I am asuming you mean check engine code numbers. You will need a scan tool or if you goto autozone they will usually pull them for you. If you get the numbers and send them to me I would be happy to look them up and tell you what they are. The aldl connector should be beside the doghouse on one side or the other or under the dash on drivers side. Unfortunetly the days of retriving codes with a paper clip ended in 94

Actually, 1993 for some GM passenger cars. Like the LT1s and many 3.1L V6 FWD cars. I get calls all the time from guys trying to pull codes from those cars with a paper clip. It's pretty much plug-in proms you can, flash memory you can't.

Actually, GM started to phase in OBDII in 1994. My dad's 94 LeSabre has it.

Actually, the OBD2 style connector under the dash does not make the vehicle OBD2. 1994 LeSabres were still OBD1. The '94 & '95 GM vehicles with the newer connector do not have the class 2 data terminal and wiring. The '94 & '95 Corvettes, and 1995 F body cars all have the OBD2 style connector below the dash, but are not OBD2. Actual OBD2 GM cars and trucks came along in 1996.

You can now buy a cheap scan tool from Kragen that will read any OBD2 code and give a breakdown
on any vehicle equipt with OBD2 or you get a little nicer one from Mac tools that does the same and has
some extra features such as Web updates and comes with a cable for USB. I have the MAC one and it works great lets you also Clear the codes. Cost $100.00
