- Warm up the engine to normal operating temperature (cooling fan comes on).
- Turn the ignition switch OFF.
- Remove the intake manifold cover (see step 1 of «CYLINDER HEAD COVER REMOVAL»(ref-173867-S11518418012005032300000) ).
- Disconnect all four injector connectors.
- Start the engine, and let it run until it stalls.
- Remove the four ignition coils (see «IGNITION COIL REMOVAL/INSTALLATION»(/honda/civic/vii-2003-2006/remont/ignition-system/#ignition-system-hatchback) ).
- Remove the four spark plugs.
- Attach the compression gauge to the spark plug hole.
- Open the throttle fully, then crank the engine with the starter motor and measure the compression. Compression Pressure: Above 930 kPa (9.5 kgf/cm 2 , 135 psi)
- Measure the compression on the remaining cylinders. Maximum Variation: Within 200 kPa (2.0 kgf/cm 2 , 28 psi)
- If the compression is not within specifications, check these items, then remeasure the compression: Damaged or worn valves and seats Damaged cylinder head gasket Damaged or worn piston rings Damaged or worn piston and cylinder bore
