I haven't got a clue. I've never done much work on computer controlled cars. I also have an 89 IROC L98. So, I guess it'* time to learn how to pull codes and so on.

Sorry for the dumb question if it'* been asked 20 times a day.

we need to know what year u have, why dont u put some info on ur car in ur sig, if ur lucky, and u have a 93 and ur ses light works, then u might not need a tool to get codes

Sorry about that. I have a 95 Bonnie SE, stock.

u need a scan tool or code reader that can read obd1 vehicles

I think '95 was their test dummy for obdII though. I think it was in the later part of the year they had obdII but at the beginning they had obdI and I think I remember hearing an obdI with and obdII connection haha. Will could answer this better, he'* the OBD guy OBD OBD OBD OBD

That clears things up.

Hey thats what I'm here for. Just remember that if your obdI connection should be obdI but looks obdII that doesn't always mean that you have an obdII computer. You may have gotten their test obdII connection and still have an obdI computer. It could have gone the other way too, GM guys are weird. They sell scantools for obdII that have an obdI connection on them for this, just incase your obdII computer has an obdI connection. Its pretty easy to tell if you have obdI or obdII, but like I said will would have to answer that. Ahhh the wonders of obdI and obdII

Furthermore, obd obd obd obd
