Accelerated Idle
With engine at normal operating temperature, idling at correct normal idle speed and with transaxle in neutral, proceed as follows:
- Connect an electronic tachometer which is designed to read engine RPM with specified accuracy. Disconnect gray wire which feeds solenoid valve.
- Remove cap nut (E) and hold nut (F) while loosening lock nut (D). Use Allen wrench to turn set screw (C) and adjust to 1500 ± 50 RPM (1350 ± 50 RPM on R16). Retighten nut and replace cap screw. Reconnect solenoid wire.
