GWAHAHAA

Hi i was given my lupo by my dad. I have the same problems driver door does not lock from the outside, the driver side window motor actually set the car on fire when my cousin had the car (not pretty) the passenger side window did not work when i got it. A few months later my friend pressed the button and the window went down then up mabey for an hour and now just clicks again. My rear window jet has always just sprayed in to the boot. The car used to cut out when pulling up or clutching so i cleaned the throttle body and that done the trick also new triple spark plugs helped. 4 months on and the car seams a little down on power i look after the engine with regular basic services as it has done 113000 miles this is a 1.4 75bhp. I would appreciate any ideas on why it could be down on power thank you
