I have a 93yj that has a problem that i cant figure out... while driving down the road @ 40 mph it loses power and sputters. I thought at first it was a fuel problem ....so i replaced the fuel filter and the fuel pressure regulator....then i thought spark ....replaced the distributor and the coil.....nothing....replaced the map sensor ...aic sensor....temperature sensor ......air charge manifold sensor....any ideals on whats wrong with this 2.5l
