I have a 00 s40 with a rough idle, I have checked the codes and here is what came up
1. 650 malfuncion indicator lamp
2. 300 random misfire
3. 301 cylinder 1 misfire
4. 14 cam position timing over advance or system performance
5. mass air volume
6. 02 sensor bank 1


I know this seems like a lot of codes. Wich ones could effect the rough idle.
The engine smooths out when reved above 1500 rpm's or when I get going above 15 mph. I have checked to see if I am getting spark from the coils at the plugs and I am. Also do you think the flame trap needing cleaned out could cause a rough idle. Any advice would be appreciated.
Thanks
Dennis
