O2 sensor? Multiple error codes
 

99 V70, non-turbo, M/T with 145k on the odometer.

Check engine light came on for the first time. Accompanied by hesitation/stutter when I get into the gas, especially at low RPM (below 2000) - otherwise driveable.

Pulled the following codes: P0136 (Bank 1 Sensor 2), P0130 (Bank 1 Sensor 1), and P0455 (Evaporative Emission Control System Leak Detected (gross leak) ).

Before I shell out $400+ for two O2 sensors, does someone have some basic troubleshooting guidance to rule out other possibilities?
