I have the code 18 with KOEO, and KOER I have the codes 12, 21, 16 and 13 (the engine was not hot), because there is no code 18 with the engine running?. 
In previous messages the code 18 is the wiring or TFI, I think the wiring is not because the last few weeks had problems with the distributor and TFI by a loose connection (screw missed a TFI), this caused the car to go off at any time, but once it set the screw and there has been no failure, the only thing I regret is that the car lacks power.
as I can test the TFI?
and tested the connections with the SPOUT, also disconnected the connector that goes to the TFI and do the test again, you receive the code 18
