Hello got petrol insignia A20NHT
I receive service your car soon message every other 2 weeks (no regular pattern)
I got a cheap diagnostic scanner and it says P0171 lean fuel B1
The instantaneous fuel consumption at idle plays between 1.3 and 1.5 L/h
Today I loosened the filler cap while engine is running and the instantaneous fuel consumption indicator dropped to 1.0 L/h and steady
One more thing, when I fill the tank the car feels jerky at idle for a few minutes then becomes normal
Kindly advise on what the problem might be
