#112 of 182 Re: 2006 F-150 Vibration worse when towing [tdmadmac]

we too have a new F150 STX bought in August 08. Since then it has been in the shop for almost a month. It has had 14 new tires of different brands, new rotors, new drive shaft, and no difference. The Ford engineer said it was not fixable to our service manager. Then he told the Division person it was in an "acceptable" range. How is it acceptable when at high speeds it shakes enough to mix a drink and when you go over a rough spot the front end feels light and out of control.
We also drove 3 more F-150 2008 an 2009 and they were worse than ours.
Ford now will not do any more to fix the problem.
Have you thought anymore about a class action suit? Our Service manager said he will support us with documentation.

Did replacing the coils and plugs fix your problem?
I have an '04 F150 4.6L with almost 70K miles that has a rough idle while sitting still, and has intermittent (though frequent) misses while lightly accelerating and then after I have leveled off to maintain a constant speed.
It is getting a little worse each day.
I had it hooked up to a diagnostic machine at a local auto parts store that read a misfire on cyclinder 2.
I had the fuel system professionally cleaned, air filter changed, oil changed, and it still is doing it.
I was just wondering if you got your problem fixed because it sounds the same as mine.

I haven't quite got to that yet, I am going to try another fix, I was told it could be the torque convertor clutch and I have disconnected my battery to reset the computer and it seemed to run fine the first time out, but went back to it's old trick on the second run so I am going to try it with the overdrive off and see if it still does it, if not it is likely tranny related if it still does I will be doing coils and plugs. I will post as soon as I have a fix for my problem.

You can add other owner with issues on the vibration. 18k miles I asked the dealer what the issue is and they said it was a #5 injector issue??? Not covered under warrenty. At 45k broght it to another dealship he said the same thing. Several months ago I recieved a letter from ford saying they are having issues with #5 injectors and to have it check...LOST THE Letter. Did anyone else get a similar letter?
Transmission also slips on hills at 20k they said nothing is wrong. I love fords but this may be my last.

has a 2005 f150 4X4 it was starting rough then after moving and getting hot enough starts to hesitate and stall, it has 73000 miles . Has changed the fuel filter and checked all the coils and plus for spark and they all seem to do fine. Fuel pump is pumping but engine will not start at all now ,.. when first turn it over will attempt to start but will not catch for the lack of a better phrase, had it checked by a local mechanic when the engine light came on the first time and the codes showed a tcp or a t and p stuck open and stuck closed along with forced idle. has anyone else had this problem?

#119 of 182 2006 Lincoln Mark LT vibration
Jan 16, 2009 (8:53 am)
I have the 5.4 liter in my lincoln with 30,000 miles and there is a vibration in it when the motor is under stress mainly between 40 to 60 miles per hour. I have had the dealership looking at it for a month now and had said something about the torque convertor and ford has had problems. Well they been replacing everything but the torque convertor and it seems to be getting worst. I think it is a problem with the 5.4 or transmission. They also had said that it was within tolerance,I've had about every ford truck out and never felt this before

Yes, I have the exact same problem from 40 up to 60. 70 to 80 runs smooth.The dealer ship also tried body dampeners on mine that didn't help
Jan 19, 2009 (2:51 pm)
Just had the same problem with mine. They are now replacing the entire engine. They said the cause was the two cam phasers and there was also a bent rod.
