How to Replace Throttle Body?
Remove air cleaner and duct hose with a screwdriver. Disconnect electrical connector on the MAF by pulling out the plug. Disconnect intake air temperature sensor in the air duct.
Disconnect idle air control on the side of the throttle body by pulling the electrical connector. Disconnect the throttle position sensor opposite the throttle cable levers.
Disconnect throttle cables by turning the throttle lever on the throttle body all the way open by hand and removing the now slackened cables from the throttle lever.
Remove bolts running through the throttle body and into the intake manifold. Use ¼-inch drive socket and ratchet, lift the throttle body off the intake manifold. Protect the metal gasket that is in between the throttle body and intake. This gasket must be reused. Install new throttle body in reverse order.
