code 18

[94conv.]

does anyone know if the code 18 is for the optispark or the injector circuit on a 94 LT1?

The code 18 must have been set when we unhooked the injectors to try and find the miss, once we got the scan tool to clear, it didnt return till we unhooked them again, in the morning we're checking for a fouled plug, hopefully that is it or its back to tearing the darn thing apart again and having the dynaspark checked, I just want to darn thing running again, its been forever and Im loosing patience
