My 99 Gs 400 just threw a P0121 code, the VSC off light stays on and the throttle doesn't respond when i push it down to accelerate. From my knowledge its the throttle position sensor. Where can I find a good price for this sensor? and are there any write up's on how to replace this part?

need some help

Thanks in advance.
