Per the WIS, it looks like O2 sensor #1 is in preheat mode too long. After it times out, preheaters on both O2 sensors are turned off and you stay in "open loop" mode (worse mileage and worse emissions than in "closed loop). The preheater is not much more than a coil of wire (like a light bulb element) that heats the sensor while the cat/conv is getting up to temperature. A big pot hole could cause the coil to fail.
Sensor #1 is the O2 sensor closest to the turbo. That would be the first suspect unless you know what to probe for, using a multimeter to probe the wiring harness ... Ron
