Well I have had a few trips to my mechanic on this vehicle. They are still baffled w/ not being able to pin point a misfiring that keeps the vehicle bogging then lunging! It has been taken apart 4 times now and replaced oxygen flow sensor, 02's and other stuff and still can't keep the check engine light off or find the problem. It is horrible on gas mileage!! Obviously this year needed a recall... and I have had nothing but problems since I purchased from a private party 4 months ago.
