I rather no one answer then get comments about nothing and have a post full of information no one needs, in that case i would erase the post so its not there wasting space. Next time ask for a better explanation instead of a comment, and your yes is a yes to stop me from posting or you actually know for a fact that it is a fault and know what is? Or should i stick with what i think and consider that to be a fault and 50% is considered to be a problem with the O2 Sensor
