It could be a few things, but lets start with some basics. Try seafoaming your vehicle. Buy a can of Seafoam. Suck up 1/2 the can into your engine with the engine's vacuum tube, pour the other 1/2 in your gas tank. There are plenty of videos on youtube https://www.youtube.com/watch?v=6OVIfkPpJ4Q . This couldn't hurt but depending on what is your actual problem there needs to be more information provided in time.
