i have an 04 cobra with flowmaster exhaust from manifold back and was noticing over time sounded like an exhaust leak, then my check engine light came on and took it too get a scan and said 02 sensor was reading lean so o crawled under car and my o2 sensor was rusting where the ac drips on the car right on to the o2 sensor. has this happened to anybody else and what do you do because it looks like it drips out of the firewall on the passenger side and is very hard to get to.
