Engine Trouble 2006 W-22 8.1
Left for Florida last night and about a hour into the trip engine started to backfire and hesitated while going up hills. Ran fine on flat road going back home but engine missed a lot. Coach is 10 yea...

This happened twice with our 1992 454 TBI engine. First time it was the pick up coil under the distributer. Second time it was the fuel filter. Symptoms were identical both times. I do expect your much newer engine has the old style distributer.
The prior owner had the #7 or #8 spark wire fail.
