I think you mean 2.5 liter (not 2.6, which we corrected)… if so, how rough is it? How many miles does the car have on it?
If it’s a little, then it’s fine since I’ve seen the 2.5L LCV I4 start a bit rough… and that’s ok as it’s normal operation. Also, if the car isn’t broken in yet, then it might start rough for the first thousand miles or so.
