I started the car and it acted like it was running on five cylinders. I took it to the dealer to have it checked. they said it was not the electronics. So they took the valve cover off to see if they could see anything. Nothing So they took the head off and found a MAC tool called a pick. They said the valve spring was broke. That the pick was in the valve chamber and probably caused the valve spring to break. The motor has never been worked on so the question was how this tool got in the motor. The mechanic said it was probably left in the motor when it was built. So I am contacting Dodge to see if they will compensate me for the cost.
