89 929 Occasional Stall

[older929]

Hi All,

My 89 929 w/102K miles suddenly has started to stall a bit. Generally only a couple of times a day when coming to a stop. Idle seems to low and leaving the A/C on will prevent the stalling condition. Does this sound like an IAC issue? Propane gas poke around didn't seem to find any kind of intake leaks. Is the IAC prone to having problems after a while?
Thanks,

had that issue when my Throttle Body Boot (big black hose between VAF and T cracked and started sucking in un-meetered air.
