It means that cylinder is not running as strongly as the others.
How to correct it?
That usually requires some mechanical knowledge and equipment.
Causes could be
spark plug
ht lead
coil
injector
riding valve
burnt valve
holed piston
bad inj driver
Bad contact or broken wire to coil or injector
broken valve spring
seized valve
Starting to get the idea?

Can you post a screen picture of the test results...
.. piston rings, damaged bore, blown head gasket etc..
If its shocking you can fix it with a 402 stroker engine replacement

FWIW - I did back to back cylinder tests and got very different results. 1 st test showed 2 weak cylinders and the second showed the previously weak cylinders stronger than the stongest cylinder from the 1 st test. It was much more consistant after the second test. Also nothing changed between tests and were done within about 2 min. of each other. I chalked it up to a fluke.
