Should the o2 sensor heat up when the key is in the on position
have the same problem?

These are heated O2 sensors, if they are faulty the ECU will go to a full rich reading, this well may be your problem.

Which o2 sensor? The car has two. The front one is considered to be a a/f sensor but looks just like a o2 sensor. The other is after the turbo. Also the bov starts flowing air when I plug the vacuum line in
