I've got a 2014 Dodge Ram 1500 Express with a 5.7 Hemi. About a week ago I got an engine code P0308-missfire on #8 cyl along with a P2323 code which has to do with low coil voltage. The truck throws a check engine light and I get a dead miss on #8. When it first started, I could shut the engine down and restart and the miss would be gone for a while--maybe an hour, maybe a day--but it would come back. Now when it sets code, the miss stays. On a cold start, the truck runs fine for about 20 miles, then it throws the 2 codes and I get a miss on #8. I live quite a ways from my dealer, so they recommended that I have my guy replace the coil and plugs on that cylinder. No joy-same thing happens. I took it in to the dealer. They checked the coil and wiring for continuity and resistance and then swapped holes with the coil--still sets code for #8. Then he replaced the PCM. Still does it. The mech pulled the valve cover and motored the engine over while he watched to see that the cam was lifting the valves. He noticed nothing unusual. There is much head scratching going on by all involved and he has a call in to the engineers at Chrysler to see if they've seen it. Any of you folks seen it?
