If there is 0 IAC counts and air is still getting through then the IAC could be a bad or wrong part, or an unseated or bad O-ring. Use TunerPro to log MAP values and track as you try different things. FSM shows a range of 20 ? 48 kPa.

If you can't determine an IAC fault it might be worth chasing down a smoke machine, there is still a lot of oddball vacuum possibilities.

Injector O-rings could be toast at this age and injectors in general could be a good investment. Any codes?
