Hey guys i was driving home from work until i hit this lil bump on the road doing like 50 mph, it sounds like my oil pan hit a lil bit like a scrape sound... it was running fine until like 2 min later. it was throwing 1,2,9 codes. which are the 2 o2 sensors and the No.1 cylinder. i was wondering if u guys had any expierence on this. i'm going to be replaceing the spark plugs just incase cylinder 1 wasn't getting spark. any help would be greatly appreciated.
