I recently inherited my older brother's 2013 Dart. He has always had issues with it and its my opinion that's because of lack of maintenance (he was in the Navy and was on multiple deployments of 6-9 months so I'm giving him a pass). Its been sitting in my garage for months since his funeral and I finally decided to take it to the dealer to get it diagnosed. I spoke with the service advisor yesterday and he told my the one misfire code was because of the Cylinder 2 VVT Oil Supply Solenoid. Now I have gone down the rabbit hole and have found various threads with potential solutions. I'm thinking I'm going to try the ATF+4 trick and see if that works. I will obviously check the connectors as well. Does anyone have any other suggestions or possible solutions ? All of the threads I've seen have been for the 2.4L and 2.0 engines. @alpinegreenneon please help !
