    I have this sound that comes and goes and engine shakes at idle when it does it. Any ideas. No boost leak. New plugs and wires .

    PCV valve.

    When they're new the tick like that under heavy vacuum occasionally. My new ones on the laser and talon do this.

    Thats too fast maybe to be a lifter. Definately could be something like pcv valve ball jumping around if spring is gone. Try to ear it down as it mostlikely comes outside of engine and does not sound like anything internal! It actually sounds almost like spark jumping out of wire but you allready replaced those

    Figured out my idle problem. Exhaust cam off 1 tooth. Runs like a top now.
