning. I do not drive much, and during the first few trips, it ran perfectly. Then today, it started again with the rough running and trying to die if I let it idle. If I pushed on the gas, it would completely smooth out. If this were a carbureted engine, I would think the low idle was set too low, but since it is not, I am guessing it is one or more of the sensor/s that is/are causing the issue.

I am disabled and can’t play parts swap until I hit on the right part, so I was hoping that I might get some guidance here to narrow things down to the most probably causes so that I won’t go broke changing things until I hit the “right one”. The truck has 153,000 miles on it and I had bought it from a retired couple who used it to pull their 5th wheel travel trailer, so it had mostly highway miles on it. It was immaculate when I bought it and ran perfectly, needing only normal maintenance (oil changes, etc.) over the past 12 years that I have owned it. In those 12 years, I have put about 60,000 miles on it.

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?

Im having an issue with my 2000 f250 7.3 diesel. 4x4. The od light is flashing and the tranny is kind of jerky when it shifts. Also my truck won't go into 4 low.

Ford Super Duty (1999-2016) :: F250 Misfires But Running Very Rough

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) :: Running Rough - Chugging Just Off Idle?

V-10 running rough at idle, chugging. a problem has developed with my 2004 E-350 V- 10 after having a new fuel filter installed and the induction service done . Picked it up from a local shop and it was running rough after bringing it in when running great! I figured maybe it fouled a plug or something so I drove it home but it didn't improve so I brought it back and had new plugs installed. It is still running rough and wanting to almost stall when accelerating from a stop and the shop cant figure it out , not showing any codes.

I'm thinking maybe they caused some type of vacuum leak that is so far undetected. The killer is it came to the shop running great !!

No other problems with the vehicle, I drive it every day and have owned since new. 278,000 on it now and it has been the best vehicle I have ever owned.

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.

Ford Super Duty (1999-2016) :: 2001 - Running Rough - Code P0174?

2001 V10- F250.. Runs rough- had the computer put on it and was coming up with P0174 codes (I think that is right)- In any case I replaced the Mass air flow sensor- checked for any vacuum leaks visually- I did not see anything obvious.... still runs like crap.... smells like gas when idling.... anything else I can check??? The check engine light went off finally (probably due to the MAF)- but it's driving me nuts- Any hoses I have not located I need to check?

Ford Super Duty (1999-2016) :: F350 Running Rough When Locked In First Gear

My brother is having a issue with his 99 F350 diesel 7.3 automatic tranny pu. When in manual 1rst gear the engine stumbles and runs like crap. In drive or 2nd gear it runs fine. He's getting a code for a bad cam sensor. A new OEM and aftermarket sensor has been tried with no solution to the engine problem. What might be going on? Maybe a bad ECM.

Ford Super Duty (1999-2016) :: 2008 F250 Running Rough In Low Gears - CEL Came On

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?
