o2 sensor recycling

[Gravitar]

This is by far one of the longest, most detailed introductions I've ever read. The way the OP describes what he does is just mind numbing. I almost had to read it twice to try and absorb all of the detail he has put in this heart felt introduction. There are actually tears pouring out of my eyes at the way he incorporated "o2 sensor recycling" into this marvelous introduction. Just absolutely beautiful.
