Volvo s80 2008 2.5 cold start idle

Post by peyot »

Hello everyone..my s80 is acting strange sometimes.Usually on cold starts car idles ~1500rmp for a 15-20sec then drops off to the 1000 and when warms it goes to 750 or so..
But sometimes from a cold start the car idles at 1200rmp 2-3 seconds and then drops to 1000.
It happened 3 or 4 times during this winter, and temperature here is about 0 till 8 degrees.
Is it normal or I should start to worry?I own this car for about six month and dont know much about its brains :?
Sorry for my english,thanks
