Disconnect the cable from the negative battery terminal. Remove the air intake duct assembly. Remove the PCV valve and hose connecting the intake manifold to the valve cover. Remove the upper intake manifold (1997 and earlier MFI models only). Tag and disconnect all electrical connectors at the throttle body and manifold. Remove the fuel lines and any wiring attached to the lower intake manifold. Remove the fuel rail bracket. Remove the spark plug wires from the coil pack. Mark the spark plug wires for reassembly. Pull them up through the intake manifold and lay them over the left side of the engine. Remove the bolt holding the heater hose tube to the right rear of the manifold. Remove the mounting nuts and separate the manifold from the cylinder head. Remove the EGR tube for cleaning. Remove the old gasket and transfer all components still attached to the old manifold to the new one. Before installing the manifold, clean the cylinder head and manifold gasket surfaces. Apply a thin coat of RTV sealant to the intake manifold and cylinder head mating surfaces. Place a new gasket on the manifold, hold the manifold in position against the cylinder head, and install the mounting nuts finger tight. Tighten the mounting nuts in several steps and in the correct sequence. Install the remaining components in the reverse order of removal.

The PCM monitors various engine parameters via sensors and briefly energizes the fuel pump upon ignition.

The final step is to install the remaining components in the reverse order of removal, ensuring everything is reassembled correctly.

Follow similar steps starting from removing the upper fan shroud, air cleaner assembly, draining the cooling system, and disconnecting the upper radiator and heater hoses. Unbolt the EGR valve, move heater hoses, and remove the ignition coil. Remove the small brace from the air conditioning compressor to the intake manifold and turn the engine to TDC for number 1 piston before removing the distributor.

Ensure that the cylinder heads, block, and manifold mating surfaces are meticulously clean, remove any sealant and old gasket material with a gasket scraper, and wipe the surfaces with lacquer thinner or acetone. Cover the lifter valley with shop rags to prevent debris from entering the engine, and clean the bolt holes using a tap and compressed air.

Complete the reinstallation steps in reverse order, start the engine, and carefully inspect for oil, vacuum, and coolant leaks at the intake manifold joints.
