2007 Chevrolet Equinox Mass Air Flow Sensor

You will need to remove the air intake duct, inspect the Throttle Body bore and the throttle valve plate for deposits, then clean the throttle body bore and the throttle valve plate using a clean shop towel with GM top engine cleaner, GM P/N 1052626 (Canadian P/N 993026) or AC-Delco Carburetor Tune-Up Conditioner, P/N X66-P, or an equivalent product. Finally, you can install the air intake duct.

You will need to disconnect the manifold absolute pressure (MAP) sensor electrical connector, remove the MAP Sensor retaining bolt and bracket, and next remove the MAP sensor and the MAP sensor port seal if it is still retained in the intake manifold.

You will need to drain the cooling system and remove the upper Intake Manifold, then remove the heater inlet pipe, disconnect the radiator inlet hose from the thermostat housing, remove the fuel rail assembly and the lower intake manifold bolts, then remove the lower intake manifold from the engine. If replacing the lower intake manifold, you should remove the thermostat and housing. Then you can remove the rocker arms and push rods, and the lower intake manifold gaskets.
