The whole car vibrates kind of like a diesel. It vibrates while parked so I am not sure what it could be. I have not had the time to go out and look at it. Working two jobs right now and dont have the time at the moment to get under the hood. I am going to try to get under the hood this weekend since I took some time off. However, I remember back in the day when I was a kid rolling a honda civic I did a engine swap and did not put the cat back exhaust on for the test drive because I wanted to make sure the engine was running fine but I did put the header and downpipe on and what not but it vibrates almost the same as it did when I had the exhaust off of my civic. As the engine got higher in RPM's the more the car vibrates. I am seriously thinking it is a mount. I just could not think of what else it could be.

 

Dang, I dont want to drop a lot of jack to find out what is wrong with the car. Surprising no one else has had this problem in the past.

 

I just jack up my car and look around under the car since the top mount was ok. It was the bottom mount. The bolt fell out. Surprising to see that. But that was the loud noise and that is why it is vibrating. Going tomorrow to the dealer to buy another bolt.

 

wow that took you forever to get to.. i would have crawling around under there in the middle of the night when it happened looking for the problem.

 

Just parked it and drove another car. The more I drive the car the more problems come up.
