Does it sound like a upper engine knock from a rocker arm, valve or push rod? Check knock sensor. If the check engine light is on have it scanned. If it is upper engine knock I say because it gets loader when accelerating. I would listen to see if its one head or the other. Then pull that valve cover and check things out. If its ping from bad gas then you can put some fuel cleaner in that may help.

It has check engine but the code reader saids its a cylinder 5 but i already change all 6 and just put new spark plug wires aswell. But it keeps making the rattle noise. It comes from the driver seat i believe. Where all the spark wires connect near that area


I would pull that valve cover and look for loose rocker or bent push rod or both.

Can that cause one of the spark plugs to get burned on the side ?


Burned from arcing? I don't think so unless the heat built up. Burned from heat on the electrode tip that goes inside motor? Maybe. Are you using nitrous. Change them out if spark plugs are bad. Use some dielectric grease on boots.
