Please help out anywhere you can. Sorry if I sounded like I was scolding you. I did not mean to sound that way. I just meant to say you were talking TBI and he has a central port injected Vortec.

The TBI is the easiest to help with and the Vortec mess he owns is one of the worst systems to diagnose the GM ever built. I dislike this system so much that I have avoided ever owning any central port injected vehicle.

I only have a little free time that I can spend at the site right now, and any help anyone else can give is great with me.
