altitude sickness

We have a 73 450sl and just moved from the beach to 5100ft. The car is struggling. I would rather not take it in if I can adjust it myself. is this do-able with basic tools ,if so how.

In theory, the D-Jet system should be able to compensate for the altitude change. To make a long story short: Check and replace any / all vacuum lines, fittings etc related to the engine, MAP line etc.

Then, verify timing, wires, plugs and gap etc.
Then verify the valves are adjusted properly.

Then (and only then), after verifying the injection system, ignition system and mechanicals are all 100% would you (or a mechanic) use a CO meter to analyze the exhaust and adjust the MAP.
