Check Engine Light Misfire code
 

I have an 06 H3 and have a question has does anyone get a check engine light and when they scan it get a misfire code. I know they say at idle the engine will decrease in rpm but I get it when going true deep snow and working the truck alittle or when remote started. Sometimes it stays on for a day or two sometimes goes off in a few minutes. I moved the misfired coil pack to a different plug to see if that is the problem and ideas or suggestions would be greatful
