2005 Dodge Neon timing belt

Hello. My car reciently has been running ruff when i'm stopped. Was told to check the timing belt. When I called a local repair shop I was told the my car didn't have a timing belt but that ot was electric timing. When I looked up replacement parts there was one for it. So i'm confussed. I would really apreiate you advice on what to do. If it is all possible would like to do myself to save a little money. Thank you for your time. Melissa
