I am somewhat familiar with code 21. But I would start by clearing out the ECM codes and see what returns. I am sure that the KS code will come back. The code 21 is like it say, there is a problem on the primary side of the ignition; power transistor, ignition coil, resistor/condensor, and quite possibly the distributor itself. A scope check of the ignition signal on the primary igntion side of the coil should be able to tell you what is going on. Sometimes if the connectors aren't pushed together completely you can get a code 21. I would start there and work my way up.
