What year? What engine? I need specs to help you!

Fuel filter, air filter, differential fluids, transfer case fluid, coolant, grease some bushings, rotate tires, etc etc.

If its not a 2000-2001, you should replace the spark plug wires and distributor cap/ rotor for one with brass contacts. Replace air filter. Clean the throttle body and IAC motor... The information about this is abundant on this forum. There is many more things I am forgetting here too. Good luck!
