I'm curious if anyone else has any experience with this happening to them. I've seen mixed but no definitive answers on whether it's normal for a 240 to buck and shake at idle for a few minutes after starting it after the battery has been unplugged. From what I understand, the computer has to relearn its settings and adjust itself but I'm wondering how long it takes for it to do that. After it stops shaking, the idle climbs fairly high and stays that way until I shut it off. I can immediately start it again and it idles just fine. Also if I drive while it's seemingly misbehaving, the idle shoots up as soon as I stop and put it in park. On my way home it behaves normally as long as I'm not gone too long. I had this issue in late winter/early spring and replaced some things, namely the intake gasket and the coolant temp sensor among some other routine maintenance. I don't think it really changed much but it didn't give me any problems again until my battery died last week and I had to unplug and recharge it. It died again yesterday after I hadn't driven it for a week. I couldn't find a parasitic draw anywhere so I guess I need a new battery. This one is 8 years old.
Anyway I'm just curious if it's normal to experience erratic idle after disconnecting the battery and how long does it take to relearn idle and go back to normal?
