check engine light came on. Code reader said misfire cylinder six. replaced all the plugs with NGK gaped to .040. Same thing. double checked every thing then swapped coil pack from cylinder four. Same thing. However, the coil pack from cylinder six that I put on cylinder four was okay.

Good evening,

You did the basic checks.

I would check the compression in the cylinder to be sure nothing is wrong internally.

Also, it could be a vacuum leak or an injector.
