Its a 2011 dodge durango crew awd 3.6. I have changed all plugs 3 times already, didn,t make a differance so i changed all coils and replaced the battery. Still get the check engone light comes on at idle, thats the only time it comes on. Sometimes after reseting the light it will take 3-7 days before coming back on. It seems the times it has comre on is after running into store and coming back and restarting. I have checked all injectors the all read about the same ohms.

 

If I'm not mistaken, bank 1 on this engine consists of cylinders 1, 3, and 5, so your misfire codes are basically all of bank 1. Just before the check engine lights comes on does the engine run roughly? Since you don't mention it, I'm guessing not, especially since it typically pops up the CEL at idle. Do you have the list of specific codes that are present? If the engine doesn't run really roughly, I'm guessing the issue is more something like a bank 1 knock sensor or some other sensor common and specific to just bank 1.
