i cleaned the egr valve and i also switched number 2 injector with number 3 but the check engine still said number 2 had misfire so what could be the problem now? maybe the valve?i've put everything on this truck new and it runs good for a couple days then the check engine light comes on and tells me that number 2 is misfiring and the truck shakes a little.

Have you checked the condition of the plug? Coils? Have you checked to see if the compression is good in that cylinder?

I understand, but all cylinders need to be within 10% of each other. If the others are 140+ it could cause a misfire. I know it sounds crazy. It's just a suggestion.

Also, have you checked to make sure the injector for that cylinder is getting power?
