Ford F-150 (2004-2008) :: 2007 Won't Run / Engine Would Shake At Idle When Hot
Feb 26, 2015
I have a 2007 F150 with the 5.4 FFV. Early last summer my truck started acting like the harmonic balancer was going bad, when it was hot out my engine would shake at an idle. Then in October it threw a check engine light, wouldn't get over 20 mph and was shaking the entire truck. The codes said my timing was out so I replaced the timing chains, guides and tensioners, which were bad on the passenger side. When I started it back up it ran rough, and the check engine light came back on with a "bank A over-retarded" code.
So I went back in thinking I had put the chain on one tooth off. Got it back together and it ran the same way. After doing some soul searching on this website I determined the VCT Solenoid for the driver's side may be bad, and I went back in a third time and replaced the solenoid. Now it runs worse than it did the first time, it won't even idle and it is nearly impossible to start in the first place... This truck only has 103,000 miles and was running great before this...

Im trying to chase down an engine miss fire on a 2007 with the 5.4L. It only seems to miss under no-load conditions, such as at idle and on a downgrade while driving. Acceleration and under a load it runs fine. New Champion plugs were installed at 135,000 miles. The truck now has 150,000 miles and has only been miss firing for the last 1,000 miles or so. I pulled the connector off of the coils one at a time to try and figure out which cylinder/s were missing. I thought I found the problem ones and replaced two of the coils, but it ended up not fixing the issue. Ive tried spraying carb cleaner at and around the intake to check for leaks, but found none. I have a scanner, but the check engine light is not on, so its not much luck.

Still showing the same codes (per repairman) and still having the intermittent rough idle at low speeds when the engine is warm. It has been so intermittent that I could almost live with it.
So repair guys first replaces the VCT's and runs fine until warmed up and the problem reoccurs with the same codes. He replaces both cam phasers and tensioners today and still same problem and same codes which point to the VCT and cam phasers.
Truck has 80k, city driven, oil changed every 3k or so. Burns ethanol and still runs great at speeds over 10 mph even when this problem appears.

Here's another idle problem. I have a 1992 aerostar, 3.0 2wd with 245,000 kms.
I have been working on this van for weeks now getting it ready for summer. I have done a complete tune up consisting of wires, plugs, rotor, cap, pcv and all filters including gas, air and oil. I have checked the vacuum hoses as best as I could and all seem fine.
Here.s the problem. I start the van and it idles great. The engine doesn't move. After a few minutes it slows down a bit and starts to shake. Once it is completely warm and has been driven for an hour, it shakes noticeably. It has lots of power and gets good mileage. It never has a starting problem and never seems to be close to stalling. I am suspecting it is one of the various pollution control items such as the MAF, IAC or 02 sensor. Is there a way to check them at home?
While under the van, I noticed a cable that goes from the transmission into the firewall. A bracket holding it in place broke and the cable was rubbing against the exhaust pipe and burned through. Could this be related? I taped up the cable and tied it up and away from the pipe.

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?

I just got done with 2007 5.4 Triton with cam phaser noise. I replaced phaser, timing chains ,tensioner, oil pump, and it still made noise at idle when it was hot so a change the oil to 0w40 and my noise went away. 5w20 starts to brake down at temp of 180 but 0w40 works up to 212 ford will tell you all you need is 25psi of oil pressure what I have seen is you need at least 40psi of oil pressure so if you have noise try 0w40 mobil1....

When my Camry is in DRIVE and sitting at a red light for example, my car will shake. It feels like it idles rough. If I put it in neutral the shaking goes away... only when in drive.
I took it to Firestone who mentioned I had a dirty throttle body. So I get this cleaned and the shaking has significantly reduced. However after a few months I'm back at square one. Dirty throttle body and care is shaking again. (Yes air filter is clean)
I noticed two things that I think might be contributing... After 5,000 miles my oil is pretty black and very low. (Time for an oil change) When I swipe my finger on the exhaust pipe, its really black but no black smoke comes out. I don't see any oil leaks outside of the engine, its actually pretty clean.
So two questions, is the low oil and black exhaust pipe normal? Why would my throttle body keep getting dirty?

Ok,I have an 05 f150 4x4 5.4. And I have noticed for a little while now that once in awhile,it seems like the front end,will shake like an up and down shake.Today it was the worse,now it only does it maybe once a week if that but usally its not too bad. Just a little shimmy. But today it really shook.Now when it happened I put on the overdrive,applied the brakes and even put 4x4 on and still did it. Now it does it the worse at very slow speeds even at crawling speed in an alley.I parked it at home and took it out again after 10 minutes and nothing! What could be causing this??

My 07 F-150 5.4 has a rough idle during a cold start for about 1 minute. It happens mostly when the weather is chilly or cold. Also after the first start it doesn't do it the rest of the day. Of coarse they can't find anything wrong and tell me there are no updates for anything like that.

I recently picked up a 2004 Mercury Mountaineer, 4.0 with 113,000 miles. OBD reader says misfire on 3 cylinders.. Installed new plug wires first.. nothing.. going to install plugs next when she is cold. Now, am I really looking at replacing the coil pack to end the misfire codes? She likes to buck and shake and idle around 400 rpms.. I know that is too low..

