Any one else ever have issues with their idle air control valve or have to change them? Since I bought the car 3 months ago, it tends to stall after pushing the clutch in coming to a stop. Once car is warm it pretty much stops but when cold I've had it stall on me several times. I can try to take a video of it if that helps.

I took it off and cleaned it thinking it was dirty and it was. Seemed to work better for a while but now doing the same thing if not worse. Should it be time to change the valve all together or could it be another issue?

 

A bad iacv will never cause your car to stall. It will normally cause your car to idle higher when it goes bad. A bad oxygen sensor or an exhaust leak would be where i would start looking.

 

But why would the symptoms stop once the car completely warms up? Maybe just coincidence

 

If it happens when the car warms up it's likely one of the closed loop sensors thats bad, likely the oxygen sensor, possibly due to an exhaust leak or its just old and lazy.

 

Could that be why it's throwing the knock sensor code p0325? Not getting enough air due to bad oxygen sensor? Or maybe just sensing to little
