I just cleaned a spare IACV from an old throttle body of mine couple minutes ago using this technique and now she spins like a top. I'm stealing the sensors off for a new TB. Only thing I'd like to add to this is if you're going to use a Dremel and slot out the screws holding on the IACV, you might as well slot out the tamper-proof screws on the TPS couple inches away.
