It is called pinging and it is bad for the engine. You could try a beter grade of gas for a while or the ignition timing is not right worst case there is to much carbon build up on the pistons and you will have to pull the spark plugs and put in a cleaner MOST of the time it's caused by a bad EGR Valve-Dirty EGR Valve or NO Vaccume going 2 the EGR Valve.LOW Octane can cause it-BUT if u are using the same gas IT'S probably the EGR Valve & if everything else is the same (like Timing) that HASN'T been Changed.Probably a vaccume hose fell off.
