• Q: How to service and repair the Throttle Body on 2000 Chevrolet Malibu?

  A: The Throttle Body repair process begins by turning off ignition then draining engine coolant. Remove first the iat sensor connector then the breather tube from the air intake tube and finally detach the air intake tube. Before starting service disconnect the electrical components of the idle air control valve and Throttle Position Sensor and remove the accelerator controls cable. Before moving forward disconnect the cruise control cable from the throttle lever and accelerator bracket and then uninstall the accelerator control cable bracket. After disconnecting Throttle Body coolant bypass hoses you must remove the heater pipe nut that secures the Throttle Body. First you need to remove the nuts which secure the Throttle Body to the Intake Manifold before taking out the entire Throttle Body assembly. Before assembly install the Throttle Body to Intake Manifold put all gasket contact surfaces through a cleaning process using no solvent that could harm the exposed areas. Put on a new gasket when needed afterward you can reposition the Throttle Body assembly. Use retaining nuts and bolts to secure the assembly before torqueing it to 28 n.m (21 lb ft). Reinstall the Throttle Body coolant bypass hoses along with heater pipe connections and both electrical components of iac valve and tp sensor. Reinstall the accelerator controls cable bracket before you reconnect the cruise cable (if present) and connect the accelerator controls cable. Fasten the iat sensor electrical connector back into the air intake tube before securing the breather tube to its proper position on the air intake tube. You should complete the procedure by adding engine coolant before checking to verify the throttle moves smoothly throughout its full range of motion. Throttle opening and closing functionality should be checked through accelerator pedal testing to verify proper operation while inspecting carpet installation beneath the pedal.
