2001 Jeep Grand Cherokee Limited V8 4.7L the Engine Light is on, the Check gauges light is on, it read: P0308 Cylinder 8 Misfire Detected, and P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2). I replaced the spark plug coil on plug 8, replaced upper O2 sensor...lights still on and runs rough...what could it be?
