My iacv is making a noise everytime I attempt to start my car.... Anyone ever have this happen? It sounds like that ringing noise you get in your ears after a concert. I had to extend my iacv wires to reach its new location, but I don't see how I could have messed up the wiring. If I had accidently switched the wires black/yellow with the blue do you think that would make it act funny? Even though I take care with these things I would assume that you could theoretically switch the wires on the iacv and it would work the same. IDK I need to get the multi-meter out and make sure all my **** is straight, just wanted to see if anyone elses iacv humms and if they figured out what was doing it. Thanks
