Recently, my Subaru developed a misfire. I had the code scanned and it was P0302 – cylinder #2 misfire. Check out my blog: http://mercedesdieselguy.blogspot.com.

Great videos man, I have a 96 legacy wagon.. how hard is it to change speed
sensor? Mine is automatic
Thanks for the input. I haven’t had a chance to post this week’s videos
yet, but I installed a new injector: no effect. The car has brand new
wires, plugs and coil in the past week, so that’s not it. I did a
compression test (video coming soon) on Saturday and found that Cylinder 2
had low compression. Based on the specifics of the test, I diagnose a
burned exhaust valve.
Not quite. Ended up replacing the cylinder head. Check my more recent
videos. 🙂
I’m thinking about doing a HG job myself however you don’t recommend it as
DIY project. Can you shed some light with more details why this is not a
DIY project?
Hope it’s the injector, keep us posted.
Well, I did replace the cylinder head and gasket, but it’s a really
involved process. I did it myself, but it really is advanced DIY. I
wouldn’t advise a beginner to tackle the job.
Hi. thanks for the tutorials they are helpful. I have a 96 legacy that is
reading P0303. I’ve changed the pcv valve, the spark plugs and the wires.
Im headed to purchase a new ignition coil pack today. My engine light seems
to kick on when I have to go uphill, or go over 40. Any suggestions on what
else it could be if its not the coil pack?
You roll with the punches. Nothing to do about it but that. I’m probably
going to replace the whole cylinder head and call it a day. In the
meantime, I own three cars, none of which are roadable, and am taking the
accursed commuter train 🙂
There isn’t a lot of room to work in there, a lot has to be removed
(including the intake manifold), and there’s a very specific torque
sequence that needs to be followed.
Ouch, that’s no good. Sorry to hear that!
Time for a trade in … Lol
What’s the most difficult parts of HG job? Some detail explanation would be
helpful.
Thanks for the tip. I do have a multimeter, but I wouldn’t know exactly how
to do that. I’ll check into it, though. I do have a rebuilt injector on its
way, either way.
If the ignition coil does not fix it, I would recommend running a
compression test. The problem COULD be the injector on that cylinder. But,
in the end, I had low compression on one cylinder. I took a chance and
replaced that cylinder head, thinking I had a burned valve. But, less than
a year later, the problem came back… worse, suggesting I needed piston
rings in cylinder 2. A compression test will tell you whether or not you
have a bigger engine problem.
Doubt it’s a mechanical problem with the engine, looks more like an
electronic issue to me. Injector, possibly. I’d be checking all the wiring
not just from the coil to the plugs but also from the ECU to the injectors
& coil pack, particularly the harness in the engine bay. There’s a lot of
corrosion in that engine bay, it’s not difficult to imagine that contacts
in a connector might have corroded and caused the issues. Best of luck to
you, hope you sort it!
you can measure the resistance of the solenoid in the injector with an Ohm
meter. if it is infinity, the solenoid is burnt. If it is 0, it is
shortened. It probably has a spec what the correct value is.
I hope so, too. New injector ordered – will get here in a day or so.
