Unsure if there is already posts on this, but my titan had been sitting at my parents house for about three years, it would be turned on twice a month. i recently started using it again, i put a rough country 3in lift on it. Had the ses light on, autozone said o2 sensor, bank 2, replaced it, light stayed on same o2 sensor causing it. Few days later, after i let it to my cousin, lost power, truck was still on but no response on the gas pedal, truck is just barley rolling on drive, b-lsd light is on. Had to turn it on and off over and over again to get it home. good thing i wasnt on the freeway. Any clues to whats wrong with my truck? Havent done cat or ecu recalls yet.
