Have you tried removing the TPS off the throttlebody itself? If no...then I aint gonna offer suggestions anymore. If you dont remove the TPS from the T-body then how is the schidt you are cleaning off the return spring gonna get out from behind there? And how are you sure that the spring aint kinked or binding. Take the frickin TPS off the side and clean the spring area proper.
