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.

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.
