1991 cadillac deville starting problems
 

Hello everyone, Saturday, I put gas in my car and shortly after it started misfiring like a spark plug wire was off for example but it still had good power. When I first stared it in the morning, it didnt misfire but after a few minutes it was back to the misfiring. I put new plugs, wires, icm, and ignition coil Monday. I previously had a problem with the car not wanting to start in the morning and after awhile it would start. I replaced the ECM and that erased that problem. I pulled the codes and it erased all the codes but E41. Today the car completely died and wouldnt start again. I pulled the codes again and E27, E41, and E52. Can someone help and provide some insight?
