Hello this is Fran=E7oise, Luc's wife.

Could it be something that obstructed the airflow to the airbox in an
intermittent manner ?  Such as a leaf flapping ?

I assume that now, as all spouses, I do get a 2nd chance...  I will use it
soon...

Regards from Montreal,

Fran=E7oise, Luc and little Iris...
