It sounds like you are talking about the IAC (Idle Air Control) not the TPS (Throttle Position Sensor). The IAC is usually very stiff to move by hand but has to be adjusted to a certain length before installing. Sorry I dont remember the exact length. Somebody else here can probably advise you on that.

Good Luck
