vauxhall zafira 16 16v 2003 fuel problem?
My car is using loads of fuel. The fuel trim on my scanner shows +15% ltft and the stft shows + - zero so the o2 sensor has reset the baseline so would suggest a bad air leak. No air leaks. car runs fine just loads of petrol. Any ideas please. Forgot to mention lambda code present.
