so i have a pretty nice mild built motor and she is running very very rich. its a mass air conversion and has 24lb injectors and a new fuel pump and new o2 sensors and a wideband air/fuel ratio. we also got it tuned with an SCT chip. the car has many other mods if you can see on my profile. but we and my mechanic cannot figure it out and this guy has worked with ford for many of years. any ideas?
