If you already made sure B1S1 O2 sensor and MAF sensor are both ok, then air leakage between MAF and intake manifold is a big suspect, check fuel trim using live data scanner to see if the engine is running too lean or too rich caused by air leakage. Do this after engine is fully warmed up so the close loop control is running.
