So took it into to one of my local dealers, quoted this TSB and asked them to check the diagnostics. They kept it for 2 days, called me and said "we know it is misfiring, but until we get a check engine light/code thrown at us, we aren't going to throw parts at it..." So any advice what my next plan of action should be? p.s. Had a friend replace the spark plugs, but not ignition coils. Could it be coil issue?

What is the estimated costs of having this done? My 2012 Journey V6 is doing this exact shutter after coming to a stop and transferring from brake to accelerate.
