What Would Cause My 1990 Brougham To Run Rich? It Has A 5.7l Under The Hood. I Have Changed The Coil And Performed A Full Tune-up. I Tested The Volts Form The Battery And The Alternator. The Battery Is At 13.9v. I Read That It Should Be Around 14.2. Would This Make The Car Run Rich? Also I Am Experiencing The Shudder Every Once In Awile And The Stalling In Reverse That Dopestar Was Experiencing. When I Did The Tune-up I Did Not Gap The Plugs. I Am Assuming This Would Not Cause That. Thanks In Advance For The Info.

check your timing

if that doesnt help anything, replace your coolant temp sensor on top of the intake manifold at the front right next to the thermostat, and the oxygen sensor.
