Having an issue with an s13 redtop in an s14
Car runs perfectly fine while it is cold and warming up however after about 15 minutes of driving it will do this
Once car is warmed up if i rev it above 3k and then it?ll want to die when it comes down and won?t let me accelerate almost like it?s in limp mode, unplugging cylinder 1 returns it back to normal and it runs perfectly fine, if I rev above 3k again it does the same thing

Issue started randomly one day on the freeway, it just backfired super loud and bogged down like that
