Battery Replaced

[Jeph]

I just replaced my battery with a Duralast. My last battery was a Porsche OEM. After installing it, it seems my car's rpms bounce between 500 & 550 at idle (about one time per second). Car starts better now, that's for sure!

Ideas?

Your car does not know if 12 volts come from a Duralast or Moll battery.

You need to drive it a bit so the DME can readapt, because you disconnected the power souce.

ditto that!
