Mustang GT VMP Odin Supercharger Misfire in Cylinder 4

Unread post by Denver_SVT »

Hello,

What can cause Mustang Coyote Gen2 to through an error code P0304 and P0316 ?
Can a tune cause it or it's mechanical failure such as ignition coil, spark plug or internal failure in Cylinder 4?

Thanks.

We did a crank relearn and still same issue. We contacted SCT Tech and the said “it could be a checksum missing or miscalculated after the flash and they said they have seen that more than once and it’s a Ford issue.”

Is there away to try in the tune to see if it will help not detecting the misfire in Cylinder 4 ? At least to try and see.

Just to let you know that when we get the spark plug from cylinder 4 it was rich ( black color ) while the others are fine.
