Code 42 is a short or open of Ignition Control Mobule circuit and replacing the module would not solve the problem if it is the wiring that is at fault. You need to be checking the wires for shorting or break.
Code 67 is for the TCC solenoid circuit. Diagram shows the schematic. Ensure you have battery voltage and the Tan/Black has continuity to PCM.
