I am not sure about the Air mass meter being the cause, but I did have some issues with My espace running badly, Renault replaced 3 air mass meters under warranty, and then Renaultbillier on this forum told me it was likely my intercooler weas blocked or damaged in some way. It turned out he was right. New intercooler solved all the poor running issues once the air mass meter could work properly again.
In you case, I would however suspect its an issue with fuel not getting through. Does the vehicle cut out or anything like that when you see the fault and press the acceleerator all the way down?
Hi Colin.
No I have no cut out. As you said it seems to be lack of fuel. Since I disconnected the iar flow meter there has been no problems so hopefully it stays like that :-) (The car runs perfect without the air flow meter and i do not see any change in fuel consumption so I will just continiue like this.
