USUALLY THE IGNITION COIL PRIMARY RESISTANCE BREAKING DOWN OR CONNECTION PROBLEMS CAUSE THESE CODES. EXCHANGE THE COILS FROM THE TWO AFFECTED CYLINDERS #3 AND #6 TO TWO OTHER CYLINDERS AND SEE IF THE CODES MOVE WITH THE COILS. THIS WILL CONFIRM COILS ARE FAULTY AND YOU CAN REPLACE THEM. IF THE CODES DON'T CHANGE WITH THE COIL POSITION THEN YOU HAVE A POSIBLE WIRING OR CONNECTOR PROBLEM. CHECK THAT THE TERMINALS INSIDE THE HARNESS SIDE OF THE COIL CONNECTORS DIDN'T GET STRECHED OUT AND LOOSE.
