1992 saturn, showed code 48, I changed the knock sensor, and still had he same problem of it stalling when warm and not starting until cooling down. I was told it is probably the pcm. Anyhow, the car is now only firing on 2 cylinders (1 and 4) I am going to change out the pcm but I wonder why it only fires on 2 cylinders now. Can anyone help me out?
