Hey, so I have a 2006 Jeep Liberty Sport manual transmission and I'm getting an issue that just started a few days ago. I can't figure out what it is. The issue only happens when I'm accelerating and it happens between 3000 to 4000 RPM's the sound sounds like a wind up toy and it sounds like its coming from the middle of the dashboard. Can't be heard from the outside and is not heard when idling I put the car in park and moved the throttle cable with the hood up and the issue doesn't happen. When I get up to speed it doesn't happen either. Happens with the radio turned all the way down. No shakes no pulls or anything I just can't seem to figure out what it is... Any ideas? The sound never seems to be coming from under the hood.
