Okay here is my problem, as some of you know my car is running way to rich, I checked my plugs the other day when my lude would not start and they were covered in fuel. I noticed my fpr, it is definately turned up way high. My question is without having to spend almost two hundred dollars to go have it tuned again, will turning it down help my rich problem? How much could I turn it down without losing performance. The back of my car is black because I'm so rich. Any suggestions would be appreciated. Also I have a vafc should I have it leaned out that way rather than the fpr? Thanks
