INFINITI I35 DEALER PROBLEM

2002 Infiniti I35

Engine Mechanical problem
2002 Infiniti I35 6 cyl Front Wheel Drive Automatic 170000 miles

My 2002 I35 Infiniti started to ping about 2 years ago. I took it to the dealer and their cure was to retard the timing by 2 degrees. The only thing that accomplished was a reduction of gas mileage. I would appreciate any advice on how to fix this finally. Thanks.
