This Preliminary Information communication provides information to the technician that some vehicles may have a Service Engine Soon lamp, engine misfire on cylinder 1, 4, 6, or 7 and/or tick noise. Technician will follow service information diagnosis first. If service information diagnosis does not isolate the cause of this concern perform a cylinder deactivation active fuel management system compression test in service information. If the running compression of the misfiring cylinder stays below 25 Pounds per Square Inch regardless of the active fuel management solenoid being commanded on or off, an active fuel management lifter is mechanically collapsed/stuck or unlocking as soon as the engine is started. Replace all active fuel management lifters, and all plastic lifter guides. Also perform the cylinder deactivation active fuel management Valve Lifter Oil Manifold Diagnosis and Testing in Service Information. If it isolates a concern with the Valve Lifter Oil Manifold, replace it and reevaluate the concern. The active fuel management lifters can also be monitored for proper operation by carefully inspecting the cylinder 1, 4, 6, and 7 rockers and valves while cranking or briefly and safely running the engine with the valve covers removed.
