Mine seemed to be fine after I took the battery off for 3 days then put it back in. The ecu does need to relearn a few things when you do that but I am not sure a weak battery would do that since we have an alternator on the car that keeps power to the car while you are driving. (an alternator is what i was kidding about in that last post btw)
