I will check this tonight or tomorrow and let you know.

quote snshddog: Those tps sensors were netorious for never being good, along with other aspects of those carbs. Most people change out to an older carb without the computer control. The variance might be from rust inside the wire changing the resistance which changes the value on a meter.
I would like to keep the current electric one so that I can connect my laptop to the computer for diagnostic purposes. I believe that rust in the wire or on the contacts/connectors could very well change the original resistance of the wire, but I don't think it would be variable nor would it cause the reading (voltage) to slowly decrease.
