Drove last night for about and hour and stopped at a friend's house. Was showing him my rsx and lifted the dump bed. On the exhaust at the right side on a braided steel flex line is what I assume to be a oxygen sensor. It was glowing orange. Is this normal? Speed before this was 10-15 mph for about 2-3 miles. Speed before this was 15 miles at 20-25 mph. Was a cool night in the low 50's. Should I freak out?
