The best way to check for a vacuum leak is let it idle and spray carb spray all around looking for the rpms going up or down stumbling or dying. Or better yet a evap smoke machine.

Hutch here Thanks for you answer, but do you know the answer to the first part of my question? What's the best way to get to bank 1 upstream sensor. Thanks!

If there is a heat shield on the exhaust manifold remove it. Then unplug the sensor and use a short o2 sensor socket with a ratchet to unscrew it.
