Check Engine Light On, Engine Runs OK on Kia Spectra

The Check Engine Light may erroneously illuminate, signifying a fault with the front oxygen sensor when no fault exists. Replacing the electrical connections at the oxygen sensor with a repair kit available from Kia will commonly fix this problem.

My check engine light goes on and off all of the time. It as well was tested to be the Oxygen Sensor. I've had the issue before and Kia replace some emissions valve in the gas tank stating I had over fueled my vehicle and flooded it. Unfortunately for them, I have never over fueled my car in my 10 years as the only owner of the vehicle. I'm rely surprised this car has only had 2 recalls with all of the issues I have had with it.
