Hi all, Have an 07 mini Cooper base model throwing simple 02 code. (2A7F). Have been going nuts trying to figure it out. Checked all the wiring, no exhaust leaks, no intake leaks, replaced the sensor twice (NTK) and Reset adaptations. Code will not go away. Car can idol without throwing a code but as soon as we run up past 2500 rpm it throws again. Hoping someone might have some insight
