My 1991 Caprice will fire up every morning no problem. Runs great for 20-30 mins or it eems until the engine warms. Then the car will shut off, but will fire right back up. It will idle all day as long as you don't give it gas. The car has plenty of power. You can put it in any gear and it won't cut off until you let off the gas. Sometimes I have to drive it with my foot on the brake and gas. Troble codes are for map sensor, knock sensor, coolant temp sensor, and air intake temp sensor. Replaced wires, plugs, fuel filter, coolant temp sensor, and cleaned injectors. What could this be?
