I thought I would have fixed the problem when I had brand new motor mounts installed, but that's not the case here......
5 speed GT vibrates and grumbles under heavy acceleration, but not until it hits almost redline. Runs great up to that point and then grrrrrr, rumble!!!

Naturally, I just assumed it was the motor mounts and had them replaced accordingly. My tech showed me the old mounts afterwards and they were definitely toast. The car revs perfectly now and is as smooth as a new car until the same exact point it shuttered at before. In the last 1000 RPM's, it does it's thing. I didn't get the car back until last Friday and now unfortunately my tech is on vacation until a week from tomorrow. So I haven't discussed this with him yet. So I won't have to speculate until then, I was hoping someone on here may have encountered the same situation as this before. This is a first for me, as it's usually always the mounts.
Anybody, anyone, Bueler?
Thanks, Todd
