Hopefully someone can help. have an 05 sedona with 42,000 miles on it and am having a consistent random misfire code on 3,5. I cant really figure out what is going on, it is my wife's car and as you can see we don't drive it much. She says that the light come on after it warms up and the van will idle rough for a second and bam the light will come on, but with the light on (check engine) the van runs fine. It seems to be getting more frequent . I have had it looked at multiple times. The most common answer for a fix is to replace plugs wires and coils, But as you know this is no easy job. Hopefully somebody has another fix. I read somewhere about an update in the CPU but the misfire was at 2100 rpm.
