If you did not replace you AOS right away, the oil in your exhaust system may have damaged your O2 sensors. I did replace all of my O2 sensors to correct the same alarm codes.
Isn't a P0107 code for a problem (low signal input) from the barometric pressure sensor?

But the theory I'd go on is you were mucking round in the engine compartment changing the AOS and you bumped some wire. I'd start by snugging up everything you could find. Then clear codes and see. ECUs are expensive...snugging up only if the object isn't your wife.
