Vladimir,

Thanks for your response. The vehicle was brought into the dealer previously for this problem. At that time, I was told that it was related to the "lawn mower" syndrome. The service representative told me that they replaced those components. However, I think the only thing that was replaced was the plugs. The reason I believe this is that the vehicle does not have the traditional spark plug wires. It has an electrical harness that attaches to each plug through an electronic module that mounts directly above the plug. Looks like an expensive array of equipment to arbitrarily replace especially since I wasn't charged for anything. This is why I believe that if they did replace anything, it would be the least expensive part that is also less time consuming. I think that the service representative might have been a little askew when he told me that all those items were changed free of charge. I am cautiously refraining from saying anything deragatory because I believe their intentions are sincere and so far the service that I have received has been nothing less than superb. I did look at the plugs this weekend and yes, they are very new. The car goes in to the dealer today, I will let you know what they find.
