Oh, and I read an interesting take on why people think an engine running lean is hotter.

A perfectly tuned engine usually runs richer than stoichiometric. So if you lean out from there it gets hotter till it hits stoich, then cooler after that.

So an engine running leaner than a slightly rich tune gets hotter but leaner than stoichiometric gets colder.

Does what I read make sense?
