were trying to find out whats wrong with his truck it has trouble gaining rpms http://video.cardomain.com/Clip.aspx...8626FC31A6F6F4 hes on dodge talk and having trouble im just curoius to whats wrong

 

I had some issues with my truck a few years back where I would have to fight my truck to get it above about 2500 RPM's. What my issues ended up being was a plugged up cat. I would start with that and check it.

I took mine to a shop and they determined it was bad, but I think you can just bang on the cat and listen for any rattle to determine if it is bad or not.

 

+1 for checking the cat.

If it doesn't rattle, it doesn't necessarily mean the cat is good either.

Get it tested by a shop.
