Getting bad fuel economy so im gonna get my injectors cleaned, but then i read that a black exhaust tip means that its running rich, so maybe it's the O2 sensor thats at fault? (even though it doesnt report any faults with a diagnostics check)

Check the pics...




That would be considered running rich?
