Question
Hello
My 93 Cadilliac sedan deville 4.9FI cut off this morning on the highway, I put the car in (N) and tried 2 restart it,it didnt. I pulled off the road and a few moments later it started up. How do i find the problem ? No one can find the on board disgnostic port.

Answer
IS or HAS the CHECK ENGINE light ever illuminated while driving the vehicle and or has any other lights illuminated or any messages from the message display center ?.


You do NOT get the fault CODES from the diagnostic connector. You get them via the climate control panel.
