hi i have a s reg 1.6 automatic astra,basically the main problem is my astra keeps stalling when i slow down for traffic lights or such like.on a 20 min round trip it done it 3 times and now does it if im only driving for not even 10 mins..the engine management light is on but goes out if you do above 50 i was told that the brakes were replaced but not with the sensor type and thats why light is on.seems it stalls when temp gauge gets to quarter way point which it seems to reach very quickly lately ..also the oil light flickers when im breaking but both the water and oil are fine any help would be great currently waiting for my brother to get round to doing a diagnostics check but its a long wait
