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 have a 88 gt, converted to mass air. Car ran fine until i put new parts on it. I put upper and lower intake, #24 injectors, 190 lph pump, adjustable fuel pressure regulator, tune up, mass calibrated for injectors and 70 mm throttle body and egr spacer. Car revs up fine but when I drive it, it has a miss like the plug wire is crossed. I've checked 5 times and its right. I was wandering what happens if a fuel injector is bad it it will miss like that, they were used injectors. Also what fuel pressure should I run? Any help would be appreciated.
They didn't happen to be 24's out of a cobra did they? Those are low impedance and won't work with the factory GT EEC. You would have to switch to the Cobra computer.
