Idle problem

Over the last week I've noticed a problem with the idle in my TA. It's been smooth as silk at 700RPM since 1995. What I have noticed is that now it will randomly drop to about 500RPM and stumble a bit. If I hit the gas at this point it revs right up. Does not seem to have a stumble off idle even at 500 RPM. A couple times it's dropped and then died. Restarts fine.
Sound like the IAC or the TPS to you guys?

Thanks for the reply.
It's a '95 TA convertible. 383 with LT4 heads and intake, port matched to the BBK throttlebody. Mac headers and Y-pipe. Random Technologies high flow cat. SLP loudmouth. A4 with the 4L65-E upgrades. 3.73 gears.
I'm leaning towards it being the IAC too, but have not had a chance to pop the hood.
