• Q: How to replace the throttle body assembly on 2005 Cadillac DeVille?

  A: Begin replace the Throttle Body by draining the fuel system pressure first. First disconnect the cruise control cable connected to the accelerator controls cable bracket followed by the removal of air cleaner intake duct alongside the pcv valve fresh air tube and accelerator controls cable bracket. Climb up to disconnect the accelerator cable both from the accelerator controls cable bracket and the Throttle Body lever. Remove the electrical connections connecting the iac valve to its electrical harness and connect the tp sensor to its electrical harness. Extract the fuel feed and return lines from their retainer position on the accelerator controls cable bracket followed by removing the transaxle shift cable clip from that bracket. Start by taking the Throttle Body away from the water crossover and the accelerator controls cable bracket from the Throttle Body. Installation requires the use of a carburetor cleaning solution which excludes methyl ethyl ketone. Carburetor cleaner should be used for cleaning deposits. You need to make sure the air cleaner outlet matches the maf sensor duct perfectly to prevent airflow problems. Secure the new Throttle Body Gasket onto the Throttle Body before installing the accelerator cable bracket while tightening its bolts to 12 n.m (106 lb in). After placing the Throttle Body onto the Throttle Body spacer apply finger pressure to the lower bolts followed by a full bolt torque of 12 n.m (106 lb in). Connect iac valve and tp sensor electrical wires and install the accelerator control cable and cruise control cable at the Throttle Body lever. First attach the accelerator cable to the accelerator controls cable bracket then install the transaxle shift cable clip followed by reconnecting both the fuel feed and return lines. After installing the clamp for the air cleaner's intake duct tighten it to 3 n.m (27 lb in) while also putting in the pcv valve fresh air tube and fuel injector sight shield. To complete the installation follow these last steps: first attach the negative Battery Cable before starting the tp sensor learn process with a one-minute ignition run/on state then a fifteen second lock/off position. After engine startup the iac valve learn procedure includes a 15-second engine idle followed by 15 seconds in the lock/off position before restarting the engine to confirm proper idle operation.
