    If you cleaned the maf already the next thing I would check and clean is the IAC. They tend to get build up in them as well.

    In my 1996 this was caused by a rich tune and ended up fouling plugs.

    This is all good tech, but I leaning with Witzy. My 5.4l van is doing the same thing because of leaky injectors.

    Usually a faulty iac valve will hard start and youll have to feather the pedal to keep running but then bang...all of a sudden it snaps into an idle.

    Leaky injectors just run pitiful all around....like my van
