Yep, I dunno but I _strongly_ suspect the 'retraining'.
BTW, now that I know that those two vacuum lines (which run parallel to each other on the top of the intake manifold on the v6) are 'very sensitive' to being 'in and secured' I make it a point - when, e.g. I'm refilling windscreen washer fluid - to 'check them'. Couldn't hoit!
