That's the drag with those warranties; yeah, they'll give you a new one, but.. I had problems with MFS's around '05, I ended up buying 2, and just keeping a new one in the car. (No brake lights sux!) I finally disassembled my original one, cleaned and refilled it with dielectric grease, and it's working almost 20 years later. Needless to say, when the other cars had problems, I'd yank it and fix it on my lunch break. One of the older Scientists, a Belgian guy, was fascinated, watching me take it apart, sand the copper parts, coat them with grease, and put it back together. I think I still have 2 of the az ones in my garage, lol.
I ran across this iac cleaning thread, and something Jumped out at me:

What!!!!! You didn't take off the plastic cap
The outside black plastic cap that easily spins will pop off and snap back on without damage. Inside there is a felt filter pellet. Cleaning just the valve without removing this often cloggs this filter up worse. This source of back air flow balances the valve and provides clean air to prevent buildup on valve. Often just cleaning this will get rd of the moose calls. Add pictures of this and you have something.
We had a thread on the moose call problem, and I've never seen this. I have an old one in the garage, And the one in Lazarus was doing it last time I started it.
This makes a lot of sense to me, and I'd bet this sensor is a pressure regulator, and when it gets dirty it oscillates, and the moose call results. That explain why popping the throttle will stop it sometimes, it moves the clog around.

How to: - IAC valve cleaning thread (w/pics)
Have you ever noticed a loud hum and/or whine (whining) coming from your engine bay? Or more specifically your intake area? Or does your engine have a hard time holding the idle? Well, more often than not, this is due to a dirty IAC Valve. Since everyone is always asking about it, hopefully...
