This could also be a sign of the fuel pump failing. However, check the fuel filter first.
anythings possible but 99% of the time a plugged filter or weak/failing pump wont cause the engine to miss and backfire under load lack of fuel usually causes engine die outs and major hesitation
based on my experiences
