Hello, I have audi 5000cs quattro 1987. Car starts and runs fine except for the following:Experienceing stumble or cutting out while climbing hills at high rpm (3~5 thousand rpm). All ignition system checks out, running premium fuel, all vac lines intact. Disconnected control pressure regulator wire conn (on left side middle of engine) and engine runs fine...no stumble. What does this indicate.
