Diagnosis check

Let's see.....

Code 14 - Ignition signal - No 'IGF' signal to ECU 6 - 8 times in succession.
Code 31 - Air Flow Meter Signal - Open circuit in VC signal or short circuit between VS and E2 when idle contacts are open.
Code 41 - Throttle Position Sensor Signal - Open or short circuit in throttle position sensor signal.
Code 51 - Switch Signal - No 'IDL' signal, 'NSW' signal, or 'A/C' signal to ECU with terminals E1 and TE1 shorted.

If all this came on at once, this looks like a pretty bad systems failure. You need to check the wire harness for damage. I'd concentrate from where the harness comes out of the firewall to where it wraps around to the front of the engine.
