Ford F-150 (2004-2008) :: 2005 - Rough Idle And Stalling
I have a 2005 5.4l f150. 105,000 miles. Recently While on a trip I experienced rough idle and stalling at idle. I drove it home 2hrs. The ride home was challenging. Poor acceleration, rough idle. Took it to the dealer and was told I needed plugs and I was 5qts low on oil! Not sure where the oil went. It hasn't been leaking and never seemed to burn oil in the past. They did the tune up. Picked up the truck. It ran fine while cold. Upon warming up it ran rough at idle and stalled just like it did before. Took it back, they said "you need a new engine. Upon warming the oil pressure drops indicating internal engine damage". I took it to a local guy he says replacing the cam phasers might fix it. What's the consensus, should I try the cam phasers? Look for some other potential problem or trust the dealer? (They did refund me for the tune up)...

I just purchased my first F150, 4.6L V8, 55,600 Miles. It intermittently has a rough idle and only seems to be when the engine is hot. I've had engine and tranny mechanics look it. The spark plugs have been inspected and are within an acceptable range. The throttle body has been cleaned. There are no trouble codes of any kind. What I can check next?

A week and a half ago I went out to my truck to go somewhere and I got about 2 blocks away and the truck started running really rough and had a big lack of power, so I turned around and scanned it with my code reader and the codes I got were p2271, p2196, p0303, p0012, p2197, and p2272. since then I've changed all the spark plugs, boots, swapped all the coils and injectors from a great running truck, fuel filter, and the bank 1 upstream O2 sensor.
the other thing that came to mind that could of caused the problem is that a few days before the problem started. I jump started a co-workers car and he hooked the cables up backwards on his car. Could this be the cause of the problems I'm having.
The truck is an 05 F150 FX4 5.4 with 180,000 miles on it.
Ford F-150 (2004-2008) :: 2005 5.4L Intermittent Rough Idle When Warm
I have a 05 fx4 5.4L with 85k on it. It has started idling rough when i come to a stop light or slow down to 10 mph or less. It only does it once in a while. There doesn't seem to be any real pattern. The motor shakes until you rev it up and then it goes away.
I have cleaned the maf, put in new air filter and fuel filter. And put in a new battery. Would a coil act like that? Maybe plugs? Or a vacuum leak?
Ford F-150 (2004-2008) :: 2005 - Rough Idle - Power Loss?
my f150 running right so i can enjoy it like everyone else does. I have a 2005 Ford f150 with a 5.4 auto.
It has a rough idle(shakes the truck), very little power, and poor gas mileage. Randomly It will throw a code for misfire on 1 and/or 3 on start up only. It does seem to perform better within the first few of starting but dies right off after that. In fact i got stuck in the snow the other day and it could barely break the tires loose to try and get it out (almost put in 4low cause i didn't want to hurt the trans). I have replaced:
Cats
Fuel pump
Plugs (motorcraft)
Random Coils
Did the timing chains and phasers
MAF
All new injectors
Intake gasket
Was at my mechanics and had a scanner on it and at idle the 1-4 cylinders are all show a negative cylinder contribution. But when you rev it up they all go to 0 across the board. Was kind of thinking about the Variable Timing solenoid.

I have a 2005 F-150XLT with the Triton 5.4L. The other day while driving on side roads (Paved, not back roads) I noticed my CEL on and it was blinking. There was a very rough idle as well as a big loss of power. When I pressed the gas pedal it was sluggish to say the least. I have yet to get a computer on it, since I had to order one. There is also a light gas smell, only smells near the rear of the truck. From what I am guessing, I think it is either a spark plur or a coil over pack, Truck has about 56K on it.

View 7 RepliesFord F-150 (2004-2008) :: 2005 - Rough Idle At Low Speeds Primarily In Reverse / Code P0022
2005 f150 Lariat 4x4 5.4
Had phasers, tensioners, chains, guides, and sensors replaced. After driving the truck, it started to get a rough idle at low speeds, primarily in reverse. Changed both vct solenoids with no results. Started to get p0022 code. Changed the oil with motorcraft filter and 5w-20 twice after the work had been done, thinking it might need it. Vct's were a little varnished, but not too bad.
After a couple days of light driving, got a misfire on #3. Replaced the coil and it hasn't been back since. I am stumped at this point.
The computer show the timing to be at +13 when sitting stopped and in drive. It fluctuates a little, but not much. When the truck goes into a rough idle. The rpm's fluctuate wildly. It seems to be happening more frequently, the more I drive it.
Ford F-150 (2004-2008) :: 2005 - Idle Really Rough / Revs Will Rise And Then Drop Again If Blip The Throttle
I just locked out the cam phasers on a 2005 f150 with a 5.4. It now idles pretty rough. If I blip the throttle the revs will rise and then drop again, and it barely catches in time to prevent a stall. If I continue to tease it this way I can usually get it to stall. I'm getting no CELs or anything, but I intermittently will get a P035x code (it seemed to rove. I've gotten cylinder 1, 4, 6, but not consistently.). I have chased those around by swapping coils, checking/cleaning the connectors, etc.
I am kind of thinking that these codes are a symptom of my idle issues, and not the actual problem. What could I have done wrong? Could it be a vac issue? I had basically the entire ECU harness and all the vac lines disconnected to do the job, but as far as I can tell everything has been reconnected to the correct locations. I did have an SCT tune done to remove the phasers in the ECU. I installed it and still have the issue, so for now I am on the stock tune just to eliminate any variables.
Could my tune be the issue? Is this how you would expect the engine to behave with locked out phasers and no corresponding ECU tune?
Touareg :: 2004 V6 138K Miles - Rough Idle In Neutral And In Drive When Stopped
Recently noticed the idle seems rough in Neutral and in Drive when stopped. When the roughness is subtle, that RPM gauge doesn't move and at other times with more pronounced surges the RPM gauge bounces around. Not sure if it is related but we just got back from a couples days in Tahoe. Tried reconnecting the gas cap with no change.

