Why do you guys insist on messing with O2 sensors to lean fuel ratio?

There is an easier way. It's called the atmospheric or barometric pressure sensor. If you put a 25k pot switch on it you turn it down until the idle speed lowers. There are no funky lights or warnings to contend with. You are simply telling the ecu you are driving at a higher altitude than you really are.

They are usually three wire, ground, 12v, and one thats around 2-5v. The lower voltage one is the one you want to put the switch on.
