I recently purchased a 1992 Cadillac Fleetwood Brougham RWD with the 5.0 Chevy engine.
On the drive home car was hesitating and would only go when gas pedal floored and only start this way.
After installing new plugs, new wires, new distributor, car wouldn't start at all.
Found out to much gas is flooding replaced fuel regulator and same problem
had throttle body rebuilt and new injectors car ran for ten minutes or so then engine idle started to pick up and car eventually flooded out, also noticed catalytic converter turned red hot. Haven't tried to start again since i have to clean the plugs of excessive gas and build up each time.
I know its alot but any help
