Went to a small cruise last night about 100 miles away. Several nice vehicles there. As soon as I left the SSR began to run irradically with almost no power. Check engine light came on and stayed on for 25 miles. Ran like a three-legged dog. Stopped at an intersection and when I resumed speed it cleared up. I noticed that there was a little different exhaust note. BYW I am learning to really love the note of the SSR. Went in to my dealer today and the scan said I have a bad O2 sensor. Nearest one is in Lansing, Mich. (a world away) and will have to wait until next week. Had plannned on a parade (Dogwood Festival and show) tomorrow, but don't know now whether to or not.
