nic's car (corsa) has been stood on my mams drive for about 4 months and tonight we have finally got around to moving it and getting it back on the road. the battery was completely flat and it had no petrol in (maybe about 1 miles worth !) so we had to jump start it, it took a while to start up but once we got it started it stayed started but it misfires loads on idle.. when i take my foot off the accelerator the car JUST stays running and it kind of jumps and cuts out but doesn't completely cut out if you know what i mean my brother said it could be missing a cylinder ?? does anybody have any idea what it could be and if it will cost much to fix ? i'm gunna have to ring breakdown and get them to take me to a garage tomorrow.
