Which Sourcelet or Guide Best for '80 300SD 116 Vacuum Troubles
The vehicle is a 1980 300SD, 116 Chassis with nearing 300K miles. My problems began with a slight delay in the engine shutting off with the key, and has progressed to no door locks and I have to raise the hood and manually shut the engine off. I have also noticed the engine is running rough at idle, but smooths out at about 1000RPM. I intend to troubleshoot the vacuum system, but can't tell from the descriptions which of the guides I should purchase: the vacuum door lock one, the my engine doesn't shut off one, or the larger, apparently more comprehensive diesel survivor's guide.

1980 300SD Cylinder misfiring while idling
The more I drive this old mercedes the better I like it. Recently I had new motor mounts installed and asked the mechanic that did the work about the engine still rocking and rolling in the engine compartment. He said that one of the cylinders was missing a hit while idling. When it's rev'd just a little it does just fine and on the freeways/hiways it just absolutely purrs. Could it be a glow plug or compression? Any hints would be appreciated.
