Yes Stevieturbo, i have some misfires at iddle and low revs,that now it seems to be solved touching in the flywheel sensor, and i want to know if there are something wrong in the test.
All the other oscilloscope test that i have seen, show many spikes, so,how mine it's flat, i have a doubt

It's flat because the engine is running and idling smoothly. Certainly from that snapshot everything looks fine.
The up/down traces you see are with the engine cranking and not starting, hence rpm rises and falls each time compression is seen then passed hence the traces go up/down
