IMMEDIATELY THE CAR STARTED TO? sound like a harley and sounding as if there was a huge misfire, i was told i might have blew to catalytic converter so i replaced that and there was no change it was then diagnosed with multiple misfires the spark plugs were then replaced along with new wires and there was still no change the exaust smells like it needs a tune up and it has a misfire does anyone have any ideas on wat could be wrong and how to fix it.
 
is the check engine light on? after the plugs and wires were changed did anybody recheck the computer codes? Are you doing the work or a professional?
