Q: Rough start up
My car check engine light came on and computer shows code P0455. When I am stopped or parked there is a vibration and when I accerlerate the car jerks and sputter and when I back up the car gives an odd pull back/sputter. And each time I put in gas the car has a rough start up like it wants to give up and occasionally it will say the gas cap is open and it is tightly closed, I even got it replaced. They told me I needed a new vavle cover gasket.
My car has 118000 miles.
My car has an automatic transmission.
