I ran a test at Auto Zone:


 


It came back as ignition coil, based on:


 


PO301


PO302


PO303


PO304


PO400 egr


P1100 low input.  


 


I'm thinking wires as when it warms up it runs well.  I don't think I've changed them since I bought it, a year ago.

NGK or Subaru Wires.

NGK Plugs, Copper Core

 

Subaru Coil if you need one.  I have a bunch of Subaru Coils if you end up needing one.

 

What year and what engine?

 

Unlikely that they all failed at once, but start with a good visual inspection of the wires and go from there.

If the wires are old I'd replace them anyway. they are good preventative maintenance. All those codes at once would more likely be coil.

 

I've got some coils laying around too. They aren't a real common fail point so a good used one is usually the way to go. let us know the year/engine or part number of your coil and one of us can probably set you up.

No. If it were a coil you would have misfire on 1/2 or 3/4. Misfire on all four cylinders is probably camshaft timing. May have jumped a tooth on the crank.... could be other problems maybe. It's not likely that both halves of the coil went out at the same time. Usually when they fail they just don't work at all on one half. Doubt that's your problem.

Once I got the coil today, I pulled out the old one and then found it was not compatible.  Good guy at Advance came out who is working on his mechanic certification and the wire was literally broken down corroded in the socket.  So once I cleaned out the coil receptacle hole, I could put the old wire back in, no bad stuttering but the wire will need to be replaced.  I heard Rock Auto is good, beats the $50 plus I see at Advance and Auto Zone.
