My 1996 Chevy s10 chugs at 45- 50 mph. It also studders and chugs when you try to burnout. It makes a pinging sound while hard acceleration. I changed the fuel pump because a mechanic told me too and I just changed the fuel filter because he told me I might try that too Does anyone know what might be the problem? I need some serious answers
