Throttle Body: Service and Repair
Throttle Body Assembly
Cleaning on the Car
The throttle bore and valve deposits may be cleaned on-vehicle, using carburetor cleaner and a parts cleaning brush. Do Not use a cleaner that
contains methyl ethyl ketone, an extremely strong solvent, and not necessary for this type of deposit.
CAUTION: The throttle body should not be soaked in an immersion-type cleaner, loss of factory installed lubricant could result.
The Throttle Position Sensor (TPS) and Idle Air Control (IAC) valve should "NOT" come in contact with solvent or cleaner as they may be
damaged.
