I never did think it was IAC. High,low, pulsing idle.. IAC. Have never personally seen it cause a "miss".
If it is an injector I get a dollar. LOL
But why the hell are my fuel trims showing good? I can pull a tiny vacuum line and keep my finger over most of it so it's the tiniest of holes and my fuel trim will shoot right up to 35%.
What else should I be looking at? MPG seem alright (23 mpg combined) so I wouldn't think an O2 sensor is going out. Switching seems ok.
I know you can feel the bad idle when it is still in open loop at first startup.
