Bouncing Idle

Bouncing Idle
I get a bouncing idle when shifter is in neutral or clutch pedal is down. When A/C is on it is not as prevalent or doesn't do it at all. Only happens after engine has gotten to normal operating temps. Buddy of mine suggested it might be the throttle position sensor. I just had the throttle body replaced about 4k miles ago. It did not do it right after the TB was replaced, so I don't think it is the TB unless it had an early failure. I suppose it could be a TPS. I see the numbers constantly fluctuating in my scanner for the TPS, but I think that might be due to the idle dropping below 800 rpm. Before I take it in to get looked at I thought I'd run it by the members here and see if anyone has experienced it. I did a search and I didn't see anything like what I'm experiencing.
I do not get CEL and the car never dies, just bounces the idle off the low end limiter when the rpms drop below 800. Of course if I apply a tiny bit of throttle it idles fine or if the A/C is on. That is about all the info I know at this point. Other than that the car runs fine.
