What should I think after a chief Mercedes mechanic at dealer says I need to probably have my engine cleaned without a guarantee that this will stop the vibrations from continuing to occur in cylinders 3 and 6 of my V-6 engine? (Cost to clean will be $150, and takes 2-3 days)

I and the mechanic know that it's cylinders 3 and 6 since we had my engine hooked up to the computer. Everytime I shift into "P" and "N," I don't feel the vibrations onto my steering wheel. But in "R" and "D" the vibration is really bad when the car is stationary. As soon as the car's engine revs up past 1000 rpm's the vibrations disappear and everything is smooth. The mechanic did ask me if I high rev my engine a lot during heavy acceleration and I replied yes.

Does anyone know what the solution is to this problem and how this vibration problem started that I could feel on my steering wheel?

Your Answers and insight are appreciated....

you should make this a post in the techincal forum (if you didn't already). I think you would get better responses there.
