Yes it is (like most of you knew), OBDI. Every time I say that I want to say "OBDI Kanobee" a.k.a. "Jedi Master" (nyuk nyuk) Thanks for the links, I've already managed to read the codes using my handy dandy circuit tester (light) and aligator clip. Gotta love free code reading.
I'll do a search on the code and see what I can dig up... I'll probably end up posting again 'bout Oxygen sensors...
Thanks,
Brent
