Fuel Cut System

Install tachometer. Tachometer must be connected to proper terminals. See IDLE SPEED & MIXTURE in ADJUSTMENTS article in the ENGINE PERFORMANCE Section.
CAUTION: Some tachometers may not be compatible with ignition system. Consult tachometer manufacturer before connecting tachometer to system. To avoid possible damage to ignitor and/or coil, DO NOT allow tachometer terminal to become grounded.
Disconnect electrical connector from throttle position sensor. Install jumper wire between IDL and E2 terminals on wiring harness side. See Fig 1.
Start engine and warm to normal operating temperature. Ensure all accessories are off. Gradually increase engine RPM. Note fluctuation in tachometer reading to indicate the fuel cut RPM and fuel return RPM. See Fig 2.
Ensure fuel cut and fuel return RPM are within specification. See FUEL CUT SYSTEM SPECIFICATIONS table under FUEL CUT SYSTEM (ALL OTHERS). Shut engine off and disconnect tachometer. Reinstall electrical connector on throttle position sensor.
