I had a suggestion from Marc Haibeck that it could be the PCV grommet for the valves. I checked that today and it was ziptied to the tops of the PCV valves. Is there anyway to pressure test that system?

Another thing I noticed today. If the AC is on the idle is pretty much perfect. It doesn't fluctuate at all. Is that normal? Could this all be IAC related?
