I'm trying to diagnose a cold engine low rpm hesitation issue under load (acceleration).
To rule out the IAC, I've completed an ohm test on the IAC pins, they check out fine according to the FSM. I'm not able to remove the IAC at the moment, but I have live from the TOYOBD1 app. I get data from the IAC, starting at 29% when the engine is cold and decreasing to 12% when the engine gets to full operating temp, at which time the hesitation is not noticeable anymore.
Based on the data from the app, would this indicate that the plugger is moving, and would this be a substitute for an IAC volt test to test plugger movement?
