What would cause a 1991 Grand Am LE 2.3 Quad 4 to stumble on acceleration especially when you first start the engine from?
Jzoellner
clean off the battery cables, relplace the spark plugs or replace the MAP sensor * Battery Cables- could be messing with the igniting of the gasoline witch makes your engine sloppy * Repalce Spark Plugs- not all the fuel is being combusted, if you replace with AM -Delco Rapid Fire Plugs, it should fix it or help alot * MAP sensor- most expensive, but it regulates how much fuel the engine needs so it can combust properly
