Jump Start Car = Major Problems ?
My car battery was weak recently and I had jump started my 1999 SLK230 several times. I thought I had fixed the problem by charging the battery , but it died again, and this time when I jumped it, the idle kept surging between 1000-1300 rpms and there was no response from the throttle. I have searched the archives and have already tried disconnecting the battery. I have also used an OBDII scanner to pull codes and didn't get any. The BAS and ASR lights are both on. I am at a loss to what may be causing this problem, but am afraid to bring it in to the dealer because I know they will just start replacing parts. Has anyone experienced this in there cars or knows of the cause and more importantly, the fix?
