Jerking on Acceleration

[FloridaWillys]

I currently own a 2020 Willys 2.0 T with 30k experiencing jerking on acceleration. As the single owner of this vehicle I installed a S&B cold air intake in October of 2021 and BOV under the hood. Since symptoms started I’ve purchased an OBDII that produced the code P0506. While looking for the root cause I’ve ensured the intake is sealed with no cracks, used compressed air to clean the dry filter and inspected the MAP sensor. Initially I thought it may have been a throttle body issue but have yet to clean (seems premature). The MAP sensor doesn’t snap into the intake tube but fits snug looking as though it just left the dealership. A cable from the EVAP system was unclicked (no idea how) but has since been secured and wiped of oily residue with a paper towel. I have also hand tightened the bolt of the EVAP to the tubing (seemed unusually loose). I’d like to avoid the dealership due to unruly wait time and an unnecessary cleaning of the IAC. Although the filter itself seems relatively clean and free of debris, I did purchase a replacement. Any and all advice on this frustrating matter is welcome.
Thank you!

In no particular order:

-While a bit labor-intensive, one well-regarded M.O. is replace aftermarket fitments with their OEM originals. This can sometimes isolate a problem-causing part, or parts. You could choose to remove the cold air intake and the blow-off valve concurrently, or one at a time, and then test drive the vehicle to see if the acceleration issue remains.

-Consider using a new OEM (Mopar) air filter when reinstalling the stock air intake plumbing. Just a thought.

-Is the warm idle speed lower than it should be, as the code P0506 suggests?

-The 2.0T uses direct injection, meaning there is no throttle body.

Thank you for the info! The new filter has been placed from S&B and will continue to monitor. Idle speed has not varied from around 800 rpm and remains constant.
