I would imagine so because I can't think of any other reason why the ECU would want to know the temperature of the outside air. It would have to know this to match the A/F ratio to either cold, dense air or hot, not-as-dense air.
Wheeler said it sounded like a sensor went bad. It would make sense that if that sensor went bad the ECU would default to dumping in more fuel as a limp-home mode instead of leaning it out to the point where it might not even run....
Do you realize that if this is the problem you've spent how much time/effort/$$$ in extra gas for a $16 part? I'd almost have that damn thing overnighted.
