that means the computer is giving bank1 (the side of the engine with cylinder #1) as much fuel as it can, and the o2 sensors are still reading lean.

it's most likely a vacuum leak, I'd suggest tracing and checking the ends of every vacuum hose, then a smoke test or spray carb cleaner around all of them, and all of the gasket areas between the TB and the heads.

Yup, most likely a vacuum leak...
