I assume it will do this at idle? Would be good to check for codes in the computer. If none, While it is idling, pull one plug wire off at a time. If there is no change when pulling a wire off, that cylinder is not firing. You could also pull each plug and look at them.
Atach a sparktester and see if that wire is delivering spark. If not pull the wire off at the coil and check for corrosion on the coil terminal. See what cylinders are not firing first and if it is spark related..
