Question

Quizplus · Accepted Answer

Sequential fired port fuel injection fires each injector separately, following the engine firing order, which allows for better fuel efficiency and easier tuning than simultaneous double fired or grouped double fire options. Throttle body injection is a different type of system that injects fuel into a single throttle body, rather than individual injectors.
