Battery died now wont idle on its own
Hello all,So my 02 540 was running great for all the holiday shopping. Parked it 2 days and came back to a dead battery. Trickle charged it over night and it cranks right up but dies if you dont have foot on gas peddle. Even when car is warmed all the way up she still dies. No check engine light on. After a few dies and restarts I now know I need a new battery as it ran dead again. Could the battery be the problem? I searched a bit but did not find an answer. You guys are always great!! Would someone please throw me bone? Thanks for any help anyone has to offer.
