Air Injection Pipes and Valves

Air injection pipes and valves are part of the emission systems of a car. They are used to inject additional air into the combustion camber. If you are having problems passing a Smog test this may be part of the problem.

Idle Control Valves

Similar to the auxiliary air valve, the idle control valve control valve adjusts and maintains the proper idle for the car whether it's cold or hot. Based on temperature sensors in the engine, the valve opens automatically to allow more airflow into the engine while cold, essentially like a choke on an old carburetor, keeping the engine supplied with more air until it reaches a certain temperature. If the unit goes bad, it can cause rich running, idle fluctuation and hard starting.
