Do a compression test and see if you have adequate pressure.
If not you have ring problems most likely.

My first 94 gt a few years back always fouled out number 4 all the time. Like carbon fouled. Then I tore it down to c what the problem was and the exhaust valve for that cylinder was all carboned up to amd that was the only vavle that was like that. That was b4 I knew anythinh about mustangs. But when I got on it real hard it would black smoke out the pipes so I figured that had something to do with it. But I sold it and never came down to a conclusin to y it fouled out. But I hope u get it figured out. But what trogan said is a good starting place. To try to figure it out
