Hello Guys and Gals,
I am new to the forum here and I am coming for guidance. I have a 2017 Silverado 4x4 crew cab 1500 with the 5.3L. I currently have 90k on her and about 3 months ago my check engine light came on so I plugged it in and got code P219A (Air Fuel inbalance Bank 1 Sensor 1) I decided just to replace the upstream O2 sensor and cleared the code. A few weeks went by and I thought I had it fixed. After a month of driving, my check engine light came back on. So I replaced all of the 02 sensors and cleared the code. I hooked up my buddies snapon computer and drove for 3 days to run a live scan and it all appeared good(No longer have scanner so I cannot answer any questions about what it said). Yesterday I got in and started down the road and my light came back on. I went to work and when I stopped to get the kids, I shut off the truck and when I fired it back up the light was gone. I jumped in the truck today and within 2 miles the light came back on.

Guess the question I have is what in the hell else could this be, I am sure it has been posted before, but I was unable to locate a topic about it

Thanks
JoeDee
