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.
Well i just bought a 91gt and when i go full throttle on it, at around 3500 rpms it will start surging, as if the engine isnt getting enough gas, and it wont go passed about 4k. I just got a tune up, changed the oil filter, oil, plugs, wires, but im still having the problem, any idea to what might cause this?
Fuel pump is prolly gettin weak or if you are lucky a filter needs changed.....most likey items at any rate. Runs fine @ lower rpms/power settings right?
