Irregular idle when cold

[micha3l1985]

My car has developed a weird idle thing Three days. When I start the car in the morning the idle fluctuates up and down about 200rpm for about 30 seconds straight after startup. I know this isn't really a big deal but the car only has 2000kms on the clock and I wouldn't expect this from a new car. Has anyone else experienced this. I have contacted Mitsubishi and they want to keep it over night but I would like to leave this as a last resort as it is hard for me to organise due to work.

I have had it on occasion and I've put it down to a poor tank of fuel or the self injector relearn which tends to happen in the morning. The injector relearn whilst driving feels like mild surging and slight changes in engine noise/rattle which lasts around 1min or so.

sure it's not the airconditioning cutting in and out (as 200rpm is about what our car fluctuates with A/C).
try starting it with the airconditioning turned off
