P219A keeps coming up after multiple times in the shop.
Anyone have any ideas.
Replace all 02 sensors and cat
converter.

This could be a few things.. When was the last time ugs were done? This is one of the codes I got when my cam ate its self.

P219A is a air/fuel ratio imbalance. So basically anything that is related to the air/fuel mixture can cause it. Ignition/fuel system. Sensors or engine mechanical issue as well. Could also be a wiring or PCM fault.

I keep getting 219B which is the opposite bank of cylinders. It's come and gone for a couple months now.

There is a thread on here where the intake manifold bolts back off as well. This allows more air to enter one side more than the other making balance issues. Check ur manifold bolts.

I missed that somehow. Thanks!
