Question about 1992 Chevrolet Lumina APV
Run good until engine warms up,then engine starts cutting out,bacfires,and catlatic converter gets cherry red hot
First thing i would check would be the mass air sensor. Sounds like its running rich after it goes into closed loop fuel. In open loop it has preset values and are based on the temp sensor. Then either run on the map sensor or mass air which everone it has.
