I Have a 2001 honda accord v6 3.0l EX I I turned on the car this morning and the check engine light was on so I hooked up my ODB scanner and had six codes all misfire codes I then checked to see if I can find out if there was just a single cylinder misfiring by testing each one no change in the motor when disconnected

 

Clear the codes . And see of they return.
A good scan tool should be able to tell you which cylinders misfired

Is it misfiring now?
misfires can be from plugs, coils or even maladjusted valves.
