I have a question. Few weeks ago, My 2016 Dodge Durango v6 was shaking while driving. My code reader stated P0201 and P0301 codes. I brought it to the dealer and they replaced the water pump and spark plugs. I picked it up and drove less than a mile and it began to shake again. Brought it back and they replaced fuel injector for the cylinder 1. 500 miles later, I smell gas in the cab and under hood. Brought it to another dealer and he said the ring for cylinder 6 was cut. The other dealer says they could not have done this as they replaced cylinder 1. Is this true? Should they have replaced the water pump and spark plugs? Any info would be great. Thank you
