I ran my 03 America with the TPS disconnected for years. It eliminated the decel popping completely. Originally mine was acting up causing misfiring and stalling. My TPS resistance values were all over the map. I simply unplugged it leaving the old TPS bolted to the carb. Don't leave it plugged in if you plan on only unbolting the TPS from the carbs. The ECM will see only that one throttle signal and get confused. Apparently electrically disconnecting the TPS changes the timing (not confirmed) to a default setting which seemed to work for many of us. I think I put close to 40K kilometers on it disconnected with nary a problem.
Oh, from what I remember, I'm pretty sure I messed up my TPS with a pressure washer and was actually glad I got to disconnect it because I hated the decel popping and this got rid of it immediately.
