  Q: How to service the throttle body safely and effectively on Chevrolet Tracker?

  A:

  Beginning Throttle Body service requires eye protection for the safety of your eyes from compressed air usage. Start the service with Throttle Body removal from the vehicle while the idle air control (IAC) valve and throttle position (TP) sensor must be disconnected because compressed air and solvents could damage these components. Wipe down the throttle valve and throttle bore until all accumulated dirt and carbon deposits are removed. Clean all dirt and carbon debris both from bypass air passages and the crankcase breather passage along with its pipe. Use compressed air to perform a complete cleaning of these system components. The install of the Throttle Body requires a throttle valve inspection to ensure free movement before the final attachment.
