I've been trying to troubleshoot this issue with my 2006 Dodge Ram 1500 5.7L Hemi for about a month now. I keep getting the code P0306 (cylinder #6 misfire).

Here's what I've done so far:

-Replaced all plugs
-New Coil Pack on #6 (I moved the new coil to multiple cylinders to make sure I didn't get a bad one)
-Swapped injectors
-Ran Compression Test - compression is good

I took it to the local Dodge dealer and they found code P2317 Ignition Coil Secondary Circuit.

Any ideas???

Any help/suggestions would be appreciated

 

Usually after all that has been eliminated, you find the issue in the wiring or a ground by the PCM or rear of the engine block.
