I have a 2017 GMC Yukon with the 5.3. I have a 3inch exhaust with magnaflow muffler, AFE CAI and diablo sport tune.
I got the P219A code. I figured I might have bad gas so I took the tube off. Code came back. I checked my intake all of the connections are tight there so I’m assuming it’s the O2 sensor but before I dive into that I was wondering if anyone else has had this issue.
