Back again with a new adventure!
Vehicle: 1997 I30
185k miles
Idle is too low in gear with warm engine
The long story: Saturday night I finally got around to cleaning the IACV. My process consisted of dismounting the unit, taking out the three screws on the inside to remove the shield and the two on the outside to remove the motor. Then use the throttle body cleaner on a paper towel to scrub everything down (everything was coated in the grime). I removed the two solenoids and hand cleaned them (one was beyond dirty and the other shiny clean). I shined everything up and tightly reassembled the whole thing and put it back in place.
Based on the advice I've been given on the importance of cleaning the IACV, I somewhat expected a night and day difference.
I am now disappointed. vehicle idles a tiny bit higher now: 550 rpm vs the 490-500 it was averaging before.
So the question: did a miss a step with some kind of computer "Idle relearn" hoops I should have jumped through? Am I due to replace the whole IACV due to age and mileage?
