Wondering if there is ..... and ...... if i have to do an idle learn procedure or will ECM relearn after driving the car a bit more... I have a high idle and high revs on startup after battery died and left E52 ECM Memory reset code.

Which car ?
There is a procedure, but it's not necessary. It'll learn quickly on its own.

Can't remember it exactly ATM. I want to say run it for a set amount of time in idle with all accessories off, but I'm just not sure.
I have never yet had to do an idle learn.
I`ll just take her out for a long drive today and see what happens.... Good enough weather expected today. Thx though.
I found this online, Seems to be inline with what you were suggesting MC . If i dont get a chance to get out for a long ride today, I `ll try it

The TP sensor/IDLE LEARN should be preformed when-

TP is replaced

throttle body replaced

PCM replaced

battery disconnected or replaced

PCM code 52

IAC adjusted

TP sensor adjustment has been preformed
