Rough Idle with 3 codes, Anyone had this problem
P123 - Throttle position input High Circuit A
P222 - Throttle Position Input Low Circuit B
P111 - Intake air temp range
I have the Generator light, ESP, and Check engine dummy lights lit. It idles rough as hell and drives just as bad. The throttle appears to be working as it revs and in general acts like a old Carborated car when you first crank it up.
I have checked for vacuum leaks and cant find any although the intake manifold vacuum sounds LOUD. I pulled the PCV hose off (intake side) and it is pulling like crazy but then again never did it when it was normal so i have no comparison to judge.
Wondering if any of you guru's have had this happen or what might be the cause and or a fix.
It will drive but will eventually "Die" like its a battery or alternator failure which is what i thought it was but both test sat.

Could it be the PCV valve?? or the Throttle body? I saw other threads with similar results but not same codes.
