After getting my starter changed on my car. I took my battery off and left it sitting around over night, I was thinking of changing it before i decided not to bother with it. After I put my battery in, my car's settings were reset, the check engine light and everything dissapeared. Its been a couple of days and I've driven my car everywhere, and this problem has not come back. I wonder if it was my starter that was staying engaged and causing this problem before dying? or did removing the battery simply reset the car and rid it self of this problem?

Before anyone else disconnects the battery to reset you're car, make sure you have you're radio code ready....but car drives great.
