Nope, it was that way when I took it out. I can't imagine anything hit it, she'* running good, so my plugs and valves are intact. I'm thinking it got really hot.

Yep, the A/F gauge has been showing rich for about a month. The sensor failed toward the rich side and the ECM thought it should lean it out. The new one finally arrived from GMPD.

Huh, I've seen them get messed up from mixing in Nitrous-methane but never that bad.
