If you're experiencing idle issues on your Jeep Wrangler TJ the most likely culprit (and the first thing you should check) is your IAC (Idle Air Controller). Often times the IAC gets very gunked up causing the Jeep to idle improperly. A simple cleaning is usually all it takes to get it running as good as new.
If you end up needing to replace your IAC valve (they do fail on occasion), you can find the part numbers (and the links to purchase them on Amazon) below:
2005-2006 IAC Valve (Part # 4861552AC)
1997-2004 IAC Valve (Part # 4874373AB)
There is no need at all to remove the throttle body to clean the IAC. This is probably one of the easiest and cheapest things you can do.
Below you'll see a diagram of the top of your throttle body with the IAC sensor labeled.
Take your IAC off (it's held on by two small torx screws). Clean it with your throttle body cleaner, this is what it will look like before and after.
Then take off the IAC housing and both sides (house and throttle body). clean that too. before and after...
Put it all back together and you're good to go. Very, very simple. It doesn't get any easier than this!
