Around 700 RPM and 2500 RPM and above the car seems to shake a lot. It is very noticeable. With the engine idling I looked under the hood and the engine itself was shaking as well. I thought it may have been a poor spark from the distributor but after replacing the cap and rotor, the problem was still there. I also noticed that the distributor was shaking a lot when the car was running. Any thoughts on what the problem may be because I'm stumped. The only other thing I could think of is maybe an engine mount bolt is loose.

 

I know it's a pain in the a** on an l98, but have you checked the plugs? Maybe you fouled a couple?

 

I've haven't had time to check the plugs yet. Once all this rain stop I'll check it out. Anything else I can do in the mean time?
