IAC valve replacement help

[97camRS]

When replacing the Idle Air Control Valve is there any adjusting that needs to be done before putting the new one in? I was about to put my new one on and figured I'd ask first.

Nope, just plug-n-play ;)

I went to change this thing this morning and I can't figure out how to get the 2 screws/bolts out. They look like Hex screws but are rounded out. I tried every size socket I could think of and none worked either. Can someone confirm if what I need to get these things out? Thanks

If allens don't work it's probably a torx. I'd have to see it to be sure.

I haven't had another chance to take a look at this. Does anyone know what's needed to get this off?

I know the MAP sensor uses a Torx head and I'm pretty sure the IAC is the same, although I don't know for sure offhand.
