Its an 03 daewoo kalos, which i since heard arn,t popular, Its 1.4 and its been reving up since i got it may 07. I kept bringing it back and they put it up on the computer and nothing showed, but eventually they heard it themselves and took it in may of this year, just before the warranty was up. it stopped for about a week, and has been doing it since, i didnt know if to go back to them again , its been 4 months now, i think i left it too long now. And i dont know much about cars but theres no rev clock to tell what rev its at when starting.
