Hi there. From the description you have provided, concerning your vehicle’s Check Engine Light and two misfires, it is advisable that you get a second opinion. A timing chain problem would cause your vehicle to have a consistent drivability issue. Not knowing what code is being stored, it is difficult to determine what direction you should go for repairs. I recommend having a certified mechanic, such as one from YourMechanic, determine why your Check Engine Light is on and why the car is misfiring.
