Hello.
My car is 1998 HX 2DR Automatic.
I am trying to clean the throttle and iacv to take care of rough idling problem.
Where are they? I spend manymany hoursreading many other posts, but i guess HX has a bit different lay out. It still looks confusing to me. I think throttle is located at the center top in the picture I attached. But where is iacv?
If somebody can tell me where they're located, that will be great!

I have attached a picture of my car inside.

Thank you.

A/T or M/T?

 

It's A/T. I forgot to mention. -.-

 

I believe it should be right behind the pipe/hose to the left of the throttle body.

 

you mean. here? (refer to the red arrow)

TPS is on the top of the throttle body and the iacv is on the back of it. They have the same connectors

 

Thank you very much to you all you replied. I finally located throttle and IACV, and sprayed some throttle cleaner into it. I'm gonna fire up the engine for a few minutes and reconnect the thing.
However, my idle rpm was usually 1000 - 1500. I read from this forum that the idle rpm should be650 rpm. guess I should adjust "stop screw". right?

Then.. where is the stop screw? .... questions after questions.. :-(

Thanks.

 

Hey all,

I just finished cleaning the throttle/iacv. All i could do for iacvwas to spray a few shots to the hole between throttle and iacv though.
I used have stall/fluctuate idle problem (when at stop or stop & go moment), but it was fine when I test drove it after cleaning. But still need to drive a few days to be able to actually tell if the problem was taken care of.

Anyway, I really appreciate help from you guys. hopefully this would be the last post regarding to my idle/stall problem.

Have a good weekend!
