ENGINE COMPRESSION
Check engine compression at normal operating temperature with all spark plugs removed. To prevent damage to catalytic converter, make tests quickly and only when necessary.
Note. Compression specifications are not supplied by manufacturer. Difference between cylinders must not exceed 25%.
