CAN bus data says sensor detects lean fuel mix. When transitioning from cold start to warm fuel mix starves out on all 4 cylinders. While in cruise, car will lose power for a few minutes and cruise control is unable to get power from engine at times. Changed fuel filter, removed and checked/cleaned absolute air pressure sensor, air solenoid, throttle position sensor, cleaned air filter, cleaned vac bypass solenoid, o2 sensor front and back were suposedly replaced, many others have changed fuel pump without fixing it. I replaced fuel filter and was told it still starves out.
Have not pulled and cleaned front or rear o2 sensors they aren't very old.
