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.
Ford Super Duty (1999-2016) :: 2001 - Running Really Rough?
My wife was using my truck and she felt it lost power and ran rough, so she pulled over can contacted me. We both are deaf, but I can hear some and it sounds really bad. So, I had it towed home and I recorded it.

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)
Ford Super Duty (1999-2016) :: 2001 - Engine Running Rough While Accelerating?
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.

Here is my situation : I have a F150 1999 4x4 ext cab with 326 000 km. A little while ago I got a P0401 code so I decide to clean the TB first and at the same time change plugs and wires since they were overdue. The same code came back and a misfire. Ordered EGR valve, DPFE sensor and selenoid. Realize that I had ordered crappy plugs by mistake. I change all plugs. Had to wait for the EGR valve and others to arrive. I drove the truck for a while since I did not have the time to change the valve and others, during that time the misfire did not come back. Yesterday I change the EGR and others. Today I get a truck that runs really rough and got new codes , P0305 and P0174. I'm really confused now on what should be my next step, should I change the coils, can a P0305 cause a P0174. Should I change vacuum hose going to the EGR , selenoid and DPFE.

Wife took truck out and turned around after going less then a mile, saying it was running very bad. We got this truck about two months ago at a state vehicle auction. It was a state used truck, 145,000 miles, 05 Ford F350, ext cab and 8' bed. Anyway at first I thought it was valve tap until research said an exhaust manifold. With a fog machine in rear exhaust pipe we confirmed it was leaking and replaced the exhaust manifold. Figured it was probably a good time to replace spark plugs too. Took truck for a ride and she still buck and farted.
Got a code machine and got P0171 and P0174. Couldn't find a vacuum leak, but your could hear the air being sucked in. went to local parts store, guys couldn't find leak, but they said truck sounded like a steam machine. today I made a homemade smoke machine and smoke came from air intake, figured the gaskets were bad. The pictures show what I saw when I took the gaskets off. The port that has melted is the same port were the exhaust manifold was leaking from. Am in deep "doo-doo". What caused this?
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.

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.

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?
View 1 RepliesFord Super Duty (1999-2016) :: 2002 7.3L Running Rough On Cold Start Ups
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.
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) :: Engine Is Running Rough (jerky On Acceleration) Especially When Driving
I have a 1999 F250 SD V10 4x4. I recently had a transmission installed and the truck is running erratic. I have an engine miss (sometimes when idling, more so when in drive and foot on the brake). I say sometimes because there are times it will not miss and the engine runs smooth. The transmission shifts a little strange and sometimes hard.
I am getting a code reading that says my TPS is faulty, but I installed a new one a few months back.
The engine is running rough (jerky on acceleration) especially when driving. I was wondering if I should take it to a shop and have them flash the computer to reset it?
I also remove the AC compressor a while back (bad clutch). I installed an aftermarket pulley.
Ford Super Duty (1999-2016) :: 2002 F250 V10 Rough Idle / Not Running Perfect
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.
