    I just changed my email to 'visible', so however you want. But post it up; if I'm wrong, won't be the first time (or last).
    I'm hopin' to see this too here...

    Message to Schrade. Why does it say "Banned" Under your name? Look on page 6E3-B-13. IAC operation. This controls vacuum. A vacuum leak doesn't always cause a loping issue. Try not to be so antagonistic.

    I was lookin' at that very page last night - 'Incorrect idle' (the first 2; rough, or unstable, sure ain't gonna' be 'steady high' idle). And then the 'definition' below that is "Engine runs unevenly at idle..."

    I don't see how IAC could account for a high steady idle. It says if it's unplugged and reconnected while running, it might be wrong. It says re-set (re-calibration) takes 5 seconds to figure that out, or it will re-learn the proper calibration in a few drive cycles. That's a GOOD IAC. If the pintle spring is broken, I don't think it's gonna' be a steady idle - low, OR high... HibH said it could cause 'unstable' idle. I don't think ANY vacuum leak will make a steady idle.

    If I'm wrong, I wanna' know it. With proof. A dull knife isn't a knife - it's a saw. And saws make a mess. Knives cut clean, and gettin' 'em sharp is gonna' generate some heat... It says BANNED from CF for tryin' to cut through the 'stuff', and sharpen the blade in the process.

    Pull a vacuum hose off and see what happens.... high steady idle. Isn't that a vacuum leak ? It seems to me the IAC is a controlled leak.

    No. Not steady. Loping only.

    Exactly correct...IAC = electronic controlled "vacuum leak" (by the PCM/ECM)
    Another "vacuum leak" the throttle blades themselves controlled by....the drivers foot.
