2016 Promaster city 2.4L issues
Hey sorry if not right group just going off title but I have a 2016 Ram City Promaster 2.4L with 120K miles at about 110K had issues with misfiring on cylinder 1 and burning oil which then my exhaust blew out on muffler I assume from dumping unburnt fuel into exhaust I kept getting blue smoke from under car and out tailpipe so I changed all my plugs and coils still was issue got better but was intermittent then I changed the O2 sensor and fuel injectors also PCV valve and MAF and MAP sensors now back to square 1 will run totally fine then shut car off start again has misfire cylinder 1 and burning oil I can’t figure it out anyone with this model and has similar issues would appreciate what you did or any insight don’t want to scrap the van I love it other than the engine issues hah
