2005 Suzuki Forenza • 4 cylinder 2WD Manual • 87,000 miles

2005 Suzuki Forenza - started running rough when starting after having sat for hours, would clear up in less than a min, then check engine light would flicker then go solid, changed gas problem went away for a couple of day, also added gas treatment, now light is not lit, but is bucking like crazy after starting after car has sat for hours. Is this bad gas? Spark plug, fuel injectors? Ideas.
