Got these 2 codes right now.

-Intake air temp ckt signal high
-IAT ckt intermittent high voltage

What the heck does that mean?

i could be wrong... but that may have to do with your tps sensor... however, if it was a complete tps failure it would be p0121... so im not exactly sure.

have you done anything new recently to maybe trigger this?

 

according to the flow chart, if all your wiring is good, you need a mass air flow sensor, b/c the iat sensor is inside the maf!!!

Yep, IAT sensor is in the MAF...more than likely she is kaput...
