The video below was taken from inside my jeep -obviously- while parked with the motor running.
You may have to turn the sound up but you should hear a high pitch whistling in the background. That sound is not an artifact of the video recording. My jeep is actually making that noise. The recording does seem to have amplified it some because it isn't that loud in reality. If the radio is on at moderate volume you really can't hear it. It does also happen while driving but that is a little harder to record and it can be harder to make out above the road noise. Doesn't seem to vary with throttle or anything like that but again hard to tell due to how faint it is and engine/road noise.
I've been there and done that with the water pump issue (at only 500 miles) and I don't think this sound is that. You cannot hear this outside the jeep unless you lift the hood and listen real real close then you can maybe just barely make it out above the engine noise.
I've done some searches and most results are for TJs or are a few years old at this point. Possible things found in my searches - vacuum leak, normal noise for this throttle body design (not sure what that means but I think this would come up a lot more if that were the case).
I haven't been able to track it down and its driving me nuts. 2014 JKU Rubicon, no engine or performance mods or anything like that.
I just wanted to see if there were any other ideas or if anyone has experienced this lately and what you did about it. Any troubleshooting tips to track it down?
