Recently and very abruptley my truck has shown a significant decrease in gas mileage, it sputters while idleing and struggles to pick up speed. At first I thought it might have been the fuel filter but after replacing it twice and showing no change it can't be that. First, is this most likely a fuel pressure issue? If so, what should I be doing next and so on... If I am to look for any guages, do any of them have unusual placement?
