My car shakes when it's on park
Also I check the idle and if I go higher it doesn't shake but if I put it back to normal it's start doing it again. Everything is new valve covers, cat system, spark plugs and wires.so what do I need to replace now...
I think I know the answer you have air leak in the idle air control unit you have spent good money on fixing your car. Take it back to where you got valve cover work done , the hoses on idle air control are either old or not put on all the way or out of order. I hope that helps . Let me know Gary [email protected]
