FIXED = IAC :) Turn key, no start unless giving mucho gas.

Hey guys,
Always come here first as the advice Ive received has always fixed the problem in the past.

Stock 99 Explorer...

Problem is just as title states. Out of no where, Explorer will not start unless stomping on the gas, and will not hold an idle to save its life.

I've cleaned the IAC, and the throttle body... Didnt work THIS time.
I guess next is the MAF?
Should I check the throttle position sensor? If so, where is it located and how do I do it?
Hopefully I can get it fixed fairly quickly, or its going to the dealer.
I dont have a code reader or any other fancy tools.
Thank you in advance everyone, it's such a crappy feeling when the Explorer starts acting stupid.
Matt

It might be time for a new IAC. Cleaning only works up to a certain extent.

Holding the throttle wide open while cranking SHOULD be shutting the injectors off to clear a flood condition...or at least forcing much more air and making it very lean. Do you have some bad injectors that are open or leaking?

Thanks for the response guys.

New IAC did the trick.
