Hi guys, ive just done a ls1 coil conversion on my s2 rb25. I does idle alot smoother and dirves almost like new, however there is still a slight miss around 4500 then accelerates then misses again at random after that till redline. My fuel pump isnt the issue an im running afr of around 10 to 11 at wot. Following mods are 3 inch dump and exhaust, fmic with 300zx plumb back bov, stock ecu turbo and injectors and a greddy style forward facing plenum, running 6psi as anymore and the missfire becomes more violent. Ive checked for leaks/holes in the pipes and silicon connectors but nothing found. Im lead to believe it maybe my cas?
