I recently purchased a 95 mustang 3.8l swapped to a 5.0 HO it ran great until last week I went around a corner and it died. Let it cool down and it started ran for a bit then died so I towed it back home to diagnose the issue. I changed the tfi it was fried then I figured change fuel pump, fuel filter, fuses etc. It will now not want to start and if it does I have to throttle through to keep it running. It Smell's really rich so I pulled a plug and it was black so real rich I don't know what else to do im getting fuel and spark just a non running stang. Please help.
