    I’ve been reading a p107 lean mixture. What happens is when its idling it does fine for the most part, if you have it idling for tp long it will stall out. When you try to press on the gas it almost seems like its blowing the air instead of sucking it. And that’s when it’s in park when your in drive and you press on the gas it it starts to build power for a instant then all of sudden no power. You have to let up on the gas pedal and repress gently. And redue sometimes several times before the engine gets back in the firing motion. But a lot of the time it almost sounds like it’s not firing on all cylinders either

    Do you mean P0171? Have you smoke tested? What are your fuel trims at idle, 2500, & 4000?
