I own a 2006 3.7L grand Cherokee and my tune up consists of spark pug replacements (6) for me, differential fluid change, ATF fluid change (no flush), and PCV. If you have a transfer case you will need to change that as well. good luck!
Generally I change platinum plugs at 100K and regular plugs at 50K.
The plugs are under the coil packs that are on the passanger side of the vehicle. This is of course if you have the 4.0 engine. I would need to know more about your vehicle to gie you the best answer.
