Before attempting to remove the intake manifold, loosen the fuel system pressure and, disconnect the negative terminal of the battery. Remove the air intake duct from the throttle body, remove the brake booster vacuum line from the intake manifold and disconnect the electrical connectors of the electronic throttle body. Remove the PCV hoses, and loose the quick-connect coupling on the EVAP line at the intake manifold. For 4.6L Sedan, Disconnect the drive belt, no power, disconnected the Fuel Rail Pressure and Temperature sensor connector, no fuel, took off the fuel rail injectors. Remove the electrical connector from the Charge Motion Control Valve, this is located at the rear of the intake manifold, it will be easier to do this if you unbolt and move the manifold forward. For the 5.0L engine, it is necessary to remove, if installed, the strut tower cross brace, to take off the engine cover, to disconnect the fuel line connected to the fuel rail, to pinch the heater hoses from the support brackets and, at last, to remove factors fastened to the support bracket. Raise the fuel rail insulators and remove the electrical connectors to the fuel injectors; however, do not remove the fuel rails, then remove the fuel rail bolts. For all engines, turn out the intake manifold bolts gradually in the reverse sequence to the tightening sequence until they can be turned out by hand. On 4.6L engines, also push the intake manifold assembler ahead and remove the CTsensor jumper harness connector. You can use a small amount of force to lift the intake manifold from the cylinder heads and remove the intake manifold gaskets and ensure dirty and sealant from the sealing surface has been cleaned out. Using some shop rags, or black jogging duct tape, cover the intake ports to avoid the occurrence of debris in the engine. In installation, if you are replacing the manifold, then shift all fixtures to the new manifold, fix new O-rings on the manifold, then fix the manifold gently and neatly such that the O-rings do not get distorted, apply and tighten the manifold bolts in the right sequence. Perform the remaining steps of the installation as those steps were removed, being careful not charger electrical harness is in the way of the Charge Motion Control Valve actuator rods.
