It should oscillate by about 10% (e.g. 45-55% ) when the engine is warmed up. If it's at a fixed reading of 50% at operating temperature you may have a bad O2 sensor. An oscillating reading of approx. 70% reading indicates a slightly lean mixture, but still within the acceptable range. Does it oscillate?
