Hey,

I've been struggling with a vacuum leak on my new-to-me MY03 3.2S

Attached are a couple of Durametric files from an earlier datalog (idle only). The obscured top line is FRA (bank 1)

My guess is the car is runninging lean (adding fuel) but other than a smoke test, I don't know where to look.

Does anything stand out in the attached charts to anyone?

Thanks
