Can you help me please? My Astra is giving me problems with, when I start the car it starts up and sounds as if firing on 3 pots, then runs rough, after about 3 miles it drives perfect with no missing or sluggishness at all. There are no lights showing on the dashboard, there is a smell of petrol when it runs rough, on tick over. I have changed the plugs, no help- could the leads be giving me this problem, however they are all firing on the spark plug side.
Today the car wouldn't start at all! This is a first. Then after a while I managed to get it started but to me it seemed as if the engine was flooding.
