Question
Hey Tom, thanks for your previous info.   Any idea what i could be looking for on my silverdo 5.3 that would be giving me these codes. P2270 p2271 fuel mix rich or lean. Funny thing in lieu of my p0449 code and this rich lean fuel code my cel was off this morning 24 degrees out.  Fitst time I've seen this.  Came back on after about 20 mins though. All 3 codes putting a big R sticker on my truck.  Thank for your previous expertise,  mike
