Hi joydeanj!

Umiilaw mostly ang "check engine" warning light pag ang problema ay related sa exhaust/emission control, and possible causes may include faulty spark plugs, high tension wires/cables, lambda/oxygen sensors, barado catalytic converters, may air leak sa intake manifold system at kung kinakapos din ng fuel supply. Since may kasamang jerking o kadyot during acceleration, a visual check of the above may help otherwise have it scanned for stored DTC's in your engine control unit...
