-If- the issue is with the TPS (or other electronics) in the Throttle Body - then Yes, replacing w/ the extra working oem throttle body should fix the issue.thank you for your response.
yes it uses an electric tb. Before getting the volt meter out, etc I happen to have an extra working oem throttle body I have not used before. if it's indeed a TPS issue, replacing the throttle body with a known good throttle body should fix the issue, right?
As a "parts swap" test: it won't cost you anything, and will either confirm / or deny the (electronic throttle body) is the issue. Recommend making sure you have any TB -> to manifold / plenum gaskets needed, prior to doing the TB swap.
