Another thing. My (former) mechanic did the same thing you did.

He pulled all sorts of vacum hoses off and on and nothing changed, so he determined that there wasn't a vacum leak because nothing changed.

But, there was a vacum leak all along at the intake manifold seal. Which is why nothing happened when he pulled the vacum lines off.
