14: Two or more successive erratic Profile Ignition Pickup (PIP) pulses occurred, resulting in a possible engine miss or stall.

18: SPOUT circuit open or spark angle word failure.

23: Closed throttle TPS voltage higher or lower than expected.

63: TPS circuit below minimum 0.6 volts.

14 and 18 may be related to you changing out the TFI module. 23 and 63 may be caused by someone touching the throttle pedal during the test, or a disconnected TPS.

Disconnect the battery for around 5-10 minutes and start it back up and see what codes you get. Make sure you let it warm up fully before the test.
