hi, this occured during some hot weather this past summer. while slowly moving(start and stop) in heavy traffic, I would notice my 87 GN stumble when coming to a stop. I scrolled SM and found my IAC compensating by rising to over 85 at idle. once driving off, these numbers would drop, but again when coming to a stop I would sense stumbling and the IAC would start to rise.
This only happened during one trip and has been fine again, but I have always been curious of the cause.
Any ideas?
many thanks
Jim
 
Tcc unlocking the converter possibly? Might be sticking.
