Ive cleaned my throttle body replaced my TPS. IAC is next on the list to replace.
interested in seeing what becomes of this.
i would suspect that your plugs are not the proper ones; and thinking about it, that might be my problem.
When I had this problem, a computer reset fixed it. After cleaning the iac, etc.. I had to pull the battery cables off for about 15 min, to force the computer to reset and "relearn" the " new" air/fuel curve.
