One the spark plug wire test, when you remove the wire, and it dies, the opposite cylinder is not firing. If it has spark, check the compression, compare it to the other cylinder, if compression is good, then remove your valve cover and check the valves, you can have a broken rocker or a pushrod that has come loose.
OK, but you can have compression, even if the valves are not moving.
