Intake Air Control Valve

[RR|Suki]

Well my cars revs have fallen quickly if you rev ever since I got it. Didn't think anything of it, my bike's current tune does the same thing. However it finally happened, it got stuck on me and stalled at a light at the end of a freeway off ramp. started it back up and it's been fine again for days, I know it'll happen again, so I'm just gonna replace it. What the heck is the right part number for it? should I just contact ray...:confused:

P.S. I kinda miss my dual Webber carbs right now, lol

Mine does the same thing. I cleaned mine out with some carb clean and it worked for a day but now it's back to usual. I'm going to contact a member here called "TheDealer" (that correct, everyone?) and he'll be able to get us (hopefully) the IACV for us. The Ford dealer by me wanted $100 for it.

It is in the tuning, do not blame the IAC Valve.
In the SCT Software, you adjust the isc_Drive_Idle_Air values and it remedies this condition.

Zack, can you further expound upon this thought of yours? Is the SCT in regards to the Trilogy Supercharger Tuning?

I can see the tune causing the sharp revs, like I said my bike does it too, no biggie. My thing is the random stall at idle... I'm gonna get retuned by Lidio sometime soon here hopefully, you recomend just waiting till then Zack?

The engine dies when the throttle blades close suddenly.
The function of the SCT software commands the IAC Valve to open more, compensating for the closed throttle blades, thus allowing the car to stay running.
