Ok so Reg stopped by today and we looked at the IACV....I did the 9v battery thing, heard a click...we checked resistance of the valve five ohms...we have five volts with the engine running and ZERO instead of 12 with key on ...that made little sense to me but it's what the multimeter said....

From what I've read it could be the control unit...I dont know enough about the gassers to get into it. I told Reg we needed to research and referred him to a great local indie who knows the cars really well.

I was thinking what we should do, as I have done on other cars before...is remove the valve and clean it. The high idle started when we were squirting intake cleaner at the throttle body while running the engine right before an oil change. There has got to be some carbon knocked loose and chunked up on the valve right?

Well without knowing the process for removal and reinstallation of the valve...I didnt want to try. Reg has new "boots" for it...still...I told him we need to research this some more.

If anyone has suggestions on diagnosis and or can point me to the RnR procedure for that valve...much obliged.
