just bought an 01 F350 drw, cc. with 160,000. since it has so many miles would it be wise for me to have the valves ran? kinda seems chattery when you are slightly on the gas, or could it be the rubber y going to the turbo having a leak?
also heard that the chattering could be dirty injectors. also seems like it takes a bit of fuel to get the turbo spooling while at a constant low rpm, 30 or 40 mph (1200 - 1600 rpm). muffler has been removed also but stock air box and new set of filters
