Hi everyone! I’ve been searching on here for a thread related to my issue but haven’t found one with my exact symptoms.

i have a 2017 xc90 t6 momentum. 70k miles. Approx 6 months ago I started to notice a creaking sound when shifting gears and when I would let off the accelerator. Couldn’t figure it so I just let it ride. Fast forward 5 months- check engine light comes on (p0171) and engine starts running rough during acceleration. Cleaned the MAF, and replaced oxygen sensors. Check engine light went away and hasn’t been back since (it’s been approx 3 weeks and 500 miles) but the engine shaking is still there. So I did some digging and found the upper torque rod was shot so I replaced that and it helped but still have the shaking. Idles fine, has plenty of power like normal, no check engine light, just a bad shake at speed/ under load. Anyone have any suggestions?
