the first thing i was taught to do on a random misfire , once you've checked all the easy components (spark plugs and coil packs and MAF), is to do a compression test........that will rule out warped heads & bent valve(s).

I believe you are correct on the ecu.. they are not interchangeable. Only other cheapy shot would be the CPS... worth a try
