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.

My 94 firebird v-6 has a obd1 plug but you can't read it with a paper clip. It's one of those bastard years tha you have to have a scan tool.

Bobby, it has a flash PCM, not a removable prom. Flash computers all need a scan tool or code reader. Not all flash computers are OBD2 however. Not until 1996.

Wondering why the paper clip wouldn't work.

Thanks for all the help guys........we took it to Auto Zone and they couldnt get a reading. They are not sure if their computer is the correct one for a Motor Home?

because it don't.

although some of the really early obd2 (like some of the guys are talking about) CAN be jumped but i don't remember which terminals to jump so the smoke don't get let out....96-up yer gonna need a scanner...

btw, you can pick up code readers pretty cheap, i guess, but i like a data stream...
