How do you set minimum air? I don't think I've done that.
Dynomite- I've got all of Jerry's parts for the PCV system- they are great. The old parts just kind of stretched/fell apart in my hands.

IAC counts for idle need to measured at 80+C, closed loop. .5v is a little low for TPS. I set mine at .53-.55v. The TPS needs to be, at minimum, re-checked and possibly re-set after each time you set throttle opening.
Min Air must be set so that the motor idles just under the point where it does not require IAC opening. You'd like to have IAC counts 10-15 at operating temps and idle. I set the throttle opening with fans running, putting an additional load on.
You can do a search on Min Air adjustment. I posted a step by step procedure for doing that. The set screw for throttle opening should be replaced by a hex bolt which would allow you to change throttle opening w the motor running.
