Cadillac Repair: 1989 Cadallac Fleetwood, cadallac, catalitic converter


Question
QUESTION: The car bogs down, backfires, then goes great for a little way and the whole things starts over. We can't seem to get a code to come up. We have just changed to fuel pump but no luck. Someone suggested to stepper motor. I have no clue what that is or if it could help. Desperate and frustrated.  Carol

ANSWER: Do you know how to access the computer in order to retrieve the codes ?.

By chance did this problem start soon after you put gas in the car ?.



---------- FOLLOW-UP ----------

QUESTION: the codes I got were code 52 abd cide 63. We have done a full tune up, replaced the catalitic converter, replaced all the fuel filters, replace the egr valve, replaced the distributor cap. I don't recall that it has made a difference when I fuel the car.

Answer
Is this a front or rear wheel drive vehicle ?.

Where did you see the letters abd and cide ?

E52 = either the battery was disconnected OR there is a wiring fault at the ECM computer or a faulty computer OR a faulty ground circuit going to the ECM.

E63 = happens when you set the cruise lets say at 60 mph and you go to pass a car and you exceed 20 mph over the original set speed of 60 mph. All that needs to be done is to clear the code from the computer.
