I normally don't run with the AC on as I like to drive with the windows down. But I turned it on the other day and the revs never went up during idle, so I figured it was a dirty IACV. I took it out, cleaned it out and put it back. Car seems to idle better but when turning the AC on, the rev's do nothing (they just stay normal), but I do see a change in my idle AF (leaner). Any suggestions?
