I posted this earlier in new members fourm instead of here. Rookie mistake.

We are really enjoying our Mini. Havenít had it long but what an awesome car. I do have a newbie question and this may not be the right forum but here goes. I had a code recently (301e) I think. Cyl 1 miss fire. Changed all coil packs and plugs. Runs great again but CEL still on. Parts house wonít clear it. If I disconnect the batt for an hr will that do it or will there be unintended consequences for doing it? Thanks!
