Looks like IACV needs cleaning. The IACV controls the amount of air intake during idling. Carbon built-up might have hindered adequate air intake.

I did short TE1 and E1 and did increase rpm. That means IACV is working.

But as you mentioned, may be needs cleaning.

Is it easy to do?

Thank you.

It is quite easy to do. I cleaned mine using throttle cleaner. The IACV opening is just *in front of* the throttle plate. Look for a little cavity and spray lots of cleaner in it until it overflows. You should see black cleaner liquid coming out. Repeat this until the cleaner liquid coming out is not too dirty.

Hope that helps.

Edit: The IACV cavity is in front of the throttle plate. *Correction per Camlex response below.*

Oh, my apologies. It should be in front of the throttle plate, as it bypasses the throttle plate during idling.

Thank you.

Yes, it worked for me. It has been 2 years and idling has been perfect since.

It's done.

Thanks,

Good to hear that. Any performance change?
