Truck sputters and stalls

Have you or a local technician near you hooked up a fuel pressure gauge to the fuel rail? Getting real data is far better than a guess. I wouldn't guess at "knock sensor" either -- even if there is a related code set, it means check the system out and figure out the whole picture, don't just guess at a single clue or code or symptom. www.repairpal.com/repair-shops
