I'll keep that in mind! I reset it again shortly after your reply, and it's been good since through various temps and altitudes. I just have to reset it a few more times per year than others here, it seems.
Also, are these OEM specs for voltages/resistance available to the public somewhere?

I do have an aftermarket charge pipe, but I don't think that is an issue at the moment. A while back, I had my car smoke tested to narrow down a tiny leak in the intake tube that was throwing a code, and the charge pipe was fine. My throttle feels pretty consistent to me. Good tip, though! I've seen many post about charge pipe leaks.
