taclking maintenance today, i replaced the battery in the m5. everything went fine, until i start her up. she sputters and dies. i'm freaking out, man. do it a few more times until it idles rather roughly. i take her out for a drive, she pulls fine to redline, no smoke or drama. whenever i come to a stop she dies. gets better after a while, i put about 20 miles on her and she seems to be running fine now. was this a case of the DME needing to adapt? i'd be surprised everything was just wiped clean like that. checked all my vac lines and such, everything looks fine. weird, that's all.
