the engine warning light has been coming on. I took the car to Auto Zone to see what the error was. They were unable to get any reading from their hand held device. Is the only way to get a read out of the problem is to go to a dealer? This engine light will turn off on its own and while driving pop up.

no, you dont need a dealer. take it to a shop and have them check it out for you. they can retrieve the code, do a proper diag and give you a bid for repair. Roy
engine light just came on
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
After driving and running errands turned on cadillac to have the engine light come on and the message board to read Reduced Engine Power - could not get the cadillac to go over 35mph
Check engine light comes on when the gas tank is below 1/2. Replaced gas cap and that seemed to help for awhile, but its doing it again? Any ideas?
Compressor quit working, going to get a scan to reveal codes, any ideas or what to look for once I have the code? Leak? Locked UP? looking for ideas or someone who has had the same issue
