Hello--dealer did this: tune up --changed plugs and pressure cleaned fuel rails to remove carbon. The car is eligible for the free fuel tank and fuel pump and check valve sensor assys. This is due to stalling and rough running and is the X53 issue for this car. This they had to order. They put plug wires on wrong--crossed 7 and 1, the service guy acknowledge the error after I brought it back--later he would admit to nothing except the mech" made a adjustment". Car still stalls and bucks occasionally. The lights for check engine BAS and ESP are off. I will take car back for the fuel tank and associated pump and sensor replacements--after 4th of July. I pray that fixes the car. The dealer has a better diagnostic device--but they still did nothing except plugs and the pressure clean of fuel rail and throttle body --at $467 and change. I truly pray the fuel tank and assy fixes all the problems so I can sell the car, and buy a new vehicle.
