So much for selling the coupe. I went to replace the downstream O2 sensor a couple weekends ago but after getting the old sensor out I realized the replacement had the wrong connector. Drove it back to my apartment with no downstream O2 sensor so it was hilariously loud. It's been sitting for maybe a week and a half or two weeks. At 4:30 this morning that same hilariously loud exhaust woke me up as some thief drove it away.
