Hello,
Got word from the shop today and they said the coils were cracked?, needed plugs, and fuel pressure was low. I had just recently had the fuel filter replaced by Camping World so either it was the wrong filter , not installed correctly or possible fuel pump. Not sure but I think the fuel pump is in the tank unless an in-line one can be installed if it is the fuel pump. The rig only has 41000 miles on it and hard to believe I have these type of problems already.
