Took my car in to check on a stall problem. Turned out to be a failure in my junction box. It was a friends mechanic who was a BMW certified mechanic trying to make some extra side cash.
We ended up getting into a minor argument and upon leaving the shop I had my cel on. Diagnosed it and it was my front bank 2 o2 sensor.
Is there something he could have done? Perhaps disconnected?
Could you guys point me in the right direction before I replace the sensor.

Thanks,
