"Random" Misfire code on brand new E450 with 200 miles
When I picked up my new E450 All-Terrain and drove up the street, immediate a warning light came on telling me to shut off engine asap. I returned to the dealership and got a loaner. Later that day they returned it with a new valve. One week later, the car started shaking, and when I pulled over I noticed the engine warning light. The car was towed. I'm now told they found a "random" misfire code, but they don't know what cylinder or why. I make long drives and am quite concerned about this. Has anyone had a similar experience, and if so, what was the outcome?

I will ask for a detail on the service that occurred on the day I purchased the car. I know that they took the "valve" off another vehicle so that I wouldn't have to wait for the part.
