Usually this code is the result of a bad bank 1 HEGO.

It usually means what antony25 suggested above.

Kinda hard to have any other ideas . . . try switching the HEGOs and see if the problem moves.

It may also be due to a dirty/bad MAF.

Had the CEL come on on our 98 Contour with a P1131 code. Found the clips that hold the lid to the air cleaner not snapped shut tight - hence extra air. My scanner indicated that the O2 sensor output is within range so hope that this was the only problem.
