Vibrating between 1500 and 2k rpm

I just bought a used 99 f250, 7.3. The shady guy I bought it from said it misfired when he bought it. He brought it to his mech and got 2 of the injectors changed. Then he said it started doing it again and he brought it back only to find out that the # 8 cylinder is misfiring. I figured I would try and replace the valve cover gaskets and wiring harnesses first. Any way to test the injectors before I put the top end back together. I heard about some buzz test???

yeah if you are going to work on these things very much then I would strongly suggest in investing AE you will be able to perform a buzz test cylinder contribution test monitor your ICP and IPR as well as slew of other things
