ok.. we have advanced & retarded the distributor advanced the throttle position and messed with the O2 sensor and the MAFS the car will start up idle *lil ruff* but then after u first rev it up when it comes back down it drops real low and starts to kick ur dummie lights on and off b/c it is idling so low and it is running REAL!!! rich

check your fuel pressure. could be a bad fuel pressure regulator if it's running THAT rich.

if your rev it, then it stalls, i would think that you have a leak in your pipes somewhere.. you are metering air that isnt getting to the motor, creating your super rich condition.

I believe the fuel pressure should actually be at about 32-35psi. At least that is what most stock vehicles run.

Other thing that will make you run rich is the coolant temp sensor. You may want to check the resistance curve on that.
