This could be the notorious idle problem with manual E46's. My car's idle used to go up and down while coasting, so I replaced a bunch of parts including Vanos seals, ICV, DISA valve, but in the end, a DME update fixed the problem.

If not, I would go to Oreilly or Autozone and have a battery/alternator test (free).
