Sounds like your thermostat ground is not on. Got the same buzz from the relay under the dash on my 91 hatch when I forgot that ground. Can't hear your sound clip either.

Code 14 is your Idle air control vavle (IAC). Fisrt hake sure you have it plugged in. If so, here is a little more info on troubleshooting it.
