Coincidence or Fix??

Well the other day I noticed while I was working on the a/c that the outdoor temp sensor was stuck on 40*f ... Checked connections all were fine.. Decided to disconnect battery and see if it resets...and it did... But something else I noticed.. The car no longer stalls out on the first light up like it use to... And the idle seems a bit higher at 675 in park...

So my question is could disconnecting the battery have fixed these gremlins.. I have always cleared previous codes using my Mac taskmaster.. This is the first time I actually disconnected the battery..

Thoughts opinions?

What does disconnecting the battery reset?? (other than clearing codes)

I would drive it and see what happens with a some miles on it.
