air valve on my 4runner??????
------"Sounds like a dirty idle air solenoid, or a Throttle Position Sensor out of adjustment.
if the egr valve is slow to close, that could cause the problem you're describing
throttle dashpot and/or air flow meter could cause a problem such as this too- throttle closes too quickly, afm closes fully (due to inertia in the vane) and has trouble re-opening to the proper angle."------
So I checked everything out. Dashpot and VCV are good. TPS is good. Ran some troubleshooting and decided it's the air valve. According to what I read to test that when I turn the idle screw in all the way when the engine is cold it's supposed to lose rpms but if I turn it in all the way when it's warm the idle shouldn't move. Well when I started turning the idle screw with the motor warm it immediately started to lose rpms. So according to the repair manual I have a bad air valve.
The only problem I have is that I can't find it. The manual does not say where it is. There is a picture but see nothing like it. If anyone might know where the air valve is that would be awesome. I have a feeling it's goin to be on the back side of the motor along the firewall...the only place I can't see. I did adjust the idle and it helped my problem a little bit. It still lost rpms comin to a stop but only got down to about 600. As of now that's good enough for me. Thanks for all the suggestions.

The idle air controller is made into the throttle body.It works off of water temp only.Any time you turn the idle screw it will change RPM.Just in case"you need to check the A/C idle up air valve.It should only activate when the A/C is on and idle the engine up.It is adjustable.Check it and holler back.
