Engine Light due to o2 sensor

[BlakeTillz]

Right my car is decatted, i have the front lambda sensor replaced by a bosch one from euros. All went well no problems. Few days ago i realised the eml on. So i put rs tuner on o2 sensor fault due to decat. I erased and light gone. Then it came back, this time i know why.
It keeps coming on every time i drop down gears to slow down or coming to round abouts etc.. Since that day every drive i go on dropping down gears the light just comes back. Anyone know the reason for this? Its a strange on :/

any help would be brilliant

cheers Blake

sounds like you have your post cat lambda in the decat.. try bunging the hole and cable tie it to the chassis
