    Pull the OBD2 trouble codes to see what system is damaged or not functioning. I don't know if there's any fuel low enough octane to make that engine ping. It will perform very badly on 85 octane, but not ping.

    Have a mechanic check the timing marks for the camshaft and crankshaft to find out if the motor jumped time.

      Since it has a timing chain, jumping timing might be due to a broken tensioner. If the timing changed, get to a mechanic and do not try to adjust the ignition timing or it will get worse.
