A higher octane fuel(94+). Shell has a lot of cleaning additives to their fuel, up to four times the industrial standard.
All gasoline today has additives added that help keep injectors clean. There is no more cleaning additive in Shell 94 octane fuel than there is in Shell 87 octane fuel. Using a high octane fuel in a vehicle designed to run on 87 octane is a total waste of money and provides no benefit whatsoever. Once each year add a can of Seafoam, Techron, or any other high quality fuel system cleaner to a full tank of fuel and you will be fine.
Clean fuel injectors help to keep a car running well. A person can clean the fuel injectors on a 2001 Buick Century by adding fuel injector cleaner to their gas tank when its empty and about to be filled with gas.
easiest way to clean injectors is to purchase a good (not cheap) injector cleaner, and add to you fuel tank. from experience, i double dose the amount first time round, then add correct amount to fuel about once a month. this will keep injectors clean and will not damage engine
It's fuel injected and has no carburetor. Use a quality fuel injector cleaner such as Seafoam or Techron poured into the fuel tank every 6 months to keep the injectors clean.

remove fuel rail above the injectors un hook the wire and pop it out clean around the injector before removeing it keep the dirt out of the cyl use alittle grease on the oring when you put the new one in
Fuel injector cleaner that you mix with a tank of gas, doing anything else to your fuel injectors to try to clean them can, and will likely end up damaging the injector itself, or the o ring seals that maintain fuel pressure. I have changed my injectors myself before, and they don't usually come out easily, or without breaking the plastic electric connector. Good old injector cleaner from time to time will do wonders, and keep system running smoothly.
When you replaced the injectors, did ou also replace the O rings? Are the injectors seated down in there OK? Try twisting the injectors a little after you've seated them

Regular unleaded will work for any stock Jeep. I assume you are running a 4.0L (6-cylinder)? There is no gain to be had for burning the expensive fuel unless you modify your throttle body or install serious performance-enhancements to your Jeep. Consider a fuel additive every 5,000 miles or so to keep your injectors clean if you really want to keep your fuel system at its peak.
You need to do periodic oil and fuel filter changes. You also need to keep the intake/exhaust valves adjusted. Once, every two years or so, you can clean the fuel injectors using a purge system that you can buy from Performanceproducts.com.
make sure your fuel tank is free of debris, same thing with all fuel lines and fuel filter
