Hey guys. 1997 Mitsubishi Eclipse with the 420A / 5 speed. Had an issue start last month that has been driving me nuts. Noticed my crank pulley was making noise at around 2-2500 RPMs. it'll make kinda of a "shh shh shh" noise, at these RPMs. It was very loud, so last weekend I finally decided to buy a new crank pulley and replace it.

New crank pulley on, everything back together, and I still have the noise at 2-2500 RPMS. And on top of that, I decided to pop my hood and look at the crank pulley while the engine was idling, and it seems to be wobbling slightly, but a rev (or any constant throttle above idle) and the wobble stops. Not sure whats wrong?? any help or insight would be appreciated. Thanks guys!
