sr20det no power and rich

[EarlsWorld]

so i have an s13 silvia and its got a sr20det. its running super rich (smoking and exhaust flames), it has a really bad idle and sometimes so bad that it stalls out, and 0 power what so ever. i was thinking either a massive boost/vacuum leak or a bad maf. whats your guys ideas on what it might be?

I'm experiencing the same issue, I've checked for leaks and found nothing pulled my valve cover this morning and found this. https://uploads.tapatalk-cdn.com/20170716/3d8eee0aba6d193daa37a45fa111efbe.jpghttps://uploads.tapatalk-cdn.com/20170716/982a06021afacc131270083348e8d81d.jpg

that looks gnarly man! ill have to pull mine and check it out, but i think that mine might just be a bad MAF

Yea man, is off 1 link, it will run but it runs crappy. My first thought was maf as well but unfortunately not. Check your timing for sure man. The afr idles at 14.0-15.0 jumps around and at wot it dips below 10. It stumbles under boost really bad and when I come to a stop it try's to die, sometimes it will die unless you use the throttle to keep it alive.
