I have an 87 na. There is a vibration coming from the engine when I rev over 4000 rpms. First I thought in my drivetrain but it vibrates with the clutch drepressed also when I rev the engine. It just started doing this. Engine was smooth as silk. The vibrations cause everything in the center console to vibrate immensely. Also if vibrates under decelerations when I am shifting down.

Anybody experience this before or have any ideas?

thanks

Probably a motor mount too. Especially if you've been driving hard
