one bleedingyour coolant this may help but its mainly for idle purposes

two swtich the throttle body with another one or test the resistance of the throttle position sensor. that also could be possibly bad or giving the ecuthe wrongsignal...

Unplug the iacv does the same thing. still has a little idle issue just not as noticeable. try that out and let me know. my car has been doing the same exact thing. just unplug it until you find the problem instead of covering it up. it will mess with the reading for your temp sensor.
