About a year ago I bought a '98 5.9L and it has ran like a champ. Last January I hit a mailbox. Anyways I finally got around to getting my front bumper and grille replaced, while I was at it I got my car aligned and my front left wheel bearing replaced as well.
Got my car back from the shop and it vibrated since I turned the engine on--really really bad. It feels as if the motor has no oil, but it does and the pressure is good as well, or a broken motor mount. But I did a visual inspection and all the mounts seem to be fine.
I turned it off going down a hill in neutral and it was smooth as glass, but as soon as I turned the beast back on just went to ****. Of course I called the shop all pissed off but they claim nothing they did would affect that, and that it didn't drive that great when I took it there--oh but it did.
Anyways does anybody have any ideas? Would be extremely appreciated!
