I have a Peugeot 307 XSi 2.0 on a 51 plate, and following a little crisis at home, left the keys in it and flattened the battery. Jump started it off the neighbours car and went to work. The car kept stalling in between gear changes, but the battery was charging. Charged the battery that day, put it on, it starts okay, but wont idle until its been run for a while and up to operating temperature. Even then, its now quite as good as it was, seems to want to lose idle revs (if that makes sense).

Someone told me you shouldnt jump start modern cars, and that Pugs are bad for frying the ECU if you do - but as she runs/drives/pulls okay, I'm hoping its a simple issue I can fix myself.
