If you run your car at operating temperature (radiator fans turn on, thermostat opens), the idle should be like 700-800 right?

Now if I plug the IACV inlet at the throttle body, it's still sucking. If I unplug the IACV connector, it's also still sucking. My idle with the IACV connected is 1.5k, and with the connector out it's still 1k.

The only way I can get it to idle low is by plugging the inlet with my finger. Does this means my IACV needs replacement? (Already take it off and cleaned it, makes no difference)

 

adjust the screw on the throttle body

let the car get harm, unplug the IACV and adjust the screw, turn the car off then re-set your ecu and you should be good

 

I tried adjusting the screw but it will not change. And I am guessing it's because the IACV is till open even after I unplug the wires. Does yours still sucking even if you unplug the connector?

 

im not sure, maybe you have a damaged one, they break all the time, i would try using a friends to see it it is broken or buying another one

 

Does a B16, Type R, or D series IACV fit in my GSR??

 

the b16 and ITR should fit just fine

 

before you replace it, try cleaning it out with carb cleaner. Spray in the screen and inside it. Tap out all the black stuff out. It should help

 

I already did, but still having the same problem. Thanks for the suggestion though.

 

Have you tried spraying it with carb cleaner through the inlet in the throttle body while the car is running?
