I will like to know what causes that,because sometimes
it's backfiring on the exhaust pipe but it also don't
accelerating even if you press the acceleration pedal
Fuel system issue could cause a backfire threw the exhaust, like a weak fuel pump, plugged fuel filter or the strainer in the fuel tank, may want to look at the fuel system, may even be leaking fuel injectors. A fuel pressure test and bleed down test would tell the story on that. Also may be a weak spark, check to see if there is a nice white, bluish spark at the end of the spark plug wires, may have an ignition problem like a weak coil.
