Can anyone provide engine error codes for a 1998 Winnebego Motorhome w/GM chassis Class A Vortec 454 L-29?......and the procedure for determining them? Cant find it anywhere!

Frustrated:(,

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.

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.
