Well of all the places I've called the only gaskets anybody has in stock are the TB to intake gaskets, can I take the throttle body off and only replace this one and be fine?

UHHHHHHHHHHH...if you're only removing the throttle body, that's the only gasket you need to replace.

Depends on the condition of the gaskets. I've had my TB's off and back on without replacing the gasket several times.

If you're talking about taking the IAC housing and the TB plate on top off of the TB itself, then you'll may end up needing to replace those. The IAC housing moreso than the TB plate.

Thanks, thats what I was thinking. I guess I'll just try to clean it out as much as I can without taking it off.

the iac uses an o-ring, if you are careful you can reuse it. as long it isn't hard or broken you shouldn't have any troubles.

I wasn't talking about the IAC O-Ring. That thing is a pain, and you can't find it anywhere. If it crumbles (which it probably will) just go to the auto store and buy a roll of gasket material and cut a new one.

I was talking about the IAC housing on the bottom of the TB.
