Best test is to mark position, remove, and inspect the pot contact area. This will reveal badly worn contact areas.
Throttle switch is just that - should measure infinity open, and zero Ohms closed.

Hi Steve, I have read your write-up re R&R of the pot. A project for the future for me since this car is my daily driver.
What I am trying to do is to set the air/fuel ratio mix properly. The values set for percentages at idle, deflection of throttle plate, and open throttle are given standard, before any adjustments are to be performed. http:\
