Hello all,
I have a constant vibration throughout the entire car that's driving me crazy. It happens while idling & gets worse once you put it in gear & get high into the RPM's. When its nice out its not as bad as when it rains. Once its really wet out the vibration gets a lot worse & resonates throughout the entire cabin even at low RPM's.
Any ideas???

 

Is the only symptom the vibration? Are there any noises? Any check engine lights etc...

 

No lights & the car feels fine. I did have 2 recently but they were completely unrelated. About 3 months ago my front O2 sensor went & 2 days ago one of the EGR vacuum hoses behind the throttle body popprd off. Fixed both times & light went away. No other codes thrown.
Revs do seem to hang a bit the higher I rev but I don't think that has anything to do with the vibration.

 

Do you have aftermarket motor mounts? When you shift at high rpm, do you feel the car kinda rock forward and back, or any clunking noises?

 

I did change the front mount but the vibration started a few months after I installed it.

 

Try shaking the motor back and forth with your hands while looking down at the engine bay. Make sure all the bolts are still in the mount/cross member. I have had bolts shake lose before from not tightening enough.

 

ok, I will gove that a shot. Any other suggestions? I kind of feel like it could be caused by the exhaust. I don't have a jack anymore & am going to go to a friends house this weekend & get under the car.

 

I don't know about exhaust. I broke a hanger once unloading off a trailer in one of my Civic's before. Anytime you sat in the car you could hear it sqeak as it shifted. I guess you could grab your exhaust from the rear and give it a shake. Only real way I see the exhaust causing a vibration is if it rubbed against the car.

 

Check your drive shaft carrier Bearing

 

Unload your suspension, you should be able to narrow it down.

Would that cause vibration in neutral?

 

What do you mean, get the car in the air? I don't see how that helps since the car vibrates even when parked in neutral idling.

Probably not too much of help but my old exhaust hangers were worn out and would clink against my drive shaft. When it was nicer out it wouldn't do it as much, but as soon as it rained it got super bad. It wasn't so much a vibration more of a grinding

 

I feel like its exhaust related but I just haven't had a chance to get the car in the air yet. Regardless I think it has to be something under the car causing the vibration.
