Depends how rough - I've read that running rough on your model is somewhat normal. Use the search bar if no- one wants to chime in on this one..

Use the in this forum first by clicking engines right above and the go to the right of the page and use "search this forum" from the menus..

Then you can also try here -

That's the forum for your model - more specifically..

Good Luck and Welcome
