Hey guys, first post here

S15 sr, brand new 750cc, z32 maf, spitfire coils, new plugs.

Car runs fine and I'm running 20-22 pounds right now. On my old setup I was having the same problem where I'll just be driving around, no problems, and bam I'm on 3 cylinders for a couple seconds and then it's gone. Would this be a sign of a coil going bad? I was playing with my Greddy Profec last night so I was able to catch a glimpse of afr when it happened. Once it was a little richer, once it was a lot leaner(when it started misfiring) but I find it hard to believe it's my injectors as I got a new harness when I bought the injectors. Any info would be much appreciated
