    1991 Sedan Deville

    I own a 1991 Cadillac Sedan Deville and I am having several problems with my gas. I give the car a lot of gas and it barely goes.... It also chugs, backfires, and dies out. Anyone out there have similar issues?

    Let's move this from the chit-chat Lounge (non-specific posts only) to the proper Deville forum.

    I am going to probably take it to a shop today. I do some light Auto mechanic work but I am not a professional... Thanks for the advice...

    Start by pulling your codes.

    Go to the top of the FED Deville/Fleetwood page, and read the "sticky" thread on how to pull DTCs. Lost any codes you may find, AND THEIR DEFINITIONS, here (there's a link to code definitions within the sticky).

    Low fuel pressure and a clogged car are possibilities that won't set a code.
