   the car is a 1.1 spi black top. Normally starts fine in warmish weather (like in the daytime at the moment). Normally won't start in ice cold weather without fuss. To get it to start when it's playing up you have to add some revs. Also once you have got it started it will stall as you dip the clutch to change gear (battery light also comes on), select a gear and normally it comes back to life. After its warmed up the idle rpm is also normally higher than it should be by 200 odd rpm. Here's a list of thing's I've done, any other suggestions welcome!
   
   Changed plugs
   Checked battery
   changed coolant temp sensor
   changed air temp sensor
   adjusted tappets - helped improve it slightly
   changed stepper motor
   changed fuel filter
   
   Can't put it on a diagnostics as the plug for it in the cabin appears to be dead :s
