90% of the tune a misfire on these engines is coil/plug related. I can't belive anyone would jump to injector or pcm first before even doing the coil. Is it the same cylinder misfiring or a different one? These tend to start to fail one after the other until all 8 have been swapped

Exactly as Andrew said. If one coil or coil pack (whichever the case) has failed it's best to replace all of them. When one fails the others are soon to follow. HTH. -Jim

isolate the miss fire to the cylinder. then figure out if it misses at idle or under load. small vacuum leaks in the manifold can cause misfire at idle but not usually above idle. it may be as simple as incorrect gap in the plug. or valve sticking open causing low compression misfire.

I have changed all coils and plugs number is still misfiring

When does it miss fire. Under load or at idle or all the time. Also does the check engine flash or jus comes on and what codes do you have
