Volks,

The saga continues. 

tested coolant tempII  sensor, and it is in line.
replaced oxygen sensor..........same result
when warmed up, it would hold idle about 850-900 rpm.

I checked rubber boot from AFM to throttle body, it is fine(actually took it off)
;ooked for other vac leaks none present

Switched on A/c car died.  

When i turn the idle adjustment screw on the throttle body NOTHING happens..whether i go all the way in OR all the way out....idle is the same.

This is truly bizarre.......

When key is first turned, i can hear the idle stabilizer valve kick in.  (Buzz)  

I am going to check (recheck) valve adjustment right now
