I have a 1985 Cadillac Cimarron with a 2.0 4cyl. Engine. Only ha 94,000 miles on it, and the darn thing is flooding out when you try to start it. It dumps gas in the throttle body by the cup full. I rebuilt the preasure regulator and that's not it although the diaphram was decomposing. If I unhook the injector the engine will run untill the dumped gas in the throttle body and intake manifold is gone. My question is what else can it be aside from a 200.00 injector?
