RE: 97 Disco Code P9311??
How is the truck performing? If you are OK with it operation, you could let it go for awhile ,but bottom line the 02 sensors will nned to be replaced soon and with your mileage i would save up and just plan on replacing all 4. Doing all 4 will improve your truck performance and mileage. The 02 sensors are pretty easy to replace while out on your driveway.
