To adjust the idle speed on a 1997 Jaguar XJ6, first ensure the engine is at normal operating temperature. Locate the idle speed adjustment screw on the throttle body; turning it clockwise increases idle speed, while counterclockwise decreases it. Use a tachometer to monitor the RPM and adjust to the manufacturer-recommended idle speed, typically around 700-800 RPM. After adjustments, clear any diagnostic trouble codes if present, and ensure the throttle response is smooth.
the engine runs at a faster rate than when the idle speed is lower.

To adjust the idle on a 1990 Jaguar XJ-S, first ensure the engine is at operating temperature. Locate the idle adjustment screw on the throttle body and turn it clockwise to increase the idle speed or counterclockwise to decrease it. After making adjustments, allow the engine to stabilize and check the RPM with a tachometer. If necessary, repeat the process until you achieve the desired idle speed, typically around 600-800 RPM.
