Hi, i have a 2002 307 1.6 petrol, the antipollution warning came on about 5 months ago, also the eml is on. The car has not run any different at all, still starts and drives o.k, light was put out, o.k for another 6 weeks, then car used on a run and light came back on, checked error code again, Replaced oxygen sensor after catalyst. Put light out, o.k again driving about town, then today took on a longer run and the light came on again with the same warning. Any ideas what it could be? The oxygen sensor before the catalyst was replaced when the fuel contamination happened( supermarket fuels back last Febuary)

Any help would be grateful
