Thanks. I am suspecting more and more that it is the booster unit itself. Seems that when these go bad, the problems I am having can be the result. I even read that since it is associated with the vacuum lines in the engine, when the booster goes bad, the engine can rev funny or high.

I thought I was sucking down more gas than necessary, even thought it was idling high, but could not adjust it down. I'll replace the booster tonight and we'll see. The only thing left will be the calipers after this!
