Yes, many Hilux owners have found that replacing worn-out spark plugs o r faulty ignition coils resolved misfires and hesitation issues. Symptoms like rough idling, sluggish acceleration, and poor fuel efficiency often indicate ignition problems. Using high-quality OEM o r iridium spark plugs can improve performance and longevity. In some cases, if the misfires persist, checking and replacing ignition coils, inspecting wiring connections, o r cleaning the throttle body may also be necessary for a complete fix.
