Fast Idle Air Valve: XL-7

NOTE: This model uses thermo wax to control an air bypass valve inside throttle body.

Ignition off, with coolant temperature at 75-78 °F (23-26°C), disconnect Idle Air Control (IAC) valve. Start engine, check that higher than normal idle speed exist. As engine coolant temperatures raise, fast idle speed should gradually reduce. If results are as specified, fast idle air valve is in good condition. If not as specified, valve could be faulty or coolant passage could be blocked.
