Hi, pano ba i adjust yung air and gas ratio ng kia sportage naten? pina-emission test ko sya last time kaya lang hindi sya pumasa. nag tune up, oil change, at pati overhaul na rin ako, gusto ko sanang i adjust yung air and gas ratio kaya lang computerized ata yung carborator ng sportage 96 e. nga pala gasoline type sya, 2.0 DOHC. tsaka isa pa palang napapansin ko is medyo humina yung hatak nya compared date...

any help would be much appreciated!
