this is gonna sound really dumb, and hate to ask......
was the TPS installed right? On mine there is a spring lever thing which controls the throttle plate in the intake(throttle body), if its not on right, which I did when i first replaced it. and then took the battery cable off for ten minutes, the idle still went high and still had code coming back.
when I looked at it and re-installed it and yeah disconn batt for ten minutes....the problem went away and she runs fine now.
just my two cents sir!
