I finally got around to putting a wideband and analogue AFR gauge in my car. When I idle, it's a healthy 14.5ish, when I accelerate it goes to 10 (my gauges limit), and when I let off the accelerator it got to 20 (my gauges limit).
Other than than, when the car is cold it will hit fuel cut if I even try and enter boost, until it hits normal temperature.
Cleaned MAF and IAC, hasn't done anything.
Suggestions? Maybe o2 sensor?
