you have to give more info, man

did it start after you changed something? is it happening on acceleration or decel? what color are the flames? does it happen when its warm or cold?


it could be anything from too much fuel or not enough or spark happening at the wrong time, valves, air leak, you need to give you info and we can narrow it down.
