I bought my 2005 TJ a year ago (had 57,000 miles on it) and finally decided to change the plugs to Autolite Iridium XPs (gapped to .040). Made a big difference in the smoothness of the ride. This is what the plugs looked like with .035 for reference.

No sir, I am sort of a newbie so will look into it. Not afraid to learn.

Edit: just found this YT video. Someone in the comments said that the guy used too much RTV sealant and should have used Motoseal.


2nd edit: this video looks better

You can clean the throttle body without removing it, just buy an aerosol can of throttle body cleaner and do it according to the instructions on the can. Be sure to wipe/clean the bottom side of the throttle valve plate with cleaner too, you get to that side of it by opening it with the throttle lever.
