Hey y’all, I’ve searched- still searching, but in the meantime... my NA 88 FC. Went to start car and while turning over let out a noise that sounded like an intake backfire (Poof, not pop) then a substantial amount of smoke came out right above the trailing coils. Them smoke was very clearly electrical. Now the car runs horrible, won’t idle, rough below 2500/3000 rpm, will sometimes rev up when you throttle down but seems to be in no rhyme or reason. The only thing odd I see is the electrical smoke on leading plug #2 (see pic). I’ve replaced the trailing coil, and tried unplugging TPS, and MAF. All which seemed to make it run different but not well. Haven’t ran into this one yet- rx7s always got something new for ya. Any thoughts, advice? Thanks!
