I have a 2001 F250 V10. It idles around 1k and when stopped at stop lights or when put in reverse it stalls. I have replaced IAC, fuel filter, tranny filter, oil filter, plugs, coil boots, tranny fluid, oil, air filter, and PVC along with the PVC hose. I'm totally stumped. It doesn't stall if I do a rolling stop.
View 14 RepliesI 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?
2001 F250 5.4 111,000 miles super duty.
I have a 2000 f250 superduty gas v10 6.8L . I bought this truck about 4 months ago. Now when I take off from a complete stop the truck shakes up until second gear, shifts fine all the way up until the last gear it looses power "loosing power" i mean i can put my foot into the pedal and it takes forever to climb speed meanwhile the RPM'S never skyrocket like it the transmission was slipping if anything a couple times the RPM's dropped are stayed the same then as i take my foot off of the pedal once i have my desired speed sometimes not always the truck will give me a little jerk Also Just the other day I was driving on the highway and decide to put her on cruise control at about 70mph, I set the cruise control and the RPM gauge was just over 2,000 and the tach was fluctuating up and down about 1/16 of an inch. I been reading alot of forums and what I got out of them is it maybe pointing me to a misfire maybe the coil packs? Plugs?It's not something major like a transmission rebuilt.
View 6 RepliesHaving trouble with the truck going into gear. It started by having to put the truck in first and manually shift until in drive, once it finally engaged and would drive normal. But now im having trouble with going into gear at all. What could be the issue????
View 8 RepliesI may be going to look at a 2001 F250, 4x4 with a V10 engine tomorrow. I think it is a shop truck for a business. The owner said that the mechanics told him that the trans won't shift out of low gear. It is an automatic. Maybe something as simple as a modulator valve (do they still use them)?
View 4 RepliesI am experiencing what feels like a "bump in the rear" when initially starting from a dead stop. It feels like a car behind me tapped the bumper or that the truck "hunkers down" first, then moves. Tranny seems fine also. Once moving, there is no problem whatsoever. There atre no noises, leaks, or other symptoms. Also, when coming to a stop, it feels the same way just before the truck completely stops. If I drift forward a little, then apply the accelerator, it does not "slip" or hunker down.
Took it to the dealer and they claim that they can't find anything wrong and may just be the suspension releasing? The truck does this whether loaded or not?
2001 F250 CC Lariat SB 7.3
I bought my son a 07 F250. 5.4L and he tells me it is dying on him, it started out with it trying to die when going into reverse, now he can't keep it running much at all. He took it to the Firestone shop and they are telling him one of the camshafts is probably bad... I highly doubt it. And a new 3k motor is what he needs...
The truck has 145k on it and has been well maintained and just had the oil and fluids changed. Air filter is good, battery is new as well. Only thing I can think of is to clean the throttle body and air meter, he lives 200 miles away so it is hard to troubleshoot over the phone. Any pointers to look at? possible vacuum leak somewhere?
I just purchased a 2012 F250 XLT with the 6.2. It has 38,000 miles on it. Yesterday I noticed, when coming to a stop, the idle will sometimes drop below 500. The engine will stumble a little, then the RPM will jump up to 1,000. Twice it has stalled on me. When it stalls, the engine will restart just fine. No codes in the computer or warning lights on the dash.
I will be bringing it back to carmax, as it is under their 30 day warranty still. Hopefully they will be able to figure out something. I am thinking either the TB needs to be cleaned, or there is an issue with the canister purge valve. I saw the TSB for the CPV but it doesn't cover my truck.
I have an 04 F250 4x4 king ranch with a 6.8 V10.
When I first bought this truck it had a problem of stalling out at stops. You could sometimes hold the brake and gas and push your way through it but it would sputter for a second and try to die and then it was fine once you got going. The OD light would flash, check engine light would come on and it would throw a P0720 code for the OSS. I did some researching and I pulled the sensor in the pumpkin before that because I read that could cause the same problem, so I cleaned it and put it back but it didn't solve the issue. Then found that an K&N air filter can often times clog the MAF and cause the issue so I pulled my air filter and sure enough it was a K&N, I swapped it with a normal filter and sprayed some MAF cleaner and its been running like a top for months... until now.
