CEL in 2000 Legacy GT wagon

Code P0303 Cylinder 3 misfire. I replaced spark plugs, plug wire, coil and fuel filter. Idles rough and blinking CEL under load. I just did a compression test and it was over 200psi. I never have done one before and that seems a bit high from what I could find. Does anyone have any ideas what could be wrong?

 

Could possibly be a sticky valve, try putting in a fuel additive that's cleans carbon out.

 

First thing I did is throw some Amsoil Pi in.

 

No lightened flywheel? If not then I'm kind of stumped.

 

Very stock car with 128k on it. It does have some minor oil leaks. I think the cam seals have backed off since the timing belt was done at 110k. Something else I read about was an ignitor but you would think it would be more cylinders showing misfires. I'm going to get a reader again and see if there are more codes now.

 

Moved the fuel injector to cylinder #1 and the misfire code followed. I have always dumped a half bottle Amsoil Pi when I have changed the oil. So injector service and clean or new ones?

 

I'd vote for new ones, just to give yourself the peace of mind.

 

junk yard, grab a set of injectors there, done

 

So do I walk up to any old Subaru and pull the injectors Mr Done? Rockauto has prices ranging from $30 to close to $100 for each injector and it seems to make a difference on the type of transmission. A clean and service for all four injectors is close to $100. Is there a way to test them for functionality before this?
