Hello guys, I have search on the forum for an IACV, but can't seem to find on the 2GS400' 98 model. I would like to locate where is it on my engine? I try the Sewell site to pull up the part, but the picture is awful to tell. Can someone be kind enouth to take a snap shot of the Idle Air Control Valve, pls? I would like to clean mine. I'm having a low idle and don't want to replace it, if I can improve just by cleaning it. Thank you in advance folks.

 

Try cleaning your throttle body with some carb cleaner and a rag. I cleaned mine a couple weeks ago and my idle got really smoother.

 

i did clean mine as well, however, it still gets a little low idle. So may be I am thinking of cleaning out the idle air control valve which might be improve it a bit. Just don't know where it locates on the engine. Thank you for helping out.

 

There is no IAC. These have a electronic throttle by wire throttle body. Idle control functions(IAC), cruise and control, traction control is all controlled through that 1 throttle plate. If your idle is around 600-700 rpm then that's normal. If you're really concerned, kicking on the AC will raise the idle by 50-100rpms or so.

 

Thank you JeffTsai, I am now can relax a bit better. I thought my GS is eating my pocket once again. Thanks.
