Fuel pressure shouldn’t affect one bank only. I’d be thinking the vvt or cam solenoid as someone else mentioned, or o2 sensor - except op said fuel trims look okay. Fuel trims checked after warm up I trust - if not, check again warmed up.
The VVTs are oil pressure actuated as I understand it. solenoid opens a valve to let oil pressure adjust cam timing. Oil pressure is also supposed to keep the timing chain tensioners tight. So, while the solenoid is most likely, I’m also wondering if there might be an oil delivery problem on that side of the motor.
