Just brough the missus a car. On startup it revs really low. I have noticed that the throttle cable is slack. Apart from this is there anything else which may cause this to happen. Sorry for such a dumb sounding question but I guess that's what scoobynet is for!
It's a 1999 Daewoo Matiz (don't hate me please )

 

Its the wild cam they fit to those crazy Daewoo's.

A service would be my first port of call.

 

If its a 3 pot it will be lumpy.....I'll pay you £1 to torch it
