Low idle at stop lights, A/T

Low idle at stop lights, A/T
About two weeks ago my idle has dipped from 710 to about 610-600 while the car is in Drive. I've tweeked the idle screw on the IACV and all it seems to do is raise the base idle i.e. when the car is in neutral. I've disconnected the brown throttle position sensor while adjusting the idle but my car just does not want to idle higher then 610.
My car has 85k miles on it and in the past 6 months or so I have:
Cleaned the Throttle body
Replaced Fuel Filter
New Coils
New NGK's
The thing that worries me is my idle has dipped so low that its stalled twice now. What do you guys think might be the prob?

Warm the engine up to operating temp.
Turn off the engine.
Disconnect the TPS.
Start the engine and adjust the idle speed using the stop screw on the throttle body to 650 RPM's.
Turn off the engine.
Reconnect the TPS and restart the engine.
If the IACV is working correctly your idle should be correct. If it's a bit low, try adjusting the screw on the IACV bypass to get your idle speed to ~700 in neutral with no load. (no load means no lights or A/C)

When my car was stalling the accel would studder for a sec then drive normally but recenlty its just been idleing very low, no ecu codes. Redlines fine. Ceared the 0505 code, I'm hoping maybe something will register.

oh you know what, it might be your evap. control vaulve. i just got it fixed for having the same symptoms. my car would stall at neutral at times. get it checked out. i paid 6 bills for fixing that and getting 3 o2 sensors replaced. good luck!
