My 1985 C4 runs super rich since ive had it for a few months now. I'm kinda new to working on it so I've basically thrown everything but the kitchen sink at it with a tune up and new fuel system components. I just put in a new fuel pressure regulator because I had fuel in my oil and thought that might be the culprit. SInce I've added the new regulator and an oil change, it still runs rich and falls flat on it's face on WOT. I have not yet tested or replaced my O2 sensors, is this the next logical step? Am I missing something simple here?