It started again, gradually at first. It would die when I started to back the truck at a very low speed to load my 4 wheeler. I fired it up and it was good again for a couple more weeks, then I went to hook to a horse trailer and I was having to back up a hill to get to it, and it just kept dying, OD light would flash, check engine light came on. I was in a bind so I just tried wiping off the MAF with a rag, that didn't work, my girlfriend was using the truck and said it kept dying whenever she stopped. I got it home and cleaned the MAF with cleaner really well but the problem persisted. I went ahead and changed my oil, spark plugs(gaped at .052-.054), replaced the IAC(which looked like it had been installed once before so I am guessing someone tried it and when it didn't fix the problem they returned it) and changed the fuel filter. I drove it around and it ran fine, drove it to work and it ran fine, my girlfriend took it for about 15 minutes to run an errand for me and it was fine until she got back in the parking lot and liked to never got it parked again it stalled so much.
So I went back to the drawing board and read that it is rarely the OSS that is the problem but that often times the issue is a bad coil pack. I don't have a scanner nor do I know how the heck to use one. I plan on going out of town at the end of the week and the truck has 194k miles on it so rather then take it to a shop and try to find out which COP was bad I just decided to replace all of them(I know, I know, you should never just start replacing parts). I only had time to replace 5 of them, I took the truck out and again it dove fine for an hour, went through traffic OK. It sat for an hour and when I left it started to die again, I could drop it in neutral and it would fire back up and as long as I gave it just a hair of throttle it stayed running fine, take my foot off the fuel and in a minute it would die again. After I drove for a bit it was fine again. Now I know the problem may yet be in the remaining 5 COP that I must change tonight but in case it is not I wanted to get input on this.
I've read the problem can come from a bad ground, so I took every ground point that I could find under the hood and I cleaned the connectors and took the paint off at the connection site just for good measure. The problem persists. I've read that sometimes a diode can go out on the alternator and cause this problem, I did use my amp meter and I'm checking out at 13 volts while running. I'm not the best with meters so I'm not sure how else to check the diode?
I've also read that taking it to a dealership is hit or miss for them diagnosing the problem, sometimes they find the issue, sometimes they just change the OSS. The only mechanic I trust closed his shop and is now service manager of the Dodge dealership. I'm thinking since this seems to be a common problem that maybe ford might have more knowledge of it then dodge but I trust the dodge dealership more because of who is over it. Either way I know it will sit in a dealership for awhile before it ever gets looked at and if they have to chase any electrical problems then that starts racking up $$ fast.
So what am I missing? I've thought about replacing the MAF since cleaning it the first time solved the problem. When it did this the first time I still had my 01 F250(it never gave me problems like this) and so I took the MAF off of it and swapped them and sure enough it fixed my problem so I switched them back after I cleaned the MAF and like I said it's been running fine until recently. I'd rather not throw money at this by replacing parts and hoping for the best. I've also read about tracing the harness that runs from the sensor on the pumpkin to the OSS and on. That harness runs through all kinds of stuff so I'm dreading that but it will also be a next step. I haven't pulled the OSS because its in a very awkward position on my truck.
My '05 (134k, rwd, V10) has had an occasional issue with stalling when going into neutral. The normal idle speed in park or neutral is 700. In drive or reverse it dips down to 350 or so and then evens out at 500. The stalling is not all the time, perhaps 2 out of 10 shifts. It is slightly worse with the A/C running. Every time it stalls, it records a P0506 error which I then clear out with my ScanGauge II.
I have done some research and have replaced the air filter (super dirty), fuel filter (not sure on how old) and cleaned the MAF tonight. For the MAF, I pulled it from the air tube and gave it a bunch of squirts of MAF cleaner. I did this 3 times letting it dry in between cleanings. I have run a bottle of SeaFoam through it, as well. The idle seems to be very smooth and it pulls my 7k travel trailer without issue. That did get a little better with the new air filter and fuel filter.
I went for a ride tonight and the problem persists. I'm taking it in to have the A/C recharged next week and will have the shop diagnose it. I came across this post which details my issue exactly. The steps are to reprogram the PCM and TCM, and possibly replace the throttle body. Is the reprogram something an independent shop can/should do?
