Title says it all.

Cleaned IACV, FITV, and even before this I believe the idle control screw is not functioning.

Just trying to adjust idle so it runs smoother when fully warm. Currently idling around ~600RPM.

 

Define non-functional.
Did you jumper the service connector when you adjusted the idle?

 

When I turn the idle control screw, the idle does not change.

I did not jumper the service connector, no.

 

The FAQs sticky has an idle adjust diagram for your car/engine. Follow the procedure exactly.

 

So.....while playing around with this...I was still not noticing idle change...unplugging the IACV (which threw a code) and adjusting the idle screw, shutting off car, plugging plug back in...resetting ECU by pulling back up fuse...and restarting vehicle..

So I pulled off the air intake...blocked the hole inside the throttle body..and nothing happens.

Bad IACV?

No CEL and yes, it works.

 

wouldnt the engine stall if you blocked the hole at idle?

 

Nothing happened at all when blocking the hole at idle.

 

Bump?
