So Ive had my 03 KJ for almost 4 months. On the way to pick up my SIRIUS b-day present I started to hear this god awful crackling noise. It was drivers side and I zeroed in on the tweeter speaker on top of the dash. I put my hand over it and the noise seemd to muffle. I then used the radio controls to zero in on the front left speakers and no noise. I then turned the radio off, noise was still there. I figured out the noise comes at about 40 MPH or so. (I later figured out it goes away after 80 MPH
) A friend suggested bad plugs/wires or is it coil packs?? I revved the engine in Park and Neutral to around the same RPM as when the noise starts, nothing. No check engine light or any noticeable performance issues. I guess what I'm wondering has anyone expereinced something similar? Is this going to be a costly issue? or is it a stealership only fix? Like always any suggestions/input are always GREATLY appreciated .
