Do you have prothane motor mounts? Or window welded mounts? Solid mounts cause you to feel the vibration of the motor more.

no looks like stock mounts, just got the car, but it looks like a good sized gap in between the rubber and the edge of the mount

Cams? Check out the BS belt under those timing covers, time for some maintinence.

i also forgot to mention that when at idol for a few mintues the oil pressure gague drops to nearly nothing, but its back up to over half way while driving. is this a sign of a failing oil pump or balance shaft alignment prolbems?. i also have my timing belt covers completly off right now, and engine is in driveable condition. so tell me exactually what i should be looking for and ill easliy be able to check it out in the morning.

i would first check the balance shaft belt,, and then make sure all your timing marks line up even the one on the rear balance shaft.

Please. Please spell check.

It is normal to only have a few pounds of oil pressure at idle. A real gauge would let you know exactly how much you had.
