I apologize, I misread the scan tool. The codes I got are P015B, which is a bank one sensor one oxygen sensor experiencing a "lean to rich" delayed response. The other code is P219A, which is an air-fuel ratio imbalance. I've replaced the MAP sensor and the upstream oxygen sensor on bank one, but I still am getting these codes. I had read online that a cold air intake could possibly be letting too much air in for a factory tune to support, so I cleared the codes and put the stock air intake back on yesterday. I'll run it like this and see if the codes come back, but in the meantime, I'm open to any suggestions. Thanks!

I keep getting the codes P106B and P2015 on my Silverado. I've already replaced the MAF sensor and the bank 1 upstream O2 sensor, but the codes still come back after being cleared. What else should I be looking at to fix this? I just got the truck a couple of weeks ago, but of course there isn't a warranty. Any help that can be given is appreciated! Thanks!
