Hey the everybody I have mk1 seat arosa on an r plate and well as u probly guessed I have a bit of a problem wif the car. Wen I'm out drivin it I have noticed that wen I stop at a junction or traffic lights the car seems to suddenly drop revs on idle and the shoot back up again. For example if I'm sitting at the lights and the car is idling at 900rpm suddenly it will drop right down to about 500rpm then str8 away shoot back up to about 1100rpm and then settle back down to 900rpm. This is not just once it is everytime I'm at a stand still and it happens 5 or 6 times each time and also gets more vigorous if I have cd player or lights on I someone would be able to shed some light on the problem it would be much appreciated thanx Aaron
