Ok i have changed mounts due to them being ridiculously torn i have replaced sparkplugs have done a tune up fresh fluids cleaned throttle body and yet im still have bad vibration when in drive or reverse while just sitting still any suggestions

 

You replaced all 3 mounts?

 

I have replaced all mounts i have done a complete tune up have done compression test everything seems fine but the car is still really rough at idle

 

I have a mazda with the same situation. And I replaced all mounts and it didn't solve the problem. I had a buddy check it out and he loosened all 3 mounts and then shifted vehicle from reverse to drive a few times to let the motor shift a little bit. Apparently that took care of the vibration however I haven't driven it yet to varify.

 

After motor shifted to it's new location we tightened the motor mounts back up.
