The speedometer bouncing is from your speedometer cable....and there is a fuel adjuster inside of the engine bay. I am sure if you do a search you can find some answers.

That sounds very bad. I don't think that's an adjustment issue if it is popping. Where is the sound coming from?

Sounds like a misfire. Run a compression test and make sure you didn't burn a valve.

Take off your air filter and you should see the idle control sticking out next to the air intake. Mercedes make a tool to adjust it but you could see what you can do to without it?
