i have a 2000 impala and my crank shaft pulley is wobley and im getting the p0306 code and was wondering if i can take my pulley off and jus put it back on there straight or do i have to buy a new one? thanks guys

 

First check to see if the bolt that hold the pulley in place is tight. Then check for any dirt or debris around the belt or pulley..

I wouldn't run the car too much until you diagnose this problem, if the crankshaft pulley wobble constantly it can cause damage to the crankshaft itself

 

depends how wobbley...some crank pulleys give the illusion that they're wobbling. The cyl 6 misfire code probably isnt related
