I've been searching your forums for some time now, and I'd like to thank everybody who posts. I've learned much from searching and reading through this site, but I cannot find a similar situation to what I've done.
First off, I have a 2005 "Rocky Mountain" Wrangler with the 4.0L Engine and 6-speed manual transmission. I just hit 100,000 last week. I don't do any "serious" off-roading. I do a little back woods driving in the Adirondacks while I camp.
I was in a rush the other morning when I was leaving my house, jumped in the Jeep, and started it up. Problem is, I took my foot off of the clutch while the tranny was in 2nd, and the parking brake was on. This obviously stalled the engine. When I started it back up, there was, and still is, a loud rattle, as if something is loose. Depressing the clutch doesn't seem to make any difference.
When I'm sitting in the Jeep, the sound seems to be coming from under the passenger side floor, but when I crawl under the jeep, I can't hear the rattle over the noise of the engine.
The weird part, and the part that scares me, is the rattle goes away after the Jeep idles for 1-2 minutes.
It goes away when I accelerate in neutral, but comes back when I idle back down. It also seems to get louder when I reverse, before letting the engine warm up.
I've crawled under the Jeep and tried shaking everything I could, hoping something was loose. But I've found nothing.
Everything I've found online describing something similar has seemingly major differences(noise going away when clutch is depressed, noise not going away when engine is warm, etc.)
Thank you in advance for any and all help.
