Ford F-150 (2004-2008) :: 2007 - Hard Vibration At Idle
I bought the truck last November with a bunch of issues. My most recent problem is a hard vibration at idle. No it is not the infamous misfire and stall. All timing components (chains, tensioners, guides and vct solenoids) have been replaced.
I've replaced the ignition coils, spark plugs, air filter, and fuel filter. When I'm at a stop light or just idling in the driveway I can feel the vibration in the cab through the seats and the steering wheel. I can see the drivers side mirror vibrate but not the passenger side.
I've seen posts that are saying that this vibration is normal, but it seems a but harder of a shake than normal. Would there be anything that would only affect the driver side bank and not the passenger side?
Ford F-150 (2004-2008) :: Idle Vibration / Hum Coming From The Engine
When the truck is idling it has a weird vibration and their is a hum that comes from the engine. It then clicks like my clutch fan disengages or engages and both go away. I have only noticed at stop signs and sitting in a parking lot. 2004 5.4L....

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) :: Rough Only At Idle Constantly
Is it possible to have an intermittent injector problem I am having the same problem with my 2004. Its not all the time its rough only at idle constantly. If I keep the rpms up it doesn't do too bad...
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?

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) :: 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)...

2005 f-150 4.6l v8 rough idle only when truck is to normal operating temp. I have run several gas system cleaners through the truck. I replaced the air filter, the fuel filter and the spark plugs. I am only getting 14to 15 mpg mostly highway. No DTC's are showing up. The truck only has 50,000 miles.

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.
Ford F-150 (2004-2008) :: Rough Idle / Truck Wants To Stall
Let me describe this perplexing issue. I have a speratic rough idle problem. When it happens it's almost like the truck wants to stall. Once going the truck is fine. There has never been any acceleration issues, but for a short time the truck would kind of lunge off idle. It hasn't done that for quite some time. I've replaced the fuel filter. There are no vacuum leaks that I know of. I've tried higher octane fuel. I've tried injector cleaner for a month. What should the fuel pressure be and what is the test port located? Is the fuel pump in the tank? If so, whats that big log looking thing behind the gas tank that the fuel lines run to? Also, there are no MIL codes...

I recently bought a 05 f150 with 5.4 3v and 195k miles needing some work. Ran great, just had a code for timing over retarded. Originally it had a cracked timing cover, so i took it off to replace and found broken guides and bad tensioners on timing. I installed new guides, chains, and tensioners, and cleaned phasers, and put back together only to find it ran terrible and had a phaser rattle. I then went in and installed phaser locks, which took care rattle but not the running issues. I can not figure it out.
ISSUES: My issues almost mirror what is said in this thread here, but this issue was never solved. [URL] ....
My issue is when started cold it starts right up, idles ok, runs ok, although a bit sluggish. Once its warm it stalls at idle, shudders when giving throttle in overdrive, and if you kick it down it will continually backfire, and slowly accelerate... it kicks down but acts like its only getting 1/8 throttle, just kind of hangs at the same rpm and slowly climbs in rpm. Sometimes it wont backfire as much, and sometimes the check engine light flashes. After it stalls at idle and you start it back up it sounds like it shudders/backfires for a split second then starts.
It is throwing many engine codes, but most are from the phaser locks. Throws code for timing over advanced on each bank (phaser locks lock them fully advanced), cam timing codes for each bank, and then a code that doesn't have to do with the timing, P2106. I am going to run some live diagnostics on it today and report back but I am fully at a loss.
Ford F-150 (2004-2008) :: Rough Idle When Come To A Stop And Even Stalls Sometimes
I have a 2004 FX4 5.4 with about 113,000 miles on it. Lately, when towing the camper (around 7000 lbs), truck runs great. However, when I come to a stop, it idles horribly and even stalls sometimes. When I rev it up, runs fine again. It only does this after towing when engine is under load for extended periods of time.
The only code it has ever thrown was for bank 2 camshaft over retarded. My thought was that it could be VCT solenoid for bank 2...
Ford F-150 (2004-2008) :: 4.6L Engine Hesitation And Rough Idle
I have a 2008 Ford F150 4.6L and its been broken down in our shop for quite some time now. It started acting funny when I could not get the truck to do over 80kmh. Slow acceleration, and a horrible shaking when it idled. Eventually it was undriveable since I could go above 50kmh anymore. From looking online we replaced the plugs and coils. We removed the intake to find the gaskets were shot so coolant was leaking into the spark plug tubes which could've been the cause of a misfire. Fixed that. Still the same. We replaced the egr valve and dpfe sensor because we keep getting the P0402 excessive egr flow code. Still no luck. My dad is a journeyman hes just not too familiar with newer trucks.

2004 Ford F150 5.4 Triton 3V Vin5.....
How this started, Drove through a lot of water as our City was in a flood on my way home and and the truck started running rough and got worse over time, I can now barely get to 40 mph as it starts to ping and sputter with no power.. the truck has been parked and not driven while in the shape it's in.
The truck keeps giving me error code P0303 Cylinder 3 misfire detected, P0174 System too lean (Bank 2) and at times another error P0300 saying multiple cylinder misfires detected.
After clearing the codes, I got new codes stating Misfire on Cylinder 2, 3, 4, 6. System too rich (Bank 1) System too lean (Bank 2)
Cleared the codes again and I'm back to Cylinder 3 misfire and System too lean (Bank 2)
What I have done so far... All repairs with in a few days...
1. Changed all spark plugs.
2. Changed all Coil Packs.
3. Changed number 3 fuel Injector.
4. Changed the Oil and Filter. (no water in the oil)
5. Changed the MAP Sensor.
6. Changed Bank 2 O2 Sensor 1 and 2.
7. Loosen the Catalytic Converter on the drivers side to re-leave back pressure thinking the Cat was plugged, still loss of power. I also drilled a small hole in the exhaust at my lowest point to see if it had water in it and it does not.
Checked for vacuum leaks using starting fluid around the intake manifold, no change in idle.. I also checked to make sure the vacuum line was still connected on the back of the intake manifold, I have found nothing leaking.
I also had cleaned the throttle body and changed the throttle position sensor.
Repairs within the last 6 months or less...
8. Replace passenger side cat.
9. Replaced both Bank 1 OS Sensors
9. Replaced Timing chains, Gears, Guides, Guide Tensioners, Oil Pump and pickup tube, Water Pump.
Cam Phasers are fine.
And number 3 coil is getting spark I changed the Ignition Coil again thinking maybe another bad pack.
Still #3 misfire and System too lean (Bank 2).
I am at a loss and not sure what to try, except for a compression test on cylinder 3 but I honestly don't think it's compression or a burnt valve.
Ford F-150 (2004-2008) :: 2006 XLT Started Running Rough Out Of Nowhere Near Idle
I have a Ford F150 XLT. I have 67000 miles on it and the other night it just started running rough out of no where near idle. Once you got over 20mph the rough running would go away. I took it to get an engine change and engine flushed but it came back. It doesnt always run rough near idle or below 20mph. The Ford dealer says my engine has only 22 psi oil pressure near hot idle and cant engage the VCT phazers and they want to replace the whole engine.
