Oxygen Sensor
Though I am not sure this is the oxygen sensor again yet... I am wondering what possible problems (if only a few..) could cause an oxygen sensor to go bringing on the check engine light. I just had the sensor replaced not long ago and already the check engine light is on again.... might be the same problem... might not be... I will find out tomorrow. If anyone can help me out it would be appriciated.
