Bank 1 is drivers side, but the problem is, since the exhaust comes down to only one air/fuel ratio sensor, it can't really determine which is which. It can only tell you that it's reading lean. "Bank one" is just how the computer's set up to display codes, but that doesn't mean that it's only the left bank. It's possible there's a vacuum leak, or lack of fuel (sticky injector?) It's also possible that the AFR sensor has simply gone bad...

The leak trick is usually pretty easy: Start the car, and spray carb or brake cleaner around the intake manifold and such. If the idle jumps up, there's your leak.
