has anyone replaced their motor mounts?

[starfox86]

I first thought I was having trans trouble with hard shifts. I now think I have a motor mount shot because when I rev the car to 3000rpm the entire car shake side to side because of engine movement. Does anyone have any experience doing a motor mount replacement?

The engine shouldn't shake at 3000 RPM, least enough to shake the entire car, even with a busted motor mount.

From your description, I think you have other issues there. Coils is at the top of my list.

Do you have a gen2 ls and it is just hitting the neutral/park rev limit and making the motor shake?

All the coils are new.

I meant like when it hits the rev limiter and bounces off of it when holding the throttle in park, the car shakes wayy more than it used to.

Gen II doesn't shake when it hits the limiter. Gen I does.
(Gen II just doesn't open the throttle enough to go faster when it hits the limit. Gen I doesn't have throttle control, so it has to start cutting off fuel injectors. This causes the engine to miss/shake.)
