Got to check the O2 sensors on my car as engine management light is on again and the fault code is coming up suggesting o2 sensor. Also my fuel economy is dreadful, was averaging 22.5 mpg witht he last £20 i put in and thats being careful!
I know one is above the catalytic converter? but in the haynes it says there are 2 , one above the cat and one nearer the engine. I cant see it tho? Any ideas where it is??
I have a feeling its the one above the cat as the exhaust was changed for a straight through pipe recently and i think it might have come dislodged.
