Excuse my ignorance; but is the PCM and ECU the same thing and is it difficult to replace?

Thanks

Its the same thing-disconnect the negative battery cable then find it and unplug the wiring connectors-Bear in mind that you might have to go thru a computer relearning process after replacement due to battery disconnection.
