Sprinter V6 Engine Rough at Start

2020 Sprinter Navion 3500

Purchased May 2022 with 31K miles in Florida.

Drove from Florida to Quebec City (1800 miles) with arrival 11 July - No issues.

Vehicle parked for two (2) weeks.

Yesterday, started engine as usual and engine idled very rough

for at least two minutes. Apparently not firing on all cylinders. Then smoothed out to normal operation. Ambient temperature was 84 degrees F.

Anybody out there in Sprinter land have any ideas/thoughts/comments about this??

Please advise,
cthiggy

Could be a bit of moisture in the fuel system. You may want to have the fuel filter changed, perhaps add some Heat-type fuel additive to the fuel tank to clear out things. FYI, I always top off my fuel tank before putting the rig into storage to diminish the condensation that might collect in the tank.
