you have a vacum leak, look for a round ball with vacum lines going to it. If it is mounted on the hood make shure the vacum hose is hooked to it'the round ball(vacum Canister) might be lokated in one of the fender wells. Also the vacum line likes to fall off of the engine right where it hooks to the engine definet vacum problem.
