How do you adjust the idle speed on a 54 plate 1.2 16v corsa?

To adjust the idle speed on a 54 plate 1.2 16v Corsa, you typically need to locate the idle air control valve (IAC) or the throttle body. However, in many modern vehicles, the idle speed is controlled electronically by the Engine Control Unit (ECU) and is not manually adjustable. If the idle speed is incorrect, it might be best to check for vacuum leaks, faulty sensors, or perform a diagnostic check rather than trying to adjust it manually. Always refer to the vehicle's service manual for specific guidance.
