I drive the Blazer home tonight, and it was 80% better. No black smoke,
no real hesisataion. Would stall at idle (cold or warm) but drove home okay.
No ECM codes, I think there is a slight exahaust leak on the pass. side.
Don't know if that would affect anything (other than emissions ;))
Will replace the 02 tomorrow A.M. -- hope this is the problem. Otherwise
I might pickup a new AIC(Air Idle Control) valve -- this one is old and I
may have hit it with carb cleaner -- maybe it's dead?)
