wasup peeps. my engine pings and knocks,i changed the gas and put a can of power boost. if it keeps happening what can i do? thanks....

 

Did you just put on a new tank of gas when this happen?

If so, that's probably just a case of bad gas. It does happen you know. If it is recurring, though, then you might have other problems. Or just extremely unlucky and keep getting bad gas! In which case I strongly suggest you avoid any casino or buying any kind of lottery!
