I'm not very mechanically smart when it comes to vehicles so i need your help to find out what this noise is and how to fix it... I took my skid plate off to check out my exhaust, because I was looking for a new aftermarket one, and everything just dropped down so i jacked it back up and put the plate back on. my Jeep sounded fine for a while and now it makes this louder than usual idle noise now. i have a 05 jeep tj btw.
