Went to motorhome Rally, started transit all ok ,but wait it started to miss on one cylinder then stopped ,we restarted and it was running ,then it stopped and we cannot start it. It is on the transporter to the dieseil mechanic..Just about to sell this thing as it keep on happening..Any Ideas, We need Help please. Just got text from Mechanic it is sucking in air from some ware.
