Vacuum leak diagnosis for 560SL
Dear All:
I have a rough idle problem with my ’86 560SL and after performing a standard tune-up (new plugs, ignition wires, dist. cap, and rotor) which was of no help, it seems the next thing to investigate is a vacuum leak.
Can anyone guide me to the relevant file on the MB Service Manual CD-ROM, as I can't seem to locate a vacuum diagnostics section? Otherwise (and assume I know little about the vacuum system but do own a Mityvac ), can anyone guide me through the logical steps to test and hopefully track down any vacuum leaks?
Any help is much appreciated.
Thanks,
Ryan Potts
