I have a 94 coupe(D16z6) and im running too rich, there is no check engine light or anything, car runs just fine but i know im running rich becasue black smoke comes out of the tail pipe at 2 step, I just put in a walboro 255 fuel pump im just started noticing it lately but im not sure if just started after the fuel pump or not, im going turbo this weekend coming up im goin to be running a FMU and missing link, will i still be running rich if so how can i fix this problem??
