okay found it ... its the idle air control valve ... unpluggin this item
has brought car back to fairly new performance... i still need to have
the car scanned again to see if it helped with the o2 sensor problems
(most likely since 02 sensor heater worked and it gave me proper
readings of very rich 800mv) but i still have to hunt down the part and
no place was open sat evening ... autozone can get it for me around the
end of the month
