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.

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 2007 F150 (2wd) with 80k. My truck recently was vibrating under braking so i took it to my mechanic to have the brakes fixed. All the rotors needed to be replaced. In doing so, the front rotors were changed out with the kit that converts the front rotor/bearing assembly into two separate pieces to cut down on maintenance costs in the future. With this being said, after getting this work done, the truck didn't vibrate anymore... that is until i got it out on the highway. Now the truck vibrates from about 45-50 and 70-80 pretty bad. The steering wheel shakes back and forth too. I have gotten the tires balanced in hopes to fix this problem which it didnt. What could this problem be?

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.
Ford F-150 (2004-2008) :: Rough Idle And Hard Miss Under Load - CEL Code P0306
2005 f150 5.4.
I have a slightly rough idle and can feel a miss at 1600 to 2000 RPM. Sometimes running about 65 MPH up a slight grade I can slowly press the gas pedal and the engine will begin to miss much worse, causing the truck to shake pretty bad. When it gets this bad it will slowly flash the CEL and I get a P0306 code (Cyl 6 missfire).
The truck has 148000 Miles on it and the plugs were replaced at approx 120000 by the dealer.
In the last week I have replaced the plug in cylinder 6 (looked ok) and have replaced all the COP's along with the fuel filter and the injector on #6.
I haven't been able to get it flash the CEL light or throw a code since replacing the COPs though and I am at a loss at to what to try next.
Ford F-150 (2004-2008) :: 2005 - Rattle And Vibration At Idle Only Occurs With The Truck In Gear And Stopped
My F-150 has developed a rattle and vibration at idle that only occurs with the truck in gear and stopped (with the brake depressed.) The noise appears to be coming from the front of the truck, perhaps from the driver's side (though it's difficult to tell while sitting in the cab).
Before I go crawling around underneath with my son holding the brake while the truck is in drive--I would sure like to know where it might be best to point the flashlight.
Ford F-150 (2004-2008) :: 2007 - Rear Driveline Vibration At All Speeds
On my 07' I bought it home mid AUG. It has been getting much worse to a point there is a rear driveline vibration at all speeds above 40 and up to 70. I used to change intensity whether you are on or off the gas, and would almost vanish if in neutral. However now it is all the time.
I cannot feel any play on the u-joints, the yoke has a little play in the xfer case but is is normal like on most other trucks I have owned, and the pinion flange is nice and tight. Could this be **tight** ujoints or the driveshaft itself? It looks rusty, but there are no dents on it.
Ford F-150 (2004-2008) :: 2007 - Vibration And Noise At Highway Speeds
First, details about my truck. 2007 F150 SuperCrew, 2wd, 5.4, 203,xxx miles on it, leveled with Hell Bent Steel 2.5" kit last year, has been aligned professionally since then, tires are good and balanced.
The issue I have is a vibration, kind of the same feeling when driving on a road surface that has had the top level of asphalt removed before it's resurfaced. It's mostly noticable at highway speeds. Its not a violent type vibration, but you can feel it. There is also a sound, similar to tires with a deep off road type tread.
The sound and vibration more noticeable when making lane changes or when wheel turned towards left, at highway speeds, not as much to the right. I've checked front wheel bearings, they are good, zero play, no loose suspension parts, u-joints are good, no leaks anywhere.
Since it makes the noise and vibration a bit more when moving wheel, could it be a power steering pump? The pump is the original.
Ford F-150 (2004-2008) :: Slight Vibration At Idle / Fluid In Power Steering Reservoir Shaking Back And Forth
My truck had a slight vibration at idle today and what i noticed the most was i was looking at the top of the motor and i noticed that the fluid in the power steering reservoir was shaking back and forth like i was shaking the container. Is this from the vibration or is the power steering system vibrating. I have had this truck for two weeks and it has 135k on it. It is the 5.4 motor...

View 2 RepliesFord F-150 (2004-2008) :: 2007 Won't Run / Engine Would Shake At Idle When Hot
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...
Ford F-150 (2004-2008) :: 2007 - Cam Phaser Noise At Idle When Hot
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....

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.

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.

View 6 RepliesLexus ES 2007-12 :: Pulling To The Right And Steering Vibration When Accelerating Hard?
I have a 2010 Lexus Es350, and I am having this issue:
When accelerating hard, the car will aggressively drift to the right. During normal driving it is otherwise fine.
When braking from 60-70mph, I will also get a significant vibration in the steering wheel.
What can be the issue here? I've read possible brake rotor, tire out of balance, alignment?
Are these 2 issues connected?

View 4 RepliesIS F (2008-2014) :: Strange Vibration When Car Is On Idle
I've had my ISF for about 3 to 4 months. I absolutely love the car and i haven't seen too many of them in this area (central NJ). I wonder why lexus hasn't done a better job of informing the public. Most people don't even know that lexus makes a V8 sports car.
When the car is on idle, there is this strange vibration that i feel coming from under the seat. It happens for a few seconds and then stops and starts again when the car is on idle. It happens when the car is not warmed up, but also when the car is properly warmed up. I'm not sure if its a cause for concern. Is it because of the timing belt? Engine? Just want to make sure its normal and have the car looked at if its not.
