• Q: How to replace the throttle body assembly on 2005 Chevrolet Astro?

  A: The first step to replace the Throttle Body assembly requires the negative Battery Cable disconnection followed by removing the engine cover and air cleaner outlet resonator and its adapter stud. Duplicate the accelerator cables before you loosen the mounting stud and bracket nuts that hold the brake control bracket. Store the bracket for later use. Begin by disconnecting the iac valve harness connector and tp sensor harness connector before removing the Throttle Body retaining studs that lead to complete Throttle Body assembly removal. Toss out the Throttle Body seal during this process. During installation clean the Intake Manifold gasket surface and apply the new seal to the Throttle Body assembly before securing the assembly with retaining studs at 9 n.m (80 lb in). After tightening the resonator adapter stud at 8 n.m (71 lb in), reconnect the iac valve harness connector and tp sensor harness connector. Reinstall the accelerator control cable bracket by using fasteners that require 12 n.m (106 lb in) torque setting. The accelerator and cruise control cables should not stay opened when ready. Replace the air cleaner outlet resonator and engine cover before reconnecting your vehicle's negative Battery Cable. Check acceleration control by deploying the accelerator pedal until it reaches the floor to verify effortless motion without restriction at both throttle positions.
