Hey everyone. I am a new member. I have to apologize in advance for the long post, but I’m trying to give all the detail to get some help. i have a 2015 Jeep jku. The engine and transmission as completely stock. Not so much as a tune (Just calibrated for my axle and tires size). My suspension and axles on the other hand...hahaha.

I fixed the issue below but think it may have something to do with what I’m experiencing now. I went off roading. It got a little wet, not submerged or anything. On the way home from the off road park the throttle cut out a couple times and RPM fell to zero. A week or so of it doing this with no consistency at all, it did it and stalled. Finally threw a code. Crank Position Sensor! Woohoo!!! Makes sense. I ca he’s the sensor, it never happened again.

but the very next day after putting about 50 miles on it I get two codes...P2308 and P0303. I know they are bad ionization and ignition coil for cylinder 3....but the timing is VERY STRANGE.

so I reset the computer just to make sure it came back and sure enough...55 miles later...I get the P2308 as a stored code and the. A short time later I get the P0303 as a pending code. The rough running on 5 cylinders is not something it did before the Crank Position sensor code was thrown. And now that I have changed that sensor I am no longer getting that code....but now this one almost instantly pops up.


any ideas? I find it hard to believe that they aren’t related.


Thanks

y’all!

 

You could try to change the coil for cyl 3.

 

working on that now. But it seems too weird to be a coincidence.
