Phillip Posted February 28, 2004 Report Share Posted February 28, 2004 I am on the road with my 96 STS and the car started to run a little rough. The Service Engine light did not come on but I searched and found the following two codes in history: AC1313 and TC0073. I don't have my book with me. Can anyone tell me what these coded mean and if they could cause the engine to run rough. It feels like it is missing. Thanks, Phillip Link to comment Share on other sites More sharing options...
ranebeen Posted February 28, 2004 Report Share Posted February 28, 2004 Can't help you with the codes, but sounds like you either have a vaccum hose off or bad plug or plug wire. Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted February 28, 2004 Report Share Posted February 28, 2004 Don't forget the how-to section at http://www.caddyinfo.com/howto.html but I don't see AC1313 anywhere. The TZ is a traction control interface; I used to get that whenever my traction control came on on my 96.
