I am trying to see if anyone has had the problem with the engine, my problem is this, when the truck is in the idle position there is so much vibration that the passenger seat shakes. I never had this problem until I brought it in for the first tune up after that it has been all down hill.

 

Bring it back ... tell 'em to fix what they broke.... if it didn't shake before then something didn't go right..

 

I didn’t think you needed a tune-up until 100,000 miles?

 

^ My thoughts exactly... no tunes ups, just regular maintence!! Filters & Lubricants, that's it!!

 

Might be trolling; two posts, both problems.

 

My truck vibrates like crazy in idle, kinda feels like its about to die, then catches itself & revs back up. you can feel the vibes at neutral or drive, but at low idle.

 

"Engineering is aware of the concern and is currently working on a solution. Do not attempt any repairs at this time. Monitor OASIS for updates."

There's a service message about an idle vibration. I'll look for it when I get home.

 

"Engineering is aware of the concern and is currently working on a solution. Do not attempt any repairs at this time. Monitor OASIS for updates" sounds to me like we have a great truck, theres no problems at all with it.
Well, even if there is a problem, which we dont admit to, there is no fix for it, so we wont admit its a problem. I brought my truck in for over 10 things wrong with it (didnt even bother with the a/c motor noise, or a couple other things), and they found problems with 2 tires & 1 rear driveshaft. oh yeah, turned the rotors again (15k miles approx).

 

I was having some idle problems with my truck, similar to the other replies with the revving and acting like its gonna die and revving back up. It was something to do with the throttle body something called an ISA motor, could be wrong on the name, but it was around $100 parts and labor to fix. This was a rip after finding out how easy it was to replace, took the guy around 5 min. Anyway, it fixed the idle prob.

 

No, it sounds to me like what it says. They know it's a concern, but unfortunately there's only so many hours in the day, so many ideas to try, so many dollars in the corporate bank account, and so many people to work on it.

 

Why are you tuning up a 2004 F-150?

Somthing fishey about this one......
