2009 Ford Flex SEL 3.5 will not idle

After driving the car for a bit, it will stall only when stopping. Vehicle idles in Park and Neutral. I can restart the vehicle and drive it normal but im not able to release my foot off the gas entirely or it stalls. Funny that it stalls only sometimes tho.

New battery, new O2 sensor B1S1 (3 month old code) New Cam Position Sensor (code from years ago but fixed it anyway), new MAF, new Throttle body (electronic and gas the TPS and IACV integrated)

Any hints would be beautiful. I got compression, spark, air, and fuel (idk the fuel pressure but it sure looked pressurized coming out of the injector lol)

Thinking weak fuel pump, EGR, or a purge valve choking the engine. I dont know much about the Ford Modular v6 platform. Im used the the older 4.0 colognes.
