2018 Yukon 5.3 with 101k miles. Just had the check engine light and the StabiliTrak light come on. Started to idle rough. Codes P0206 (Injector Circuit / Open - Cylinder 6) and code P0306Cylinder 6 Misfire Detected. It was very sudden. Didn't even notice the light was on till I got home from a quick trip to the store. Thoughts?

Can you swap injectors between 4 and 6 and see if the problem moves with it. If it does it’s likely a bad injector.

What was the outcome of this? I've encountered the same issue with my '17 Yukon 77k miles

If you/re getting those same codes i would suspect faulty injector in the cylinder its saying. not uncommon with the direct injection stuff. can be pretty easy swap with the right tools and some time
