where do i remove a 2000 Chevrolet Express 1500 Throttle Position Sensor

Hello jerryd333-- Follow the gas pedal cable until you come to the place it connects to the throttle body. The TPS (Throttle position sensor) is generally on the opposite side to where the cable connects. It is held on by a couple of clips which are easily removed. For future reference I always remind people that they should quiz the man at the parts counter when you buy your new part. These are often the most knowledgable guys in the business and they can have you out there getting yourself all greasy in no time flat. Good luck from Bovan.
