A bit of background on the 2005 Kia Sedona. Until a year ago was only driven in the summer and only has 33,000 miles. Driven Upstate New York, not too much dust (only one Hailstorm), and has a new front bumper.

The check engine light came on in the Family's 05 Sedona while driving Westward on New Jersey I-80. Owner's Manual says the check engine light has something to do with emissions system. The engine is still under warranty so we kept driving the 180+ miles to home (after listening for abnormalities checking fluids with everything normal) and nothing happened. I have noticed occasionally it smells like gas and BBQ and the gas mileage is crummy (high teens) so my theory is a bad O2 sensor.

What are your opinions?

Looked around and did not see this asked elsewhere.
