New to mini cooperS not new to cars. Hi all from Arkansas here. Fighting some issues with my 2004 miniS. i ad tis problem a while back where it would bog when you tried to go and it was the map sensor. I replaced both. Then a month or two later my o2 went out so i replaced that. But this thing just doesnt have the power it used to have and sometimes still does that bog thing when you try to go. no check engine lights no nothing. sometimes its worse than other times. Any elp would be greatly appreciated as its my wifes car. TIA

 

Welcome to the forum. Wish I could help you out but I'm new to Mini's myself.
