I have to believe the Air Filter change was the culprit.
I have a 2014 Pathfinder SL with 38K miles. I just washed the car over the weekend and decided to check my airfilter. It was dirty so I hosed it off and let it airdry. Later that evening, I put it back in and drove. The engine turned off after driving a block and the engine light, ABS light went on. So right away, I knew that the filter was the cause.
So later I bought a new K&N filter and installed. The jerky motion went away. However, when I do a sharp turn, I still get a small jerking from the transmission or engine. It doesn't feel right.
Nissan tells me that will go away. Anyone has any ideas?
