Hi. 2013 2.4 120k. New pistons. Cam the fc219 cause a leak or be open and change the long term trim?

The air that affects the fuel trims are measured mostly by the MAF sensor.
Other things like the O2 sensor, coolant temp sensor, ECM, etc can directly change the trims.

The fc219 is an air bleed to the crankcase.
That is a different chamber.
