Im wondering if the power steering pulley is the cause of the misfire i replaced the coil spark and injector and same problem, engine is quite at idle at low rpm and heavy load CEL starts flashing currently CEL is on and hitting p0303,juat replaced alternator and noticed power steering pully had a wobble when I shook it would this cause a jump in the belt and cause the ecm to misinterpret a misfire hoping im.not looking at cams and lifter before I go to dealership for diagnostic
