• Q: How to replace the throttle body assembly on 2004 Cadillac DeVille?

  A: Beginning replacement of the Throttle Body assembly demands you first reduce fuel system pressure. The process begins with removing the air cleaner intake duct, the pcv valve fresh air tube along with the cruise control cable from the accelerator controls cable bracket. Then detach the accelerator cable from this same bracket. Disconnect the Throttle Body lever's accelerator control cable and cruise control cable followed by separating the iac valve electrical connector from the iac valve and the tp sensor electrical connector from the tp sensor . Cut off the retainer holding the accelerator controls cable bracket's fuel feed and return lines then remove the clip that secures the transaxle shift cable to the bracket and pull out the Throttle Body that sits above the water crossover. Remove the accelerator controls cable bracket from its position on the Throttle Body. During installation avoid using methyl ethyl ketone because it can damage materials. A carburetor cleaner should be used instead of a methyl ethyl ketone cleaning agent to remove deposits. Make sure the air cleaner outlet and maf sensor duct properly match for optimal airflow operation. Put a new Throttle Body Gasket onto the Throttle Body before mounting the accelerator cable bracket to the Throttle Body while tightening bolts to 12 n.m (106 lb in). Start by connecting Throttle Body bolts to the Throttle Body spacer then finger-tighten the bottom pair before torquing all bolts to 12 n.m (106 lb in). Continue the electrical connection between the iac valve and its connector and between the tp sensor and its connector. Screw in the accelerator control cable through the Throttle Body lever as well as the cruise control cable to the identical lever. Link both the accelerator cable to accelerator controls cable bracket as well as the cruise control cable to this bracket. Reinstall the transaxle shift cable bracket clip together with the fuel feed and return lines from their retaining brackets onto the accelerator controls cable bracket. First secure the air cleaner intake duct clamp to the air cleaner intake air duct before tightening both clamps to 3 n.m (27 lb in). After that properly install the pcv valve fresh air tube and the fuel injector sight shield. Begin by connecting the negative Battery Cable before running the tp sensor learn procedure with a one-minute run/on switch position followed by a 15-second lock/off position. First complete the iac valve learn procedure through a sequence of engine start, 15-second idle period, ignition switch move to lock/off for 15 seconds and a final engine restart to verify proper idle.