I have a 2006 f150 I just bought after my F250 was stolen. It has about 70k miles. It has been running pretty rough ever since I got it. It finally threw codes so I tried to address all the issues. Changed out a couple coils and all the plugs (motorcraft platinum). The camshaft sensor was also bad. Truck runs much better but still has an idle issue I cant seem to nail down.
I assume its something to do with air intake. It doesnt happen all the time. It runs rough and knocks and sometimes dies. If I give it gas it stops. I read it could be the idle air intake valve, but then I read that this model doesnt have one. I also read that air intake issues dont normally throw codes. Are there any common problems I could look for? Would cleaning the throttle body do any good?
I know the basics, but this kind of thing is tough for me to troubleshoot. You may have already seen me post this problem, but I didnt get much response so I thought I'd try one last time.
Ford F-150 (2004-2008) :: Rough Idle Intermittently?
Ok, so I just replaced the entire timing set (phasers, chains, sprocket, tensioners ect) on my 2004 f150 5.4l about a month ago. I also extracted ALL 8 spark plugs and replaced those with the Champion 1 piece plugs. In addition, I replaced the intake manifold because I did this job when it was 20 degrees outside and I found a crack. Soooo, all that being said I put the whole truck back together and it runs like New. Until about a month later. When the engine gets hot, maybe after about a 30 minute drive or so, it has a really really rough idle until I give it a little bit of gas. Then it clears up. It has only done it 3 times since I put the engine back together. It might go 2 weeks and not do it. No codes. What I could be? EGR? MAS air? Only other thing I can think to say is if you get on it out on the highway, after about 3k rpms it seems like the power drops off quite a bit. Like the engine isn't getting enough fuel. I guess it could be just me, but it just doesnt seem right.. I guess I could try to unplug the MAS air flow sensor...

I hopped in my truck this morning, fired it up, and it idled nicely. I drove around the corner, and noticed that the truck was barely responding to the throttle. Then things got shaky. It was a very rough idle, almost like a misfire. But I managed to get the gas to respond and got the revs up to about 3K and it seemed to run smooth.
No CEL either. Currently, I have no place to really look at my truck as I don't have a garage, or driveway for that matter. I don't have a scanner that can read live data either. I'm limited in my tools currently as well.
Ford F-150 (2004-2008) :: Bad Vibration Or Rough Idle With AC On
I have 2008 f150 with 5.4 and 54000 miles. It has a bad vibration or rough idle only when AC is on. When AC is off it runs very smooth. Runs great while driving with AC on. Tensioner pulley was moving a lot more than normal when engine started vibrating so i replaced it and the belt but it didn't work. I also checked the other pulleys and they are good.

View 1 RepliesFord F-150 (2004-2008) :: Rough Idle When Put It In Park
An injector stuck open on my 05 5.4 and bent a rod. I had a new rod put in and all new revised Motorccraft injectors. This was about a month ago. Truck has ran great for the past 3 weeks until today I put it in park and it idles real rough, put it in gear and it smooth as butter again? (Once in a rare while it will continue to idle rough in gear for a few seconds but then clears up.) New motorcraft plugs were put in right before it bent the rod. The truck runs real strong other wise. I am about done with ford this pickup has been the biggest pile I've ever owned one thing after another and just when I think its fixed its some other stupid problem. I'll start by cleaning the maf and throttle body. Could it be a bad coil?
View 3 RepliesFord F-150 (2004-2008) :: Rough Idle When Engine Is Warm
I purchased an '08 F150 about 6 months ago, and have a problem that two mechanics haven't been able to solve. The truck has a 5.4L engine. Unfortunately, I bought from an auction and the 30 day warranty expired before I realized the problem.
After a longer drive (30 minutes to work) the engine is warm, and I always back into my parking spot or driveway. In low gear, it begins to idle very rough and the engine shakes. If I leave it long enough, it will stall. Usually I pop it into neutral, give it some gas, and its fine. I just bought a camper trailer, so I'll need to use the lower gear when backing up.
So far, the engine has been flushed twice, the solenoid replaced and phaser replaced. The second mechanic has recommended I contact a dealer, but haven't had luck with them with my previous Explorer. What it could be? I will be getting the diagnostic paperwork this week.
Ford F-150 (2004-2008) :: Idle Really Rough When Put In Reverse After Oil Change
Okay I have a 2006 F-150 5.4 60,000 miles , Never once had any problems. I have always done the oil changes myself using 5w-20 mobile super and an S2 STP oil filter. Today, I did a normal oil change and once i filled it up I checked the oil it one last time and I topped it off just right according to the dipstick. And I also checked it after letting engine idle for 5 minutes. I changed the fuel filter also ( first time doing) but no leaks. I drove about two miles down the road, turned around and when I put it into reverse it idled really rough. It almost sounded like a thrown rod.
The rpm's dropped to about 500. I put it into drive and gave it a little gas and then all was fine. Engine ran perfect. I reversed it at least 5 more times and it did it every time but always recovering when given a little gas. I also noticed that there is some oil splashed on the undercarriage like it was leaking going down the road. I checked the filter gasket and it was fine and intact. It idles great in park, drives great. Just reverse it dives down and vibrates like crazy.? After getting home I noticed that the oil level on the dipstick is a little less than a 1/4 inch over the correct level.
