What makes up the throttle body and idle air?
IAT – Intake Air Temperature – Measures the temperature of the air the engine is intaking. IAC – Idle air control – Controls the amount of air the engine is intaking while it is idling. Throttle body – Responsible for regulating flow of air into the engine as you press the gas pedal.
Where is the idle air control valve located?
The idle air control valve (IAC) is usually connected to the throttle body next to the intake manifold. Consequently, it is the engine control unit (ECU) that manages all the functions of the valve.
Why is my idle speed control valve not working?
One common problem is a buildup of carbon or fuel varnish deposits in the idle speed control valve. The cure for this condition is to clean the valve, with some aerosol throttle cleaner or engine top cleaner. Disconnect the air intake ductwork from the throttle body.
What does MAF and idle air control do?
MAF – Mass Air Flow sensor – Monitors the amount of air the engine is intaking. IAT – Intake Air Temperature – Measures the temperature of the air the engine is intaking. IAC – Idle air control – Controls the amount of air the engine is intaking while it is idling.

Can a dirty IAC cause a rough idle?
A dirty IAC can cause a rough idle. A dirty throttle body can harm performance and cause rough engine operation. When the throttle body or iac is removed a new gasket must be used to properly seal the connection to the intake.
Can a dirty throttle body cause rough idle?
The vans require removal of alot more stuff just to access the throttle body. A dirty IAC can cause a rough idle. A dirty throttle body can harm performance and cause rough engine operation. When the throttle body or iac is removed a new gasket must be used to properly seal the connection to the intake.

Can a GM idle air motor be removed?
When the throttle body or iac is removed a new gasket must be used to properly seal the connection to the intake. GM idle air motors are generally mounted on the throttle body and can be cleaned without removal from the throttle body. This means one less gasket and a lesser chance of creating a vacuum leak.
How does a GM throttle body relearn procedure?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position.
