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.

Do you
have the same problem?

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

99 isn't real high. Have you checked the other cylinders?

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?
