Intake Manifold

To remove the Intake Manifold, you should ease the fuel pressure and disconnect the negative Battery Cable. Drain the engine coolant and remove air cleaner assembly. Next, you will disconnect the ground wire from the Intake Manifold, the fuel injector connectors, the manifold absolute pressure (MAP) sensor connector, the throttle position (TP) sensor, the idle air control (IAC) valve, and the evap canister purge valve. Unplug the wiring harness from the retaining clamps, detach the fuel return and fuel feed hoses from a fuel railvmlinux. Undone the coolant hoses from the Throttle Body and Intake Manifold and the canister purge hose and brake booster hose from the Intake Manifold too. Take off the seven nuts and three nuts keeping the Throttle Body and wire clamps all connected to the Intake Manifold, and pull out the accelerator cable from the Throttle Body. Also remove the Intake Manifold Gasket from the cylinder head. For installation, mount a new Intake Manifold Gasket on to the cylinder head, and then set the Intake Manifold with the tbi unit and wire clamps, tighten the manifold with two nuts and seven bolts at 23 nm (17 ft. Lbs.). The problem is that th gear cable slides over the lever on the steering column. The cable spasm commonly groups between this lever and the lever located under the assembly of the gear shift lever which has the stick shift pattern shown on it. Put the fuel return and fuel feed hoses back to the Fuel Rail, attach ground leads on Intake Manifold, fuel injector connector, and map sensor connector, throttle pos. Sensor, iac valve, and evap canister purge valve. Secure the wiring harness to the retaining clamps, fit the accelerator cable from the Throttle Body, and set the accelerator cable play within specifications. Reconnect the Throttle Body to the air cleaner assembly, reconnect the negative cable to the battery, and refill the cooling system and then finally to start the engine and check if there were any fuel and engine coolant leaks.

Drain the engine coolant and remove the air cleaner assembly.
