Your engine code is "system too lean bank 2" having any engine code, it is possible for it to turn off your stability control, and traction control. I have seen it. Being a v-6, there are 2 banks. This leads me to believe the leak is past your throttlebody, and is only related to bank 2. Obviously right? The most common cause is actually your MAF (mass air flow sensor) however, this reads your air readings before the intake. Its very hard to explain why it can cause a lean code on only one bank. It is the most common cause. Im not saying that is whats wrong. Without actually diaging your vehicle with a proper scan tool, I cant verify fuel trims, and see if bank 2 is lean because a part failed, or because you have an unmetered air leak. I would suggest bringing to your most liked garage of choice, and having it diaged.
