First off... what does this valve do on the bottom of the throttle body?

Then, would it be a good idea to bypass it and go straight to the IACV?

 

That other "thing" is the FITV. Not a good idea to bypass it unless you have an EMS that can control idle aside from the stock ECU.

 

what does that stand for? and ive seen people bypass it befor and it didnt change idle one bit...

Its a fast idle thermo valve I know on the newer throttle bodies it just has the inlet and outlet it doesn't have the entire setup like the older ones.

 

ic... so performance wise it wont hurt anything?

 

You'll have a shitty idle till the car warms up if you remove it. leave it on there or else youll have major problems keeping the car running when its cold.

basically it's a valve that contains thermowax that expands and contracts with the change of temperature which opens and closes a pintle that allows air to bypass the throttle body.

the idle air control valve controls idle aside from the FITV, mostly for running at operating temperatures.
