kushmastercain Posted February 21, 2011 Author Share Posted February 21, 2011 just replaced all the plugs and wires. if my timing belt was off wouldnt it miss all the time not when its just sitting in park idling? Link to comment Share on other sites More sharing options...
johnegg Posted February 21, 2011 Share Posted February 21, 2011 no, they can run ruff at idle and smooth out at speed. pull your cam covers and see if both sides match. 2 or 3 screws per side. easy check, but no guarantee. what kind of plugs and wires did you use.?
