just got a 94 GT. It seems to need a little work. It runs good. Did a tune up, cap, rotor, wires, and plugs. It seems to have a hesitation. I have had fox body 5.0's but never a sn-95. Are the cleaning of the sensors the same? Also it has red top injectors in it. I think they are too big. Cobra intake, forged pistons, and I beam rods, some kind of after market cam, gt40 iron heads, roller rockers, intake, headers, msd coil and dizzy. 5-speed. How do you pull the codes?
