I assume that it is doing this cold and warm. First try checking the coolant level for the radiator or cooling system. It needs to be full and it needs to have any air in the system bled out.
If that does not do it, check for vacuum leaks like a broken hose, gasket leak at say the intake manifold or the EGR valve could be have an issue.
