What could be making the buzzing sound?

First let me tell you I've got a 84 T-bird Turbo coupe. While I have done lots of up grades to it. I have run across this buzzer type sound that comes on at high RPM only. No it is not the over boost buzzer either. I'm only running 13psi of boost and the car rips. It doesn't do it all the the just somtimes. any how any ideas? It sounds like that buzzer when you first turn the car on before you start it. Also my red engine light stays on all the time. I only get the EGR code and KS code but I don't tap to test the KS. Also if you turn of the car the red engine light gets brighter. So I have no clue on it either. Thanks in adavnce for the help.
