my 2015 2.3 ecoboost turbo mustang seems to ping sometimes under hard acceleration. I get no codes or engine lights, I've had this checked before, they couldn't find anything. what do you think could be my problem? I run 91 octane, the highest octane i can buy in the area, but I tend to buy it the cheapest I can find it, could I maybe benefit from better fuel?
