Hello. I have a 2004 Acura TL and i'm having some hesitation while accelerating and some idle fluctuation. I am thinking about changing the APP sensor and idle air control valve. I know where the APP sensor is located, but I was wondering if someone could show me where the idle air control valve is located?


Thanks!

 

wasting money if you dont make sure these parts are the cause. You'll end up with the same problem later with other parts to be replaced.

 

IACV will cause idle fluctuation, not hesitation unless the car is nearly stalling at idle.

I don't think the 04 has an IACV.
