Codes
2 Answers
My kia optima has the same problem. The codes mean bad readings from the mass air flow sensor in the air intake. In my car it happened after I filled the gas tank and a tube that runs from the gas tank to the air intake spewed gas on the sensor. There is a valve in this line that is supposed to stop the liquid gas and just let fumes through. That vale failed and caused the sensor to freak out. I had to remove the sensor, clean it, put it back, and only half fill the gas tank from then on.
