This is kind of a "matter of opinion" here. If you're used to today's "perfect idle" cars, this will forever bother you. A very long explanation short - due to the lambda system and its properties - this is pretty much normal behavior for the car. The lambda system is a contant "on/off swtich" - adding and taking away fuel, making the car lean to rich voer and over. Manual cars seem to runs this circuit a bit more smoothly than autos as I ahve seen both with the lambda system hooked up, and it seems auto cars like to "sputter" just a bit more than manuals. Anyways, my opinion is that's perfectly nromal. Others will say it isn't, but from my limited experience, this appears ot be the normal operating procedure of the lambda system. Drive your car, enjoy it.
