So, my truck runs really rough when I am @1500 RPM and lightly feather the gas. I have replaced all coils and plugs. Used dielectric grease. Replaced air filter, replaced ICU, changed transmission fluid. The thing still "shudders" ... 2004 f250 5.4 ....
View 14 Replies2004 F250 V10, runs good until it warms up whether it's hot or cold outside. While on freeway, it really shakes while cruising, but of you get in the gas enough for a kick down, seems to be pretty smooth. I've changed the coils, and 9 plugs (one wouldn't budge, but the others I took out looked fine) to no effect. Where else should I look? Also, no CEL, and no codes, which seems odd as bad as it feels...
View 11 RepliesI 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..
View 5 RepliesI have an 04 6.0 F250. I am having a shaking between 1500 and 2500 RPM around 45 - 55 MPH. I have no guesses what is calling this, but the truck runs fine otherwise.
View 8 RepliesMy truck started running poorly with an intermittent miss about 6000 miles ago. The miss gets more consistent when the tank is below 1/2. Fill it up and the miss goes away. No codes, shop that does a lot of V10 camper work could not figure it out.
My guess is that the fuel pump is going out and it overheats when the tank is low. The problem is getting progressively worse. Now it misses slightly with 3/4 tank and even a full tank sometimes.
Plugs have been changed, fuel filter has been changed, and the shop found 3 COPs that were bad before all this new intermittent miss started. The truck runs ok at wide open throttle.
Am I just nursing a bad fuel pump that will leave me standed soon? Truck has 170,000 mile with original fuel pump.
Have a 2006 F350 5.4l that is mainly used as a plow truck. I drive it at least once a week when not plowing just to make sure it runs ok, etc. Only put on about 2,500 miles per year. Keep it in good repair - not by me, but by the dealer or mechanics.
Problem - last two times I started it, it started ok but runs real rough for about ten seconds. Sounds like the engine is going to die. After about ten seconds, it "catches" and runs normal. Have no problems when driving it. If I restart it, it doesn't do this, so it seems to only happen when the engine is cold.
Battery was brand new back in Sept. All plugs were replaced maybe 3 years ago, as was the cat converter and muffler. Run non-ethanol fuel. What might be causing it before I bring it in.
Getting these lean codes P1131, P1151, P0171, P0174. I was getting a knock sensor code before but not now. It will not idle it just dies and runs rough till I get at higher rpms gotta feather the brake and gas to go anywhere.
View 5 Replies2002 f-350 diesel 4x4 7.3l. It stalls out a few times lately( and starts right back up) and it runs rough like there is an air bubble then smooths out. Changed 1 fuel filter and the pcv valve. 96,000 miles.
View 6 RepliesI have a 2000 F-250 Diesel that has started acting strangely. It starts and runs well, but every once in a while the peddle just stops working. Might be a second or so and then the RPM will go up. Or you may be running down the road and all of the sudden it just stops acting like it is getting enough fuel. Same thing it might last a second or so. Sometimes it might happen 4-5 times in a row over a few minutes and might not happen again for a day. Truck does not stall when this happens. It just does not go like it should.
View 1 RepliesI have a 03 250 5.4 with 160k. I just recently replaced #4&3 coil packs. Truck was running great again. Then a few days later the truck was running extremely rough and white smoke from the exhaust. I noticed the pcv valve was not all the way in(pretty much out) put it back in and ran fine for two days now running rough every now and then and the pcv valve is making a vibrating noise but stops if I pinch it slightly. I did replace the plugs a year ago.
View 14 RepliesLet me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.
View 4 RepliesI just brought home an 04 F350. It is a V10, 6 speed, with 30,600 verified miles on it. It runs and drives fantastic, and that V10 is impressive! I am very impressed. I have noticed that the compressor cycles, even with the dial in the off position. Is this normal for the super duty, or is something amiss? If something is wrong, what direction do I look in?
View 13 RepliesI 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.
My 2008 F250 Super Duty is riding very, very rough. I put in new heavy duty Bilstien shocks 2 or 3 years ago, and I would think they would last longer than this.
Are they any other causes I can look at to see what is causing this truck to ride rough?
I recently purchased a 1999 6.8L. Runs great when cold but after warming up the idle gets rough. Truck has new plugs and coil packs and fuel filter. Checked the fuel pressure and the idle is right at 30 psi. I read that the good pressure range is 30 to 45 psi. Is 30 psi acceptable or should I replace fuel pump or regulator? Any next step to solving my idle woes.
View 3 RepliesI am new to the v10 I only ever owned 7.3 this is my father truck it's a 99 with 200k on it. The problem is it will idle fine when cold but when it is warned up very ruff idle no codes and when I go back at the end of this week I will check the O2 sensor with AE but I really don't know much about it.
View 2 RepliesI 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.
View 2 RepliesI have a 99 f250 5.4l 2v with 165000. just two weeks ago i went to start up the truck on a job site to take lunch and it was running really rough. I talked with a mechanic at my shop and he said that it sounded like the aic or that i needed plugs. I went and bought aic and plugs and installed them all in one day. I unhooked the battery before i did any work and have changed the coil packs about 3-4 months ago when it was jerking at highway speeds. I am at a loss.
Read so much on the site about could be this or that and cant afford to through money at it like the govt does. I replaced the ait(air intake temp sensor) and the ect(engine coolant sensor) after i got a code from oreillys that said p0113 which is high input on it. I have read it can be so many things and it seems to be running rich because i am getting about half of mileage i was getting before problem started. i need a fix soon as i must drive the truck to work everyday which is a 52 mile trip total.
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 RepliesThis 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.
View 14 RepliesOn a 2003 5.4 f-250 XLT 4 door, long bed
Running 285 tires, none lifted, factory lifted for snow plowing? Did have a plow mount when purchased used.
Had the truck over a year now & love it. My only real dislike is the stiff/ rough ride when empty, which is 80-90% of the time for me.
I know my truck & year have leaf springs with shock dampeners on the front, vs the coil spring and shock dampeners that came in the later years for a much improved ride. Also my struts are "Rough Country" which from what I understand are cheaper shocks. Had a 04 Tacoma I replaced with Bilstein 5100 shocks after leveling it & it was an amazing difference. So that's my only real comparison in shocks. I've read of guys replacing their entire front end for the coils & springs. Not interested in going that deep into it for a better ride. If that's my only option, all be happy with the ride as is.
What are my options if any? Better shocks/struts? Other than my rough country that are on the truck? Purchased used a year back & never felt the "stock struts".
I did find Bilstein 5160' s for my model truck. Link : [URL] .....
