EFFn A, CEL, cylinder 2 misfire
 
My dad was driving my jeep for about two weeks now since they have been in town. Yesterday, I get in to move the jeep, and I notice the CEL. He mentions thats the first time it has come on. It was about 96 degrees here yesterday, probably higher with the heat index. Would that cause anything to trip up in the computer? It was about 530 and dealers close up at the time, I went to the local autozone.

As I turn it back on after auto zone tech is done, the CEL turned off. Im still taking it to the dealership today.


Any thoughts on what could cause that to happen?

3 things can cause a misfire.

Lack of fuel
Lack of quality spark
Mechanical problem

What year is your Jeep and how's my miles are on it?

2012, 5500 miles, it had about 1/4 tank at the time. tech mentioned that it could be a spark plug, but ruled that out being that the jeep is still new.

I had it in for the second oil change about 100 miles ago. At first, i thought maybe that forgot to reset the light?? but it wouldnt cause that error code?

Based on it being a 2012, my money is on it eventually testing out to be a head.

I just got back from the dealership. As I was entering the driveway, dealer called. He said that he spoke with chrysler and they said to flash the PCM. Although he stated, "I want to prep you that it may need a head replacement if the CEL comes back on."

I never once commented on how my '12 jk was awesome and did not have the dreaded tick because I didnt want to jinx myself. :banghead:

now im going back to pick it up.

Might be a bad coil. I had one go bad on my new Challenger.

The service tech is going to be correct. You'll need a head in the near future. After that, you'll be fine.

Seriously, don't sweat it, better to find out now and get it fixed than later. I don't care what you drive, every piece of machinery out there runs the risk of some part failing. Chrysler will fix it and you won't have too much to worry about in the long run...enjoy that fun vehicle.

BTW, I prepped my son for the fact that since he's got an early to mid '12 model Wrangler, if his CEL indicator comes on, take it to the dealer and let them deal with it, don't worry to much about it. I just don't want the CEL coming on while he's mid way between home and his first duty station in Charleston!

True. Its a fun vehicle and I'm loving it with top down and doors off. Im not concerned about the dealer keeping it for a few days to work it out, as long as I have my rig back in good shape. I've had it for 1 1/2 years now but 5700 miles on it. Obviously, best that this comes up while under warranty than without.
