@cardoc,

OK went out to car, started it up, noticed misfire. Conditions were 63F and dew on ground. ran car for about 3/4 mile, stopped turn car off as i delivered mail. get in car, turn on and misfire is gone? connect codes scanner (OBD Lynx) and history code of P0304. This leads me to one conclusion since wiring is fine to ECM and EVERYTHING is new at #4 (Injector, spark plug, coil) wiring test good between injector and ECM...

@cardoc,

is there any way I can program a new ECM or do I have to drive it to the dealer and have them do it?

well I ordered me a 8 channel Hantek scope for my tablet so, now I am going to get down and dirty with the ECM before I order a new one...

The immobilizer is the problem. Only Subaru can code keys as far as I know. They won't let it loose for the aftermarket. You can search on Rom Raider's forum and see if anything exist over there.

If you know someone that works at Subaru and can sneak out a notebook with the software, have at it. ;)

as I understand it 2010 up immobilizer duties are shared between the BUI, Instrument Cluster, and ECM... so if I do narrow it down to ECM I will completely dismantle the passenger side glove box, remove the ECM from it's mounting studs and lay it on the floor so all they have to do is unplug, replug and then program it to the car.

@cardoc,

Cool and damp this morning, started car, was missing. Turned car off, waited a few seconds and turned back on, was missing a lot less...and miss cleared up at idle within a few moments. I flea bayed a used ECM that will work in my vehicle per VIN.. only $60 so hopefully this will fix it.

also do you know if they make a cooler line repair kit for the pipe that goes from the upper oil pan down to front of the engine? Subaru does not sell that part separate from a $400+ middle pan...

Just a thought . . .

Looking through the thread, it seems that each time there were misfires when first starting, it was in the morning when the environment was cool and damp. Is that correct?

not always but close enough. I gave been through the wiring so I am not thinking it is an issue other than being cool

I was thinking temperature and/or moisture can impact exposed wiring (e.g., leakage) and connector contacts (intermittent contact and/or higher resistance). But if it's been covered, okay.

The Hantek automotive scope might help identify if there's something unusual in the switching signals to injectors or coils. With 8 channels, all six of each can be examined at the same time. Should be interesting, but it would have to be checked when the engine is showing symptoms . . .

today it was cool, started up misfire, turned car off. wait 30 seconds and start again, misfire is much less pronounced. not much moisture
