The past two days i have noticed that after driving for around 15 miles (right before I get to work) that I am getting a high pitch buzz through my car stereo speakers. It basically sounds like th supercharger through my speakers and even goes with the RPM of the charger. Its obviously interference but I am not sure how I am getting it.

I just re checked the torque on my plugs two weeks ago so I know that they are OK. And I have been running IK24's for the past 2+K miles at 8 lbs of boost.

Any thoughts or help would be appreciated.

 

It's not the supercharger. It might be your alternator.

 

Check the wiring on your ESM.

 

Do you have an aftermarket amp/stereo in the trunk? Was it disturbed when the fuel pump was installed? If so, check your cable routing there 1st.

 

So you think the alternator might be going out Sideways?




The car has been fine for three months and then all of a sudden this started two days ago.
My ESM is soldered and shrink wrapped, I doubt it is the problem as I do not see any check engine. I will however check my wiring on my amp in my trunk.

 

Check your Grounds on your Radio and Amp, make sure they are on bare metal. Double check your Signal cable from your amp to your headunit and make sure it is run down the opposite side of your car that the Power wire is.

 

noise injection on a ground or signal cable.

 

I have that problem since my install also.

 

hmmm...has me thinking. Maybe I should listen to the radio instead of the CD.

 

It was happening on CD's also.

I found that my speaker box was shoved against my RCA input cables and for some weird reason it was causing the problem. I simply moved the box and wiggled the wires and the problem has gone away.
