Tinny sound from 2k-TJ
 

I had asked about this issue in a previous post and wanted to share my
findings in case anyone else has the same problem. What I thought was
sometning loose or vibrating like a tail pipe or heat shield turned
out to be me lugging the engine at low speed. I have the 307 rear end
and very seldom use 5th gear unless I hit 70 mph or better. With gas
prices being what they are I fond myself staying at 55 mph in the
right lane a lot more often and in general driving a lot slower.
Evidently , you just can't drive a TJ with that rear end around town
in 4th gear at 40mph. As soon as I got the rpm's back up and changed
my shift points in 2nd and 3rd the vibration/tinny noise disappeared.
So much for trying to drive conservatively...

Sounds like it could be the cat... gone through any cold water with a very
hot catyletic converter lately?? my ZJ does this when it doesn't have much
torque applied... I jus purchased a nice high flo cat for her and a
Pacesetter header...lookin' forward to the increased air flow.

It's Minnesota so anything is possible. I honestly don't remember
having to keep the engine wound this tight but the tinny/harmonic
noise is gone. Thanks for the post, I'll keep a close watch on the cat
to see if the noise returns or gets worse.

Re: Tinny sound from 2k-TJ
 

I'd check the cat. That's exactly what my TJ did. Don't let it go too long
before you get it looked at. My TJ got to the point I could barely drive it
(and it goes from driveable to not FAST). And don't forget -- 7 year, 70k
mile warranty on the emissions stuff -- no matter when/where you bought it.
The dealer will inspect for free and replace for free if needed. They won't
advertise that, of course, but as I understand it they have to do it.
