AEM UEGO causing major commotion, HELP!!!!
ok, so me and a buddy decided we were going to build a custom fiberglass system in my truck for the newly bought evo.. all is going well until we decide to actually plug in the RCA's into the speaker amp only to be met with a horrid loud ringing through the speakers.. I have wired this car up and down, left and right, every which way to try and get this to stop.. it seems to be when i plug in the sensor to the gauge itself that is connected to the o2 sensor and then the noise starts through the speakers.. i have heard of ground loop isolators and things but not sure if they will work for this problem.. if anyone has ever had this happen or know what could fix this, please throw me a bone.

Is this with the engine off? Disconnect all the leads from the four channel amp, then connect one at a time and see if it does it individually, maybe you can narrow it down to a shorted speaker lead somewhere. I ran into something similar where a tweeter was grounded but caused all sorts of high pitched noise through all speakers, narrowed it down to the shorted tweeter. Where does the ground for the aem piece ground to? perhaps it's shorted to a speaker lead, but doesn't throw ground to the lead until plugged in

Sounds like a bad ground loop, or too much draw for the UEGO tapped from the same circuit the radio is on. Try a different [better] power source for the UEGO. I have mine sourced on a fuse tap in the glove box and all is well.

That is what I was thinking also. If hes running the Uego off the same power/ground as the stereo, you will get noise and/or interferance.
