• Q: How to replace the throttle body assembly on 2000 GMC Jimmy?

  A: To remove the Throttle Body assembly, you first need to remove the air cleaner outlet duct and the air cleaner adapter stud. Pull the cruise control cable and the accelerator cable off the Throttle Body and take the nuts off the accelerator cable routing bracket and put it aside. Then, unbolt and take away the stud and nuts holding the accelerator control cable bracket and store it with the rest. Remove the iac valve harness connector and the tp sensor harness connector and remove the Throttle Body retainers and remove the Throttle Body assembly, discarding the Throttle Body seal. Clean the surface of the seal on the Intake Manifold and attach the Throttle Body assembly with a new seal, making sure you tighten the studs on the Throttle Body to 9 n.m (80 lb in). Reinstall the accelerator control cable bracket using the mounting stud and nuts and tighten to 12 n.m (106 lb in) and then the accelerator cable routing bracket nuts at 9 n.m (80 lb in). Check for throttle restriction freedom by means of operating the accelerator pedal, and making sure nothing is binding. Mount the accelerator cable and cruise control cable onto the Throttle Body and hook the tp sensor and iac valve harness connectors up. Install the air cleaner adapter stud with tightening it to 8 n.m (71 lb in), and then install the outlet duct of air cleaner. Lastly, test the accelerator pedal operation by turning on the ignition while the engine is off using a scan tool by testing the tp sensor parameter and ensure the throttle position changes from 0-100 % and to 0% in reverse.
