[s-cars] Throttle position code help

I have a problem with my Throttle position sensor.

00518 - Throttle Position Sensor - 27-10 - Implausible Signal - Intermittent.

It is intermittent happens once or twice a day at the most but when it
happens the car feels like it hit a brick wall (goes into a fuel cutoff mode
for about 0.5 seconds).

I want to drill a hole in the position sensor and spray contact cleaner into
it and then replug it with a rubber plug.

Any suggestions where I should or should not drill?

Best regards,
