It sounds like you need to pick up a Haynes manual from your local autoparts store. There is a great section on not only how to run your ECU codes but what the ECU codes are referring to. There are a few referenced right on the unit. I am not within reach of my Haynes but if you purchase one you will have everything you need.

Good luck!

How is a possible problem in the ignition which is detected by the ECU not able to "make it run craping"?

Many things can cause a code 21, according to the FSM:
-harness between ECU and ignition coil
-power transistor
-ignition coil
-high tension cables
-spark plugs
-distributor
-ECU
