[ToyotaKilla]

I have a 92 Eclipse GS when i start it i hear a weird screech from the engine bay. I think it might be the alt. belt but not sure. Also the car kinda shakes when it is idlen. Help please

yeah sounds like a belt. check the tension and condition of your serpentine belt.

As for the shaking, at idle what is rpm?
