When I press gas truck sputters loud and gets very little power it accelerates very slow and I have to let off gas to get it to go faster. When sputtering it also sort of jerks like it not getting fuel right or something, I've been told it could be fuel filter or injectors but then another person today told me to check exhaust for leaks. What should I do I don't have money for mechanic so need to to repair it myself.
