Outer Limits 4x4 Board

Hallo,
i am having an issue with the O2 light in my Feroza F300:
when i am running at 4500 rpm the light came on, as soon i reduce the speed the light came off.
I changed the sensor 8 monthsa ago and now it has 15.000 Km.
Additional info:
K&N air filter and Black-box
Lukey extractor
Any tips ?
Thanks
Achille

Have you run through the oxy sensor checkout procedure to see if your earth is OK? There's a link in the FAQ. Did the replacement sensor have the proper sealed plug- if not check you haven't got corrosion problems in the plug.

Possibly try resetting the ECU by disconnecting the battery and see if that makes any difference too.

hey dont know if this helps but was told on usa rocky after light comes on the first time u take the light out dont know much about them but thats what i was told!
