Not yet, I was afraid I'd snap something off and be totally screwed. I'll give another go in a bit.
​​​​​​​I love nutter butters, and a sleeve is just a tease.

Pull the top of the manifold off and flip the entire thing upside down to access the IAC. More work but the throttle body studs won't be hacked up.

I believe it is an AC Delco part. Is there a # printed on it ? I have a 95 502MPI tbody (and many other things) in my garage but too lazy know to go downstairs and check for you.

AC Delco parts on Amazon are cheap and usually in stock. AcDelco partnered with Amazon a few yrs ago.

As always, do your homework to make sure this is what you are looking for. It's your boat, not mine.

This is $20 more, but comes with the Merc throttle body gasket you probably have to replace. Free shipping also .
And yeh, both are a Merc part #.

Where did I hear that this was actually more like a Ford Windstar IAC?
