running rough/ sputter
I have a 97 350 7.3 4x4. I had a bad rear tank so i replaced it. now i have a sputter in the engine.
The rear tank stated to go dry so i switched it to the front tank. The sputter stopped. Now when i accelerate i get the sputter again (not that bad but noticeable) at about 20 mph-35 mph and 1500 rpm- about 2200 rpm.
i replaced the fuel filter today, checked the tanks vents, and it has new gas caps and it still does it!
Any suggestions of what to look for now?
