Fuel to rich/black smoke

93foxbody2.3 · 05-27-2009

How do I correct the rich fuel problem I have. I have 17 lb fuel injectors in it, and hopefully I can get a 5.0 MAF on it with 3" tubing going to the throttle body. Is it as easy as an adjustable fuel pressure regulator or is it something I can tune with a screwdriver or something like that?

Check engine light on? What are you getting for a code, it must be giving you something if it's running that rich. And no there's nothing, you can adjust with a screw driver it's fuel injected not carburated. You could have, a bad O2 sensor. First off what have you changed, before we try to troubleshoot this issue, Mike? SCT Tuner.

The check engine light comes on and goes off periodically, but that's from this thing with a wire that went to the air box. I don't know what codes it's throwing. I have another 02 sensor if that's it. And everything I have done to the car is in my sig.
