From previous thead

1/15/08 Ok I replaced the plugs, wires, PVC, and power pack. I am still getting the P0302 code and the engine idles very rough, sounds like its losing a cyl and only idling on 3 cyl. when I'm driving theres no problem but at a stop light or sign it idles rough, any other suggestions anyone ????

Sounds like a vacuum leak. Start at the vacuum source i.e. plenum pinching off hoses until the idle settles down. Then, back track to it's source.
