Default Cleaning TPS (Throttle Position Sensor)?

Hi all:

After 208K miles I think my TPS has finally gone south. I'm getting unusual and annoying shifting action so tested it per the FSM and it fails - sort of. Looks to be intermittent. I cleaned out the throttle body and adjusted per FSM but am still getting intermittent shifting issues. Curiously, I don't have any pending OBD codes indicating flaky TPS signals. P0120 I think.

I can find nothing from the search function on this but before I spend $170 on a new one has anyone had experience cutting one open and cleaning the contacts? On some other forums people talk about drilling small holes and squirting contact cleaner to buy some more time. Anyone tried this?

Thanks in advance.
