I have a friend that installed a JR kit on a 1st gen B16 and it's killing the plugs, it's running so rich. We've tried everything that we can think of. This is at idle not even driving it around. So what we have resulted to, is convert the fuel system back to stock as if it were NA and it's still killing the plugs at idle. All we want to do is get the car to idle. Somebody please give us some ideas.[ Thanks.
