OBD II never ceases to amaze me. The other day, I went out early in the morning, to do my obligatory early a.m. weekend thrashing of some unsuspecting back road, and the MIL was on. For the last few years it has come on every few months, and I found out that a good 90 mph+ romp for a few miles will make it go out again. Never bothered to pull the code, not that concerned about it. But I did the "blow out", and it was still on. Disappointed, thinking I have some new glitch to chase, I headed home to investigate. On the way, I stopped to get gas. My fuel cap was missing. Some SOB took it in the night, I know, because I had washed the car the night before, and I always wash inside the fuel door (yes, I'm nuts) and the cap was there then. Didn't know it could sense that. Got a new cap, and the light is gone. Amazing.
