Gary;
        All those are good possibilities. Also check for vacuum leaks.
This subject includes a lot of areas. While the problem is present, pinch
of the crankcase breather hose( making sure the hose is not rotted and
cracked, mine was). If it quits let me know. If not I would then check
the throttle body alignments outlined in the Bentley, very critical. I
would also remove the ISV(idle stabilizer valve) and flush it out with
throttle body cleaner i.e. safe for O2 sensors etc..
        If after all that and still no go then write me back and I will
share one of the "Secrets of the Inner Circle"; How to adjust the ISV!!

Drive Safely & Good Luck
