so I have a s13 with a black top sr mostly stock other than FMIC ISIS turbo manifold exhaust and SAFC.(yes I know SAFC is junk came with the car) so ive owned the car for about a year and a half and about 6 months into owning the car I got this weird break up that would only happen under a load anywhere from about 5500-6000 or if I stomped on it, I can hit limiter if I baby the throttle. anyways I did a boost leak test, no leaks, changed plug gap to .032, no results, new isr coil pack just one, ran it threw all cylinders no difference. so now my new issue is, that im running dumb rich blowing tons of black smoke, but afr at idle read 14.9 but SAFC wont give me any other screen other than these patterns EX. (-,/,|,\) the only information it gives me is my knock sensor screen then I hit the center button again and it shuts off. so just for shits and gigs I put new plugs in cleaned the MAF and cleaned the injectors. oh P.S. I have fuel in my oil.... sooo im thinking safc is junk but does that explain why I have fuel in my oil?
