In my last few posts I had wrote about my car being stumbly and pretty much not being able to take off with the a/c on etc etc. All leads said I should try cleaning my IACV, So this morning I pulled it off, cleaned it real good and put everything back, Now my car drives great with the a/c on, But now I have the famous pulsing idle That just goes up and down, even after clearing the ecu and letting it warm up. So what does this mean, whats next on the list for my new car? lol

good luck

 

Thanks, got some more stuff to try tomorrow, I switched out to my friends ecu and all it changed was made the "hunting idle" faster, Im hoping I didnt f up the IACV cleaning it. Also how can you bleed the air out your coolant if the bleeder screw is gone? My coolant was low and I filled it earlier

 

According to this writeup if the car sputters and dies when you cover up the top hole in the tb the IACV is to blame, is that right?

 

I would look for vaccum leaks by getting some brake clean or something and spray it all around the iacv and if the rpms change at all you know there is a leak cause the brake clean made its way into combustion chamber and is trying to combust. just a thought.

 

yeah I picked up some starting fluid today to try that

 

It sounds like you need to bleed the coolant system.

Put the heater to hot but leave the fan off.

Remove the radiator cap. Start engine. Top off fluid level as needed. Wait until the cooling fan kicks on once. Turn engine off and re-install radiator cap.

 

I topped it off and let it get warm with the cap open, still doing it

 

Ok update, I bled the coolant again today, and popped the intake off and covereed the holes, when I block about 3/4 of the flow to the IACV it idles perfect?

 

Ive got a spare IACV. Do you want it?

 

check gaskets around manifold and tb and make sure there is no vaccum leaks

 

Ummmmmmmmmmm starting fluid loved by deisel owners and number one way to find piston rings in your oil on a gas motor.

Well that small of a mist isnt going to hurt anything and it seemed like a btter idea then the previous suggestion of brake cleaner...

 

Hey yoffer how much for that iacv?

 

Ok I pulled the valve off again, and made sure it sealed this time. The car idles better and runs PERFECT with the a/c on now, But still hunts for idle with the a/c off. Im gonna try replacing the valve
