5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I dont think you seem to understand... the fuel you are using could be causing MOST of your problems.
I understand what you are saying, but the armed forces overseas get the cheapest garbage fuel possible. using low level fuel is pretty much like pouring a bottle of water in your tank with every fill up. gas is too expensive to buy off base. i had a 1995 f150 with a 4.9 L6 (run on damn near anything) and it misfired and had a rough idle if i put the cheap **** in it. I (and most sensible people i know) completely refuse to use lowest level gasoline on base. I know i dont HAVE to run 105 in it, but im not using that garbage they sell.
