97 Disco I Question

[taskforce121]

Thought I would run this question by the forum to find out what ya'll think. Everytime I fill up the 97 Disco with gas, within about 30 minutes, I throw an 1177 code (Maximum Negative FMFR Correction Fault). I clear the code, and then it repeats the next time I fill up. Any thoughts on this?? thanks
