Laz this is the thing i bought

 

ur just all over the forum tonight

 

whose all over the forums??

 

the "black thing" on the back of the throttle body with a 3 pin plug is your TPS (throttle position sensor)

 

and i was talkin about the ICV AND THE Fast Idle Thermo Valve whats the difference between them

 

FITV is mechanical, IACV is electrical. FITV is used during cold starts or until the coolant is hot enough to make the wax pellet expand enough to seal off the air passage into the intake manifold. The IACV is then used by the ECU to control the idle.

maybe you should be a little more specific then "black looking 1"

SORRY MASTER I COULDN'T REMEMBER THE NAME WHEN I WROTE IT LOL lmFAO so what happens if you take the FAST IDLE THERMO VALVE OFF will the car still be able to idle ?

im reffering to this thread https://honda-tech.com/zerothread/1657104

 

If you take it off, you won't have the additional air flow that it was providing during cold starts. So really the question is: How cold can it be where FITV operation isn't really needed? And in that thread, one guy states "If you're living in CA, you won't need it", so there's an answer. I'd say if you're living up north, you'd need it.

So yes, with the FITV off the car, it will still be able to idle just fine when warmed up since the FITV is basically disabled. It's cold idle operation that will be effected.

 

k so when the car is cold it'll basically idle like **** correct ?

 

Yep. And if happens to not idle at all in the cold (when starting up), well, you've got a potential reason.

 

yea thats what i figured because i saw people selling this block off plate or w.e but from what i had heard was that the fitv was the one that handled the idle during start and when the car was hot then the iacv took over so without the fitv the car should not idle at all during cold it should go crazy
