My buddy has a 1994 XJ with a 4.0L engine,
I have tried to get the codes from the pcm by
cycling the key. I think it a 13 which is little or no
change in MAP sensor signal between key on engine off, and idle. Would a bad Map cause the engine to
not start or Idle extremly rough,
have the same problem?
