Cylinder problems 05 Liberty Anyone else?

I am currently driving a 05 liberty, just bought it 13 months ago, only has 56 thousand miles on it. And has been in the shop off and on since this summer. Check engine light came on in August, took it to get checked, came up cylinder 5 miss fire. Replaced spark plugs, light came on about 3 weeks to a month later, read again new engine coil. Again about 2 weeks later the light comes on AGAIN. I take it to the dealership down the road to get it looked @ and he said that he has been seeing a rash of problems with the one cylinder miss firing. Took it back to my mechanic and he preformed a compression test, sure enough Cylinder 5 is not holding full compression like it should. Has anyone else had this kind of issue?

Make sure it's not the coil pack on top of where the sparkplug is located.. the advice I can give u is the coil packs are so damn sensitive and they cost like $50 a peace.. when I was changing my spark plugs one of my coil packs rolled off my fender and kaput it went...

Mark a coil pack with a piece of masking tape marking the possibly fried coil pack..

Now go to cylinder #6 pull it off then put it on #5 and put the messed up coil pack on the #6 ... Then fire the car up I bet cylinder 5 is gonna be OK but then the 6th one is gonna miss fire..

I am having a similar issue with misfire cylinder 6. It only happens on a colder mornings. If turn the jeep off and start it again then it no longer misfires and stops throwing the code. Rest of the day no issues next morning if it's cold happens again.

Bad plugs can cause misfiring when cold, and be OK once warmed up.

Unfortunately the original poster said that cylinder #5 isn't holding compression. That cylinder isn't usually the one that goes bad; that distinction goes to cylinder #2, the front one on the right side. My guess is either a stuck valve or loose valve seat preventing the valve from sealing.

Not cheap but also not a terribly difficult repair. Especially since the left side cylinder head is much easier to remove/replace.

Pull ur #6 plug and put a new plug in. After that if its misfiring still try swapping out the coil pack with one that u know works like #3 or something.. that should tell you something..
