I have a Cat C-7, 330hp in an O4 Journey, chassis date is Oct 03. It has one fuel filter/water seperator, frame mounted. The coach has 22K mi. on it. This last week I changed the fuel filter with a genuine Alliance part and the air filter assembly was changed a month ago.
Occasionally, upon acceleration from a standing start, the engine will sputter, coach will move, but crawls until after about 30 seconds to 1 min. then it kicks in and runs perfectly.
I use Lucas fuel treatment at every fill up.
Any thoughts to what it could be?
