P0301 P0303 and P0305 are all cylinder misfire codes for cylinder 1, 3, and 5 which are the rear bank of cylinders. We may have an engine or vacuum leak causing this or faulty ignition coils. The P1313 and P1316 are for misfire rate high. P0420 is cay converter efficiency as the cat could have been damaged from the misfires.
