Additionally: Every time I start the car, I have to hold the throttle a little until it warms up, or else it will die. I don't rev it up, expecially in that first instant before there's oil pressure. But just enough to hold idle, until it can hold itself. I have always suspected this is a fueling problem and unrelated to the GP problem.
