How to service and repair the throttle body on Mercury Grand Marquis?

The first step for servicing the throttle body requires maintaining safety protocols which include staying away from using open flames and smoking near fuel-related parts because highly flammable mixtures exist. Start by separating the air cleaner outlet tube followed by disconnecting wires connecting the throttle position sensor and accelerating and speed control cables. The throttle return spring should also be detached. You must first discard the throttle body gasket before securing the throttle body with four bolts. To install the parts you should use a new TB gasket then install the throttle body while tightening its bolts in two stages using 9 Nm torque (80 lb-in) followed by rotating the bolts by 90 degrees. After reinstalling the air cleaner outlet tube you must finish restoring all connections between throttle return spring as well as accelerator control and speed control cables and throttle position sensor electrical connectors.

The Throttle Body of Mercury Grand Marquis vehicles regulates the amount of air going into the engine; it has a butterfly valve that opens as per accelerator pedal position. While older models applied Throttle Body Injection (TBI), the modern models apply multi-port fuel injection. Electronic Throttle Control (ETC) is now standard as it does away with mechanical linkage making the car safer and to perform better. Throttle bodies can be cleaned and replaced and auxiliary components such as TPS sensors and IAC valves can at least be replaced. Throttle bodies are essential for managing air intake and further also the fuel supply to fuel injected engines which in turn affects the performance of the engine.
