5.3 had a bad temp sender and fuel pressure regulator when I bought the truck. When I replaced the pressure regulator ugly filth poured out so upon inspection fuel filter was replaced also. New plugs and wires were added and this brought her around and drove fine for about a week. It then set a 307 code so I pulled the plug to find it extremely flooded so I replaced the injector and my miss disappeared.I got about 4 days out of that injector and had to replace it again. Driveability returned and about 200 miles later I tried to start it. It cranked but stopped abruptly and would only engage starter and kick out. Pulled #7 plug only to find the same fuel soaked condition. Rotated and replaced plug and she runs but the miss returned. The motor is a little tired. I get 130lbs in each cylinder so I'm hopeing maybe you can point me in the right direction.
