ENGINE COMPRESSION
To check engine compression, bring engine to normal operating temperature. Disconnect distributor electrical connector(s). Remove all spark plugs. Remove air intake hose from throttle body. Fully open throttle. Ensure engine cranking speed is at least 250 RPM when measuring compression.
