[Por_sha911]

This is a M Benz question but the wife's `85 380SL uses the same CIS system as in the 911:
The car hadn't been driven for 2 weeks and the battery was dead. Someone tried to jump start it but put the jumper cables on backwards (musta been some sparks!). When they turned the key and got nothing, they reversed the cables but the car barely ran. I found out all that went on and thought maybe it was just loaded up and needed to be blown out. I took it down the road. At first I could barely keep it running in gear. After a few miles running in 3rd (it has overdrive) it will idle fine but has zero power and it bogs down if I just try to accelerate normally. I have to coax it to get going by running up the idle a little and then slapping it in gear (not good for the Automatic trans I know). So what do you think? Do we have an electrical problem? I thought I would pull the plugs and see what they look like. Any suggestions? I have tried to get help from a MB BBS in the past but they seem more interested in chrome wheels and new CD changers. (Porsche content: I need to stop wasting time fixing the Benz so I can drive my 911!)