I have a 08 F-150 4x4 King ranch with 5.4L Duel fuel motor. Last year we were backing a trailer and the whole truck started shaking. Stopped, but it in forward and no problems, tried backing again and same thing. It did back up but shook worse with more gas.
We took it to a mechanic who said without even looking at it "Sounds like a reverse clutch, common problem" So we had them rebuild the trans, a few months later it did it again once but we were 300 miles from home. Since we could still back we did what we needed to do and drove home with no problems. Dropped it back at the mechanic who said he couldn't find anything and eventually had a yelling fight with my wife. We couldn't get it to happen again either until last week it did it again and she grabbed the camera to record it.
Took the truck back with the video, he had a mechanic look at it and said the transfer case mount bolts were loose, tightened them up which did get rid of a knock that we had since the trans rebuild and said that was the problem, it was binding and causing the shaking. This weekend did the same thing again.
Now the truck is back at the shop and only 100 miles or so left on the warranty (12m/12k). So after that long story my question is if the problem really was/is the reverse clutch or if there is something else wrong that he never fixed and was just intermittent enough that we let him get away with it this long?

I have a 2004 fx4 supercrew 4x4 , 170k miles. I bought it a few months ago and installed a 6" rough country lift and 35" tires. I noticed a little shake in the steering wheel but not too bad, just annoying. I just put on a fabtech dual steering stabilizer to remedy the problem and its much worse. What could be at fault that dual stabilizer would make it worse? I hate to just take them off, I would rather find the problem. Oh, the tires are all balanced and I had an alignment done also.

So, after putting new tires on my truck about 2 years, I noticed a slight shake when I drove at about 90kph. I let it go for quite some time thinking it was just a balance issue.
Well this weekend I spent 7 hours washing, waxing, and polishing my truck. It was worth. The rims reflect the moonlight now. It's amazing. During this washing, I scrubbed in behind the spokes of the rims. I found a big chunk of mud. Well surprise surprise, my shake at 90kph went away... or so I thought.
I no longer have the shake when driving at 90 or accelerating through 90kph like I used to. Now I have the shake when I let off the gas at 100 and drop to 80kph. It shakes at 95 through 90, and then goes away.
What is causing this? The parking brake is never used, and is showing no signs of engaging while driving. Is this a driveshaft issue?

Over the past year, I have had an issue with the front end shaking on my F150.
I have a 5 x 10 trailer. Weight capacity is roughly 2200 pounds. I hook up my trailer empty and head down the road. When I hit about 55 mph and above, the front end starts bouncing/shaking/vibrating.
Now I put a load on the trailer. Get going down the road. Hit those same speeds - no shaking/bouncing/vibrating. I have had a mechanic ride with me to check it out. First place to start, he told me, jack it up and see if anything is loose. I have not done that yet.
He has the same opinion as I do. This makes no sense. No load, shakes. Load, no shakes. You would think it would be opposite.

F150 2007 5.4 tapping from idle to infinity driver side wheel wellI have read thought a ton of these post and my head is spinning I have used 10w30 from 10,000 to 100,000 with lucas then 20w50 with lucas current 150,000 miles changed oil every 5000 +/- a few It taps when I first crank up cold or hot, it taps at 0 degrees or 200 degrees, it tapps at 800 rpms or when im really mad at 5800 rpms and never stops it is really loud at the driver side wheel well its not the injectors, coils, plugs, exhaust i have been all over, under, and around the truck hot, cold, day, night, and even threatened to empty my .45 clip on it and it refuses to tell me what is going on and cannot found a resolution I could deal with it but pulling up to the drive through window and it echoing back at me has me ready to order a create motor.

On my 2007 f150 5.4 last week i changed out the driveshaft and it smoothed things out. This past weekend I dropped the transfer case oil and refilled it with motorcraft transfer case oil as per ford but now the front end seems to shake more than before. It just seems to come through the steering wheel but the wheel seems tight almost like a death wobble with solid front axles except obviously this truck doesn't have that. There are no leaks and I filled it up to the top fill hole with between 1.5 to 2 liters of oil until it started running out. I should also mention that when i went to check the level it was overfull on the top plug but it was that way for the last 90,000 km or so.

As I'm driving down the highway my steering wheel tends to shake a little bit. My tires are fine but are offly loud . They are balanced and all but just sound loud u can hear them rolling inside the cab sounds maybe like if I had mud tires but I don't they are all terrains. . I was told maybe the bearings but I don't know.

I have an 07 F150 xl 2wd 5speed. It has a vibration/shake at about 30-45 mph no matter if its in gear or neutral, or if its under throttle or not. It also gets a little worse when breaking coming down from about 45-30mph.
I was thinking at first it was the wheels out of balance since it was only at a certain mph range but the braking thing has me thinking rotors. The truck has about 51000 miles on it.

As stated I have a 2008 F150XLT 5.4 V8. Recently it has started making a knocking noise and very rough idle when warm. It only does it when the truck has been driven slowly or typically when going through a drive through. It sounds like a rod knock but putting it in neutral and revving the engine makes it go away for a while.

I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?
