I need a idle air control valve and none in stock. Need today, does anyone know if I could get it at auto parts? Thanks John

BY U BOY

Should Be Able To Get It At Your Chevy Dealer.

The two wire Pulse Width Modulated IAC used on the 496HO is actually a Ford part. I don't know the Ford part #.

When I replaced mine, I went to the Chevy dealer, and they couldn't match up a Chevy IAC. They said everything they had, mounted to the throttle body, and they had nothing that mounted to the manifold.

Makes sense now.

Thanks guys, once again the knowledge of oso amazes me. Even on a 90 degree sat, at least here. Guess I'll have to wait.

fountain27ho496, did you find a place to buy this besides Merc? I need one now and they are still out of stock. Say it will be July 17th or later. Or does anyone know? Also is the IAC on a 496 the same as a 496HO? I would think they would be.

Find a friend that knows someone the at Ford dealer. Many common components, are on many different brands. Sometimes the part has been improved upon, or superceded to reduce overall inventory. You could get out an Ohm meter and match resistance or even better find out all the info and match the part with another by finding out it's data. BBB

The answer may come a little late, but it might help future needs though.
I happend to run into some nice pic's on the net while searching for a 496 IAC valve and I agree they look very similar as, but not exactly like, IAC's used on Ford engines.

So I found that the 496 IAC seems to be Hitachi made, sold under at least the Edelbrock brand as part # 36017, probably because it seems like the pcm-555 ecm is actually a MotoTron product.

Just my 2 c thoughts ...
