Engine misfire

My 2012 Boss has started intermittently misfiring between 2000 and 3000 rpm, especially when it is cold. Also am noticing some light noise that sounds like valve train between the same rpm range, but only when it is cold. After the engine warms up, the noise dissapears.
Haven't been back to Frod yet. Anyone having any similar problems, or any ideas that might shed some light on what is happening would be appreciated.
 
I have not but I have noticed mine load-up after running it hard then then turning it off. When I start it back up minutes later it will not run smooth. I've experienced this 3-4 times now.
 
Thanks for the reply. I talked to my salesman today, who is a personal friend also. I'm taking it back on this Friday to let them take a look at it. After I hear from them I'll post what I find out.
The only things I have done to it is that I have removed the baffles in the side pipes & put a Rousch axle back system on it. Otherwise it is as it left the factory.

Did your check engine light come on after the misfires? My problem was a bad wiring harness, but since that has been replaced I haven't had any issues to date.

Are you sure it is a misfire? Has it thrown a code? There seems to be a little "trailer hitching" effect that happens when the engine is cold in that rpm range. The problem becomes more pronounced if the AC is on. Lets us know what the dealer saids.
