CL600 misfires

Good morning, I have a 2004 CL600, the car went through the car wash and after a brief stop at the store, it was misfiring badly. After a short time, it was running well enough to make the 2 mile trip home. After another two hours, it was running fine.

It did the same thing 2 weeks ago when my brother tried to test drive it, and they took it to a mechanic who said the culprit was wet coils from washing. I'm not so sure of this diagnosis, what do you guys think? I'm irritated because I bought it because I though they had taken care of the problem! It's a large dealer, not one of those corner joints.

The coils are a known weakspot.

Some go out at 10k miles. I think mine bit the dust around 70k miles. The old ones are just bad.

Need to be very careful with car washes on these cars
Hand wash /low water wash only
