Well i did do the injectors as a replacement early on to attempt to resolve this problem. I didnt see any difference in the idle problem. I have observed the following :
-the voltage "open loop" when i remove the ICV from the ICU circuit is unstable and moving around 1.25 volts.
-when i remove the connector from the ICV with the engine running there is no idle difference.
-When i turn on the compressor there is noticeble DECREASE in idle speed from about 800 to 550 rpm indicated.
-With KOEO the voltage at the ICV is 1.25 volts and i cannot hear the classic click.

I am starting to conclude the ICU is bad or at least a very bad actor. Is there any further way I can reconcil the ICU vs the ICV???How about removing the connector from the ICV once the engine is started and put battery voltage on it to see if that chnges the idle???

Thanks.
