I replaced plugs, wires and coil. I'm still experiencing misfires. Could the problem be the PCM?

The P2305 trouble code is a generic powertrain code that indicates a problem in the ignition coil "B" secondary circuit. So, it will be a wiring issue or a bad PCM.

Here is a guide to help you test the wiring between the coil and PCM and the PCM/coil wiring diagrams below to help you with the test:

If the wiring is good here is how to change the PCM out, this guide may help as well. You can get a preprogrammed unit by searching Google or Ebay.

Check out the images (below). Please let us know how it goes.
