Hi, i have opel zafira 06 1.9 cdti, i connected diagnostic and while i'm driving at constant speed my mass air flow suddenly goes down for fraction of second, like its around 150-160 and then 50-60 and its fizzling at that point then back to 150, and when accelerating and releasing throttle it fizzles.
