2002 camry 4cy. check engine light is on code P0301. Already swap the ignition coil and spark plugs with other cylinders but misfire still on the same cylinder. Freeze frame data shows short term fuel trim reading (0.8),(10.9),(11.7) & long term fuel trim (16.4),(19.5),(19.5). these reading were taken on three different days. What next to check?
