I can not find P2314 in the paper Crossfire 2008 Service Manual.

Did you allow the scanners to work through all the modules or did you just scan one or two particular modules?

Seeing that the car is running well I would scan all the modules, writing down all the codes active and stored then clear them all. Drive the car as usual for a couple days and then scan again to compare listed DTC.

P2314 on other Mopar sites indicates a spark plug/spark wire problem; on our cars I would think misfire, but you haven't indicated that with your scans. Scan all the modules and then clear all DTC and give it another try. GOOD LUCK
