Several possibilities; faulty / worn spark plus, faulty / worn spark plug wires, faulty / clogged air filter, dirty throttle body, dirty mass air flow (MAF) sensor, dirty / clogged fuel filter, tire pressure too low, tires not aligned properly, brakes dragging, fuel system leak - to list a few factors.
