hey guys my 560sel has a rough idle low take off power and shakes like a hot rod at idle. some people have said i have old and bad injectors if so can i clean them for now? and if so how?

How many miles on your car? Injectors are good for about 200,000 miles. Also check for air and vacuum leaks.

304,o86 says alot right there i bet. so soaking them in biodiesel is a waste of time then right?

As what Mr. jdc1244 said, check for air and vacuum leaks.
And YES, a bad injector can cuase such problem and in my experiance it would never be cleaned successfully.

The injectors start falling off after 100K..@ your mileage I'm quite certain they no longer function as they were designed.

What other service have you done in an effort to solve this issue?
