A tip of the hat to ronjenx for a clear and easily repeatable writeup.
Mine started with the lightning bolt error recently. My 08 was not throwing any codes. I went to my local jeep dealer and got a new PCV valve for $11 and did the swap.
Seems to have done the trick.
Mine had a few drops of oil on it, don't know if that is a symptom of a bad valve or not.
In any case, the whole swap took about 10 minutes, very easy to do. I used the tie wrap trick and it came right out. The oil on the valve might have helped
Thanks ronjenx

(I little bit of "I didn't think of it" may apply, too!)

Did mine today.
I didn't remove the plug wires, I just lowered the coil pack out of the way. Wasn't able to do the ziptie, didn't have any thing but little ones. So I just used a pair of visegrips and put the screw driver through the larger part of the jaws to pry it up. Work very easy.
I did find that the hose was quite oil soaked. So I hope this means that it really was bad, and will help lower my oil consumption.
Thanks for the write-up!

I think I have to replace my pcv valve. I've got 54k on my 07 and every once in a while, as I am stopped at a red light. My idle drops suddenly and I can feel a minor shake as if the motor is going to kill and then it goes back to a smooth idle. Is this a common symptom of a bad or worn pcv valve?

Great write up thanks! Heading to lordco to see if I can get this part later.
Edit- no deal at lordco. They dont list it. Damn off to the stealership.
