Göran W Posted September 6, 2015 Report Share Posted September 6, 2015 Not ALL codes but most....... http://jameskbeard.com/jameskbeard/Cadillac_Files/OBD_II_Codes.xls Unfortunately I don´t think You will solve it there. May just indicate that You at some time disconnected the battery? What is your problem? What is the prefix for 026? Maybe its P026 (E026) = Shorted Throttle Signal Switch PCM? is not a code. It´s a question if You want to read PCM (Powertrain Computer Module). Link to comment Share on other sites More sharing options...
brcree Posted September 6, 2015 Author Report Share Posted September 6, 2015 Thanks GW....for your input. Try-en to understand these codes...1st: when that PCM? comes up....what do I do then? 2nd. my problem was at speed my Cadi would stumble for a second or two then run ok. Starts ok, gas mileage still good. I replaced the coil inside the dist. cap today...that seemed to have cleared it up for now. Link to comment Share on other sites More sharing options...
