Helped on gas mileage
I had manually cleaned this part a couple times - once out of necessity as my Jeep Liberty wouldn't stay idling - as well as for the fact that I couldn't find this part for less than $60 elsewhere. Once I found it for around $18 at 1A Auto I figured I couldn't lose. It's been running smoother and I've noticed my gas mileage tick up almost 3 mpg already. Very pleased.

Bad Idle Valve
The idle valve is no good. It won't throttle down
Idles around 1600 rpm.
Had to put the old valve back on.
Could be one in a million bad? Coded idle valve no good.
Also the plug in was hard to mate.
