i just bought a 99 yukon slt 4x4. 178000 miles and new transmission. the check engine light is on and says bank 1 sensor 1 no activity detected. so i get under there and look the o2 sensor isnt ever plugged in and i dont see a plug for it anywhere i was wondering if someone could shoot me a pic or ideas of the plug-ins location or were it goes or something im getting 15.3 mpg constantly. this is my first yukon or tahoe so far i love it.
