Hello,

This sounds like it could be a problem with your vehicle's fuel filter. Your vehicle pumps fuel through a filter on the way to the engine, and this filter gets plugged with contaminants over time. When this happens your vehicle's engine will tun rough until it reaches higher RPM's when it will smooth out.
I have included a link down below for you to go to:

Please go through this guide and get back to us with what you find out.
