I was gonna say cam position sensor also.So the OP knows,where is a good place to get the BLACK one at?You should always carry one with you.I need to take my own advise and get one also.Another thing it could always be is the valve cover harness coming loose on the inside but I don't think thats it.It usually just runs crappy when that happens.
