The lumina, that I have a thread on in the main (?) question forum. I was also wondering for a general question. My thought is that if I record this stuff then pull the codes, then refer to the codes, then go to the parts store and compare notes. I'll actually have something to refer to!!! I have a buddy that runs an autozone store, he hunts my land and always gives me hell about using a paperclip to pull codes. He's not a mechanic, he is a hell of a material storage specialist!!!
