Hi everybody Had the above vehicle in today, fault coded and came up with p0171 fuel trim too lean. Looked at the air mass sensor and at idle it was 1.65 g/s and at wot in 3rd gear it just reached 40 g/s. Now im thinking that these values are too low but not sure about the g/s. Can anybody give me some advice it would be most appreciated.
