  A: To repair and service the intake manifold we have to do the Fuel System Pressure Release procedure first and separate the negative cable on the battery. Snip the resonator assembly and air inlet hose and cut the throttle and speed control cables loose. Then, remove the electrical connections of the Manifold Absolute Pressure (MAP) Sensor, Intake Air Temperature (IAT) Sensor, Throttle Position (TPS) Sensor, Coolant Temperature (CTS) Sensor as well as the Idle Air Control (IAC) Motor. Remove the vapor purge hose and brake booster hose and speed control servo and positive crankcase ventilation (PCV) hose. Take off the generator and the air conditioning compressor and disconnect the left and the right radio suppressor strap and take off the ignition coil towers. The top oil dipstick tube retaining bolt and ground strap should be removed and also the fuel rail and throttle body assembly with its mounting bracket.
