I had pretty bad throttle hang and it went away when I replaced the TPS.

But in that case it had gotten worse than what would be considered normal for that car.

So if the throttle hang suddenly gets really bad it could be the TPS, but don't expect a TPS replacement to fix the normal throttle hang.
