OK. I admit, I haven't driven a 4 cyl in over 20 years. My brand new 2016 Frontier has a slight ping, or maybe tick is a better word(hard to describe) when accelerating. It's slight, but I do hear it and don't know if this is just a normal 4 cyl engine sound accelerating...or something I should have checked out. I don't hear it when parked and give it some gas...at first I thought it might be the sound of a slight exhaust leak.
