Ok so I noticed today that I have a rattle/vibration comming from either the engine compartment or under the passenger seat at between 2 to 3k rpm under accelleration only... sounds like either a valve is loose or the exhaust is vibrating from the collectors or from the cats,, it just started out of nowhere and its got me worried... no check engine light or anything lit up on the dash... anyone else have an idea... just had a 3.14 rc lift and 35s put on Monday..

Without having the chance to hear it I'd guess that its exhaust. I've picked up exhaust rattles / shake a couple of times and took it to an exhaust shop to get it fixed. I hope that's it because at least it won't cost much to fix.

I did crawl under mine and everything felt intact and nothing was loose..

What heat shield was broken? Mine is doing it now too, but I think the cracked drivers-side exhaust manifold finally broke.
