Well Im Fairly new here and did alot of research prior to posting this but apparently not enough. Recently I did a 626 manifold swap removed the butterflies jb welded the holes for the rod and removed the little lip inside i did not port it. I then installed the manifold. the car idles fine but once I get on the my a/f read below 10 and it runs extremely rich. When Installed the manifold I did use some of the sensors of the 626 manifold dont know if that mattered. I have then replaced both o2 sensors coolant temp sensor check for leaks new plugs the whole 9 yards. I cannot find whats making it dump so much fuel. Its driving me crazy has anyone ever had this problem? Is it possible there is a boost leak i havent found yet? I did do a leak test and found nothing I have no check engine lights either and I no longer own the msp manifold. It also has coil conversion.
