No, they don't work as well as their marketing wants you to believe. That is why most chain auto parts stores don't carry them. Also, your Jeep Liberty has a 3.7L V6

2004 JEEP LIBERTY KEEPS COMING UP #6 cyc miss fired.


When I had a misfire and could not find the problem, I would drive my car at night to an area where there were no lights near by. I would leave the engine on and open the hood. You can see if there is any arcing from from your spark plug wires or any electrical wiring to the engine block. Also, you may want to consider this: How long has it been since the spark plug wires were changed?

Cant get no spark frome plug


can you tell us what engine is in your jeep liberty? most likely you have the 3.7 v-6 but we can not assume that. if you have the v-6 with a coil for each cylinder then switch the coils from a known good cylinder and see if the same cylinder is still misfiring. if so then replace the coil and the spark plug and or all the spark plugs. those coils are prone to failure.

Changed the spark plugs to E3's about a day later the engine started to idle rough and now the check engine is on


Sounds like bad plug wires, and/or one or more wires may not have been clipped back on all the way and came off. Old plug wires do not like being disturbed.
With plug wires, its the age, not the miles. Spend the money for wires from a Jeep dealer. You'll thank me. Hope this helps.

The Jeep comes with Platinum plugs from the factory.
And also a little secret-They are guarenteed from the manufacture for 1000,000 miles
Your Jeep should have Champion plugs in it.
