Q: How to service the throttle body on those equipped with speed control on Mercury Cougar?
A: The service of the throttle body starts by taking off the air cleaner outlet tube and intake air resonator in speed control-equipped vehicles. Start by disconnecting the speed control cable from the throttle body before detaching it from its bracket through cable-out by pushing the retaining clip. Pull the accelerator cable retaining clip after which you can disconnect the accelerator cable from both the bracket and the throttle body. As part of the vacuum hose removal you must also disconnect the throttle position sensor electrical connection. You should remove the throttle body assembly together with the throttle body gasket for disposal. The installation process requires a new throttle body gasket while performing the reverse procedure but it is essential to avoid cleaning the throttle body because the bore and throttle plate have a special coating that should not be removed.
Q: How to Properly Handle and Maintain the Throttle Body on a Mercury Mariner?
A: Start the process of servicing and repairing the throttle body by disconnecting the lead of the battery ground cable. The service process begins by removing the air cleaner outlet pipe after which technicians should detach the upper snow shield screw along with its pin-type retainer before taking off the upper snow shield while tightening all bolts to 10 Nm (89 lb-in) after installation. Start by disconnecting the speed control cables together with the accelerator cables from the throttle body followed by removing the throttle position sensor electric connector. The four bolts holding the throttle body must come off before examining the gasket's condition to determine a replacement decision. Follow the original installation steps by tightening the throttle body bolts to 10 Nm (89 lb-in) before finishing the procedure.
Q: How to service and repair the throttle body on Mercury Grand Marquis?
A: Safety measures should be implemented first before working on the throttle body since flammable mixtures exist inside it. Start the service by disconnecting the TP sensor electrical connector and removing the air cleaner outlet tube followed by the throttle return spring then the accelerator followed by the speed control cables. The service starts with dismantling the throttle body by stripping its four securing bolts and disposing of the Throttle Body (TB) gasket. Set a new TB gasket in place before reattaching the throttle body using bolts which should be tightened twice: initial step to 9 Nm (80 lb-in) followed by 90-degree rotation of the bolts. Reinstall the air cleaner outlet tube only after reconnecting all components starting from the throttle return spring and accelerator cables and speed control cables then moving to the TP sensor electrical connectors.
