Hopefully it's just because it's been sitting doing nothing for the past 6 months and I'll be able to get it working properly so I can sell it on eBay.
All I have to say is, thank the many gods for my lovely Lexusoh, and never buy a Mercedes!!!
The gas is probably varnished, car's don't run very well when the fuel system is dirty.
Change the fuel filter and get some fresh gas and run it for half an hour. Drain the tank of all the old gas if you can.
If it still does this, make sure the MAF (Mass air flow sensor) is good. A good way to check is by removing its connector while the car is running. If the idle doesn't change, you've found your culprit.
BTW, lots of cars have batteries in the back, it's a good way to have better weight distribution and eliminate clutter in the engine bay. My battery's in the back, but I can jump start the car from the front as well, using the fusebox as a positive and the chassis as a ground (or earth, as you UKers call it)
