Greets.
As a Preface- I am NOT Advocating this procedure since it is basically contradicting M-B's Manual "Fuel Additives are Neither NEEDED nor Recommended"
The reason "I" am doing this is because TWO of my Trusted MB Lead-Tech's/Master Mechanics (one of which is also on the regional Racing circuit) SWEAR that this is NOT a "Voodoo Chicken"... and one of the Techs states "Their Dealership ROUTINELY does this procedure on ALL Major Services".
Since I was working-up a "rough idle" problem on the W140, I was at the "Clean Throttle Body" part of the Mental Diagnostic Flow-Chart. "I might as well service all my cars while I'm at it.." Because I have read a bunch of times the suggestion to "Clean the Throttle Body"... I have YET to run across any PHOTOS of "How To", so I opted to take some pics.
I also know several folks recommend MAS cleanings periodically, as well, so I cleaned those while I had them out.
The Throttle Body "Flap" is not very accessible to "Open and Close" during the Throttle Body Cleaning Procedure , so I ended up just with the "Standard" Atomized Cleaning, Misting the material into the body neck.
Since it is recommended to do the cleaning with the engine WARM, what I did was disassemble as much as possible with the engine COOL, just to make life easier.
This Procedure will take care of MAS, FUEL INJECTORS, THROTTLE BODY, and FUEL TANK/LINES
