What's the compression????
The Ignition timing doesn't change by itself, it's either 10's of thousands of kilometers of wear for a very minor change or someone F'd with it.
It will not change enough by itself to cause a rough idle in a short period of time, it takes years, not days weeks or months.
You've got some other problem.

look at bean banit´s link!

If that fails I´d have a look at compression.
