Hi, HT. I'm recently experiencing low idling at every stops, sometimes it gets to low that the car just stalled. What's wrong? HELP.

 

Check your IACV

 

Is this common problem with iacv.

 

If you are idling weird at start up as well then it should be your IACV. Do you have to add gas just to keep your car alive?

 

The car starts up normal, but once it warms up, that's when the rpm go low. Yes, I have to give it a little gas to keep the car alive. It helps a bit when I adjust the screw in the throttle body.

 

A bit of history would help.

Did this just start all of a sudden?
Did some sort of work precede the problem?
Has the idle been CORRECTLY set (and I don't mean just monkeying with the screw on the throttle body)
Is the Check Engine light on?

 

This just happen after I ran hard. I didn't notice anything differently until I got off the freeway. No check engine light.
