    2012 Buick Lacrosse P2188, P2190 [OBD2 Data] [advice needed]

    Hi all! In order to save time, I will first upload pics of OBD2 data. I am not-technical at all. Trying to help my father get this problem fixed. Would greatly appreciate your help. (Btw - I checked the air filter, which sounded easiest, looks clean)
