Ya possibly that or your tv cable came un done...I know my buddy replaced his tps on his2e000 gt and auto zone gave him one for a v6...next day it was downshifting all crazy...acting up...so yours could be going bad
Thanks for the offer Jeff! Unfortunately, I am in Germany. I went ahead and ordered a new one. I should have changed mine like you did. I swapped out my junk plastic manifold for the professional products manijold and t/b. Made quite a difference!
