TPS sensor gone whacky?

[FromaBuick6]

I recently had my TPS go hay-wire and read 2.5 volts at idle and all the way through the throttle range, so I ordered a new one from Postons. After running it for a few days I noticed some bad drivability and a CE light. Direct Scan showed that my TPS was reading .42 volts at idle, but after a 10 minute drive, it's now .25 at idle. Drove back home and it's .42 again. It set a TPS low voltage code as well. Do you guys think I got a bad TPS from Postons, or has something else gone crazy? - FAB6

Odds are intermittant wiring and connections rather than 2 bad TPS sensors.
