Battery unplug > Car acting different

[Gibbsinator]

I unplugged my battery and started my car and it seemed a little odd. Idling was rough some, and at one point, a check engine light, and low oil light came on. They did go away. Is this natural? I had battery replaced 4 months ago and seemed not as drastic. I checked for fault codes none were there

Yeah, mine sorta did that. Low idle, almost cut out.

most car will do something like this as the ECU starts to readjust/relearn things

I thought so, I kept checking the fault codes and mode 6 to see if anything was different. All pretty much looks the same.

yep learning again is what i would think

Can this learning be turned of without a tune? Mine gets worse as it learns.

Disconnect the battery for 1 minute or more.Reconnect the battery back.
Without turn the engine ,Turn the key to ON position for 1 minute.
Turn Key to off position for 1 minute.
Turn engine on , let it warm up to normal tempeture after that let the engine run at idle for 5 minutes.Turn engine off.
You,re done.
