for some reason all of a sudden the s3 has decided to start playing up again. its nots a major problem but for some reason when im driving it reasonably hard, by this i mean changing gear 4000 rpm plus, its starting revving up as i change gear. So by this i mean soon as i let off the gas and put the clutch in, the engine will rev itself up another 1000 or so rpm, its making it sound like i cant drive. Does anyone know what this could be??
