uneven power at low rpm:s --> car shakes a bit

My car sort of shakes at low rpm:s. I have to be real precise with the gaspedal to keep this to a minimum. I'm sure I'm not doing anything wrong driving-wise(sharp driver ), and I don't belive it's supposed to be this difficult to keep the ride smooth. It doesn't always do this but often enough to be irritating.
I don't really have any idéa of what this could be... there's some blueish smelly smoke at startup, that's all I can think of.

...any help???

As ede asked, is it throwing any codes? and whens the last time it had a full tune up?

Bluish smoke is an indication that you are burning oil. If it is only at startup, id suspect the valve seals have gone bad (common problem).

Throwing codes = is the check engine light on?

Tune up = when's the last time you replaced the spark plugs, wires, and cap and rotor?

I was afraid it might be the valve seals and I read somewhere that if some(?) seals go you might get powerloss, so that's why I suspected that.
No it's not throwing any codes. The plugs have recently been replaced, but I just got the car so I'm not sure about the rest.
...Probably should take it for a tuneup.

thanx

trouble shooting is a systematic logical search to finding a problem. for example no start condition logical thing would be to check for spark.
tune up is the replacing of parts, like plugs and wires, as well as adjustments, like timing.
codes are the stored trouble coeds in the ecm. you can do a search here and find out how to do it and pics, alos there should be some info on the main page.

I would check your engine mounts and transmission mount. That could cause some shaking if they're not in good shape.
