would the tcc still mess with it if he switch to neutral? the oxygen sensor doesn't do anything till the engine coolant sensor reaches operating temp. then the "cold start" kicks off and the oxygen sensor starts working regulating how much fuel. so.... it could be a problem. why did you rebuild the throttle body?
this might help


yeah, agree with that.  I was just trying to think of posibilities and things I've seen.  thanks for the clarification on that.  plus the diag sheet.  wonderful schtuff.

I forgot to check this lol. I went to the junkyard and pulled the distributor and computer out of another Blazer. I'm going to swap each out this weekend and see what happens. I'm really thinking that it's the distributor now. I will look at the thing about the IAC valve as well
