Engine Compression Test
Check compression with engine warm, all spark plugs removed and throttle wide open. Ground coil wire from center of distributor cap to engine block. Disconnect one end of duct between airflow sensor and throttle body to disable fuel injection system. Crank engine through at least 6 compression strokes per cylinder to determine engine compression.
