I have a 392 and got code P219B, which is the “Air/Fuel ratio imbalance” code on bank 2.

P219A is on bank 1.

I had to chance camshaft and rollers. One of the lobes on the cam was totally worn out.

For you, it could just be a bad upstream oxygen sensor, or clogged injector.

Good luck!

I literally just changed them before the check engine light came on though because my tuner told me too I know they are under warranty I'm assuming change them again and see if it comes back on ?

My injectors we just flow tested maybe 2000-3000 miles ago and upstreams were changed 500 miles ago but they have a warranty