P0506 idle lower than expected on 05 ford f350 v10
Bought this truck a few months back. Nothing but problems. I always thought it has felt a little underpowered and hesitant. I chalked it up to being a 5.4l in a f250. Well now im thinking it has been a symptom all along.
Lately, the truck has been stalling at stops. Randomly, but not often. The truck idles at 750rpm when I start it, but after driving and then coming to a stop while in overdrive it idles at 400rpm. This seems too low to me.
It hesitates occasionally when giving it throttle. Just today it got really bad and was almost unresponsive. I would hit the throttle and it would just idle while randomly kind of shooting up in RPS and shuddering. It finally produced some error codes, it looks like, but I am afraid to drive it all the way to the autozone.
I am thinking TPS. Is the TPS attached to the pedal or is the TPS attached to throttle body under the hood? I've read some conflicting stuff about this. The good news is that if it is the TPS then it should act like a whole new truck after I replace it.
The 2003 F250 5.4 Superduty has no power and keeps stalling. If I floor the gas it just stalls. I've replaced the pcv valve and line, the fuel pump relay, the fuel pump, and cleaned the tank, changed out the gas, added Lucas, and it just won't run right. Desperate, and no codes are coming up...
View 5 RepliesFriend's truck started shifting wierd the other day, starts in second gear (maybe higher). The transmission is a fresh rebuild, the shop wouldn't warranty the rebuild and blamed electrical problems outside the tranny. Fuses are all good, engine light is on but the cheapo code reader won't show a code. Did a search and no answers. Had the overdrive light flashing from before, that code was for a wheel speed sensor.
1999 F250 (7 bolt) 5.4L 4x4
i just bought a 99 F250 4WD with the 5.4 in it i put a brand new starter in it. When i turn the key to try to start it, it just cranks the motor once and stops. The starter isn't grinding or clicking, the motor clicks once and move the belt and pulley a little but that's it. What would cause this?
View 13 RepliesI have an issue with a truck I just bought. Sometimes, it doesn't go to Park when I shut it down. In order to start it I have to sometimes put it in neutral. Once in a while it will start when in the Park gear. What I should look into to fix it? It doesn't seem like a big deal.
View 6 RepliesI have a 1999 F-250 V10, I went to get into my truck to go to Lowes and only to learn I forgot my wallet. Here is where my problem lye. I came back home and decided to wait until the next morning to go back to Lowes, so I go to get in my truck cranked it up and went to put in reverse and it didn't move. It is like it is in neutral; so I went and put it in drive and still, it would not move. It is like it is in neutral. I can not figure out what is going on with my truck.
View 12 RepliesKevin here, and I'm a newbie. I recently purchased my first 4x4, a 99 F250 with ESOF. Last night I had put it in 4high for a rough road turn-around and then flipped the switch back to 2H, the 4x4 light didn't go off. Then when I got to the house (about 1/2 mile), it rolled when put in park and now it won't go into any gear.
View 7 RepliesFriend parked his well working truck and when starting it up after sitting a few days it won't shift into any gear. Lever moves as normal but the truck won't move. A soft clicking sound is the only difference to be noticed when shifting the lever. where to start? Temps are below freezing here if that matters.
View 11 RepliesHave an 06 F250. When I slow down to make a turn then accelerate it's like the drive shaft spins half a turn before it catches. Been doing it for awhile now. Now I'm get a clunk when I come to a complete stop. When you stop then truck settles there is a little clunk. Does this sound like the slip yoke problem?
View 1 RepliesI have an 03 f250 5.4l that I've been having some problems with. When the engine is cold it will drive fine and everything. When it warms up, if I go to put it in gear it just dies right away. Why?
View 1 RepliesI have a 2008 f250 with 6.4. Was sitting my truck with key on and motor off listening to radio on lunch and my wipers came on by themselves. Switch was in off position and we're in slow speed. If I turn switch they wouldn't change speed til high position. Turned key off and back on and they came on still. Pulled 30 amp fuse in battery junction box to shut them off.
