New at this so I hope I am posting correctly. I have finally started working on/modifying my 2004 LJ. It is/was bone stock. My plan is to be able to daily driver, tow behind motor home and moderate trails. I am going to run 33x12.50 with a 3 inch lift and 1.25 inch Savvy body lift. I have installed the Savvy shifter cable system, 1.25inch body lift, 1 inch MM lift and Savvy under armor transmission lift (tummy tuck). All is good with this phase except I am getting a vibration inside the Jeep at idle. No vibration at all driving.
Also, I installed new spark plugs , changed oil/filter, thermostat housing and thermostat, hoses, etc. Now i have a rough idle that goes away immediately after I start moving. Purred like a kitten before the plug change.
I grew up in the 70's working at a local garage, racing and playing in the dirt/sand here on the coastal area of southeastern NC. So I do have some knowledge of the mechanics and fabrication. That can be good and bad I guess.
I just sold my 83CJ and bought the LJ. I think it will be more user friendly for my wife and I. Looking forward to going out and enjoying the off road community. Any suggestions would be greatly appreciated.

Did you verify clearances between the transfer case and tub? Transfer case cut be rubbing against the tub at idle

What spark plugs did you install?

I might need to go back and check. I thought i had about 1/2 inch at the closest point. Got spark plugs from NAPA. I asked for factory spec plugs.
 
For the tires I went with 33”x10.5” and think they look pretty well. Just throwing it out there. My lift is 2.5” which ended up being slightly more.

Another positive experience with 33x10.5. Like the weight reduction and better on road driving compared to the wider tires. Haven’t had any issues at all with traction offroad when I air down to 15psi.
