Customer Question

Recently had a new PCM installed by the dealership. Jeep has been running very well since then. However for the last few weeks, the check engine light has been coming on intermittenty, without any problems with the running. Had it checked at our local Advanced Auto store and the code was P2308 Ignition Coil C Secondary Circuit. What is your assessment and what do you advise?

the number 3 ignition coil is likely the fault... I would either replace the coil or swap it with another cylinder and reset the light if you swap it and the misfire moved it proves its the coil
