So do you think I should still look at replacing the O2 sensor since the trims are high? Something seems off still. I have gotten a code a couple times over the past few weeks that puts the engine into limp mode.

2906 - Intake air system: Suspicion of leaks between turbocharger and intake valves.

The weird thing with the code is that each time it occurred was while getting onto the interstate with light acceleration while in 5th or 6th gear. Yesterday I also had one rough start (engine was relatively warm still) where the car almost stalled. These issues seem to occur randomly though which is really throwing me off.
