Having problems with your 2003 Volvo S40 ?
I have a 2003 S40 with 108,000 miles on it. I was sitting at a red light the other day and all of a sudden the idleing went way down and the car started to spit and sputter like it was going to stall. I pulled over and sat there for about 5 mins and it did not do it again. but why do you think that happened?
There could be many reasons, the idle air valve got stuck or is going bad, maybe a little got caught in the injector or maybe a sparkplug was acting up, i wouldnt worry unless its a problem,i know you dont want to get stuck out on the road, but this kind of problem is going to be hard to find unless it happens more often, i think it may be a idle air valve ,this would just make car stall at a light or run a little rough but you would be able to restart and go, hope this helps.
