Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Air Supply Valve
Remove air hose from air suction pipe of the air supply valve. Start engine and run at idle speed. Close air suction pipe of the air supply valve. The engine speed will drop, but it should not drop over 30 RPM. Disconnect wire to the air supply valve solenoid and check the air supply to the intake manifold. A large amount of air should be supplied with the wire disconnected.
