Try reseting the car....

Go out put your keys in the ignition turn to on setting with out starting car.
Put the gas pedal to the floor count to 5 turn the key off leaving the keys in the ignition then take your foot off the gas and then leave the car alone for at least two minutes...go get the mail or something then come back and start the car and drive it and see if that changes it....I do this after my wife drives the car for a week.
