In order to replace the Throttle Body assembly, you should disconnect the negative Battery Cable and remove the engine cover, air cleaner outlet resonator, and air cleaner outlet adapter stud and detach the cruise control and accelerator cables. Then, take out the nut and stud that secure accelerator control cable bracket and put it to one side after that disconnecting idle air control (IAC) valve harness connector and throttle position (TP) sensor harness connector. Take out the Throttle Body assembly by removing Throttle Body retaining studs and throw out the Throttle Body seal. For the installation process, the surface of the gasket on the Intake Manifold needs to be cleaned and then the Throttle Body assembly installed along with a new seal while tightened with the retaining studs at 9 n.m (80 lb in).

Move on to install the accelerator and cruise control cables, then air cleaner outlet resonator and engine cover, and finally reconnect the negative cable to battery. Ensure the accelerator pedal moves freely with no binding between full and closed throttle by pushing it down to the floor and then releasing it.
