Car starts OK, but while warming up, starts hesitating, then check engine light comes on. Car is running horribly rich, tailpipe is black. Plugs, wires, fuel filter all replaced. Exhaust system including cat's all replaced. Seems fuel system related. Almost seems rich setting when cold does not adjust to warm engine?
have the same problem?
