    8/6/4 questions

    I don't think my 368 in my 81 Coupe Deville is working properly. According to the information center it never goes to 6, it doesn't feel like it either. Any help would be great, thanks.

    Does it switch to 4? It was a very problematic sytem, and most people have bypassed it. A service manual would tell more about how to fix it.

    I've always heard that the 6 cyl mode gives rough engine running. If yours just bypasses 6 into 4, I'd just count myself lucky...
