No brakes in the morning. It will definitely wake you up more than coffee.

Id have to go look.

After reading over the thread I'd actually wager a check valve getting stuck after sitting because I cant see a leak causing intermittent problems, How long should it take to form a vacuum to spec on start?

What really makes this a difficult problem is because it isn't always there, It would be a long arduous process because you wont know what you did if that fixes the issue. This is the reason why I never bothered diagnosing until it got worse to where I could repeat problem but unfortunately It hasn't in the past 2 years
