misfire issues

[joey]

So we have a new VSS, new champion plugs, New Magnacore wires, you have cleaned the MAF and still getting the misfire. I am starting to wonder if it is either fuel related, or a bad coil pack.

I would plan to replace the fuel filter, and also check the fuel pressure at the fuel rail.

Also might not be a bad idea to inspect the coil pack... look for the plastic coating torn, worn or pin holes.
