Idle high after coming to stop
Right after coming to a stop, my car will idle around 1400 rpm, climbing to 1900 rpm before settling down to 875. Takes about 5 or 6 seconds to drop. I tried the HP tuners throttle cracker table suggested by WS6FIREBIRDTA00 but it didn't seem to make any difference. Any suggestions on what to try next?

I have the same problem. The car had been dyno tuned after a cam install, but when coming to a stop after driving the revs climb for 5-6 sec and then slowly drop. I have always had that problem even when running the stock cam.
Even just revving the car, rpm seem to drop very slowly.
Could the IAC be at fault??

Each car is different. All of the follower tables on mine are set to stock values and the cracker table is actually less than the stock values. I would try and zero out the cracker table below 2200 rpms for sake of experimenting and see if that lessens the effect. If it does lessen, but still hangs, you're idle flow in gear may be too high.
