? Oxygen sensor signal fluctuations in the signal than the much smaller fluctuations. Also note that when the catalyst for the "off" (or up to operating temperature). Let's us see the oxygen sensor of detection.

? Exhaust oxygen sensor with electronically controlled fuel injection engine idling occurs if the instability in the operation, Accelerating weakness, increased fuel consumption, exhaust and other failures exceeding supply, ignition no other fault, then the most likely route out of the oxygen sensor and related problems.
