The Infiniti arrived at the garage with no check engine light initially, and a noticeable hesitation when accelerating.
During the road test, the check engine light did eventually illuminate and I did feel an intermittent hesitation when accelerating from a stop.
After a brief inspection, it was quickly noted that the air induction boot had separated and was sucking in air. This would make perfect sense, as the computer did store a bank one system lean fault (PO171).
I always like to keep the duck tape around my vehicle just in case something like this happens, you can easily temporarily bandage the area of leaks until you get it to a point of a permanent repair.
