mutiple misfire code/check engine light on

Misfires can also be caused by fuel delivery or insufficient valve clearance ( but your engine has hydraulic self adjusting valves). A professional grade scan tool shows misfire count showing which cylinders are failing, and show fuel trim figures, and air flow into the engine, on Jaguar, Lexus, and Nissan when the air flow meter fails it dos not tell the computer the proper amount of air being drawn into the engine and the engine runs a lean misfire condition.
