Rough Idle/Vibration while driving

Asked by Oct 22, 2016 at 09:27 PM about the 2008 Chevrolet Impala LT

Question type: Maintenance & Repair

Hi guys, so about 2 weeks I overheated my car
after my serpentine belt came off and went in the
ditch. Now I am noticing a rough idle and a
vibration when going down the road. All chassis
parts seem to be good yet but my power steering
pump has been squealing whenever I turn the
wheel too fast at slow speeds. Have done a
coolant flush and replaced belt. Thanks, Brandon

Ok .chk crankshaft pulley .make sure it's kot wobbling while runNing . Also make sure all pulleys are true .didn't get bent etc. If it isn't an engine vibration od focus on the wheel/tire on the side that took the impact of the ditch . Bent wheel , tie rod etc. Also chk to see if the wheel has spots where wheel weights were lost . As far as the power steering noise make sure belt is aligned o. Pulleys properly and that a line didn't get bent pinched damaged . Good luck

Check your catalytic converter. It may be clogged due to the engine overheating and might have melted your cat converter

Converter checked out ok, all pulleys are good
