• Q: How to replace the throttle body assembly on 2004 Chevrolet Silverado 1500?

  A: Begin Throttle Body assembly replacement by taking out the air cleaner outlet resonator component with its securing stud and disconnecting the cruise control cable from the throttle pulley and the engine bracket. Begin by taking off the accelerator control cable first from the accelerator control bracket then from the engine bracket. Then remove the accelerator control cable slug from the throttle pulley. First detach the Throttle Body accelerator control cable bracket nuts before removing the bracket and cables attached to the Throttle Body assembly. Afterward properly secure the cables and bracket out of the way. By disconnecting the throttle position (TP) sensor electrical connector and idle air control (IAC) valve electrical connector you can start removing the Throttle Body studs along with the Throttle Body itself while discarding the Throttle Body seal. Begin by installing a new Throttle Body seal followed by the Throttle Body then install and tighten the Throttle Body studs to 9 n.m (80 lb in). Unplug the tp sensor and iac valve electrical connectors before installing the accelerator control cable bracket with the Throttle Body connected cables. Tighten bracket nuts to 10 n.m (89 lb in). Secure the accelerator control cable slug at the throttle pulley before connecting both cables to install at the engine bracket and accelerator control bracket. Featuring in the installation sequence is the cruise control cable assembly between engine bracket and throttle pulley. The process continues with air cleaner outlet resonator stud installation before final tightening to 10 n.m (89 lb in). Last, the air cleaner outlet resonator goes into place.
