I had a Production run 4778637AB IAC
From china

If anyone is interested in purchasing a new IAC 4778637AB which is for a GenII

I’m not a vendor. I’m a member in good standing

If member interested in purchasing one of these from me let me know
I’m looking to sell only to members at my cost plus shipping
I’m not into it to make a profit just to help others that can’t find a IAC that works if replacing

I had tried a few IAC from different companies and knowing that some of those suppliers are selling versions that are for Gen III or Gen IV. And really don’t work well in random idle wondering when warm. And these suppliers are charging in the hundreds

My costs are under 10 dollars plus shipping

Let me know if any members in good standing want to buy one from me
I am not selling to anyone who is a vendor or reseller. Members only

Brian

It’s the idle control valve
Which is on passenger side near the front of the engine that controls the engine idle

The part is no longer manufactured

All that is available for the IAC is for a 2004 to 2006

I think that’s a GenIII

I have not have had much success with a gen III version

Note: the below occurred with using an aftermarket IAC from a big box retailer:

I have an idle run on after the car is warm and sometimes idles around 1500rpm with products that are only available in the open market

The only part that is available is 05245352AC from NAPA and their name brand for over $120 dollars

Just a point of reference.

Please check the internet for pn 05245352AC
It’s for another Gen other than Gen II

All, I just met up in person with Brian and purchased a couple of these from him. It's all legitimate and he's an honest guy. You can't beat $10 plus shipping

The data in this thread is all over the place, so let's clarify.

You are selling Gen 2 idle air control (IAC) valves, part number 4778637AB.

The Gen 3 idle air control valve is still available (part number 05245352AC), but will not work in a Gen 2, hence why you had the Gen 2 IAC valves reproduced.

The Gen 4 (and 5) do not have IAC valves, so any references to those in this thread should be ignored. Idle air control for those engines is handled by the throttle body blades since they are drive-by-wire (i.e. they don't use a physical cable attached to the gas pedal).

Feel free to correct (minus the Gen 4/5 part, because I know that to be true), but that's how I read the info. Just wanted to make sure everyone is on the same page here.

Made an error. I meant 10 units at 9 dollars each for a subtotal of $ 90 dollars + shipping + transfer service fee if using PayPal Venmo or Zelle
