Hi all, Could someonr please give me some advice where to start, recently I've had a strong petrol smell from cold and goes away when the car warm up . Also the car has a really bad missfire on around 1000rpm. Is this likely to be a coil pack and a labda sencor to cause these issues? I have checked the exhaust for any leaks but is perfect and I have no warning lights on my dash. But this problem does not show up as a fault on a diagnostics unit. Please could you give me some. Advice. Many thanks Jon.
