I got thisn done the other day. The IAC still wants to set at 39 until I trick it, I can pull pressure on my shifter without taking it out of park and it thinks it in drive, then the IAC will start to drop. Nothing seems to make the IAC drop after its started at normal temp, this is not a big prob for me tho. Kickdown steps ive heard should be less then the IAC position vs coolant table but its not, Position vs coolant is at 12 and the kickdown is at 25 tho reducing it dont seem to make a difference other then idling higher. how should kickdown be set?
