REnder

When I'm gunning it there seems to be alot of vibration when I get a little past 4k RPM. Is this normal?

ha ha, I don't think so...

Does it do it in neutral? If so, it could be a broken motor mount. (my car had a similar problem and I discovered a broken mount).

I don't rember but I don't think so. I hope its just a broken motor mount.

I'd say go out and drive it, then come back with a little more specific info. Does it do it in all gears? in neutral? when the car is fully warmed up? Does the car shake (suspension/tires/steering rack), or just the motor? Are there any strange noises? ummm, can you *slowly* accelerate and try and pinpoint the EXACT RPM's it shakes at (from what to what). Ya' know.

why not? probbaly the cheapest thing to fix LOL...

if you still have the stock fan. take it off and go for a very short drive. somewhere where you won't have to stop. see if it goes away

Had similar prob with mine, & turned out to be a very bad rear trans mount. If you can move it sided to side, wiggle it whatever....more than likely that's it.
