SAAB Dashpot: Adjustment
- Warm engine to normal operating temperature and check ignition timing and idle speed. On Turbo models, disconnect EGR. On non-Turbo models, disconnect and plug distributor vacuum advance.
- Rotate throttle lever and check that dashpot rod strikes stop at 2100-2300 RPM on Turbo models or 2400-2600 RPM on non-Turbo models.
- Raise engine speed to 3000 RPM and measure return time to idle. If less than 3 seconds, loosen lock nut and rotate dashpot closer to throttle stop.
- If more than 6 seconds, loosen lock nut and rotate dashpot away from throttle stop. Tighten lock nut and repeat test.
