I have a problem with a slight stumble while cruising at very low throttle, especially noticeable as you reduce pedal pressure while already at low throttle. I was wondering if the control logic was such that when the TPS shows closed throttle, that the IAC becomes active even when cruising at 50 mph, which might cause a momentary lean condition followed by a rich condition as the o2 sensor responds.
