Changing spark plugs on a Subaru is no different from changing spark plugs on any other car. You may have to remove parts of the air induction system to make access easier. Be sure to check the gap on the new ones and use anti-seize on the threads.
The spark plug gap, for your 2000 Subaru 2.5 liter engine, is .007. Most spark plugs will be pre-gapped by the spark plug manufacturer.
You may have a bad valve, did you replace the rotor and cap? Check the cap for cracks.

It is important to know the location of the spark plugs while owning a car. In a 2002 Subaru Impreza WRX there are spark plugs near the bottom of the engine block on each side of the car.
I would imagine that you are referring to a high voltage electrical distributor on the engine rather than an automobile distributor. Your Outback doesn't use one. Look under the hood and locate the spark plug wires. Trace any of them back away from the spark plugs and you will see that they plug directly into the coil on top and near the front of the engine.
Generally, to replace spark plugs on a Subaru vehicle, the spark plug boot should be removed. Then, the old spark plugs should be removed using a socket wrench, and replaced with new ones.
that would most likely indicate that your 3rd cylinder is not firing correctly or firein late A.E. "missfire" i would first check your spark plugs, to see if their good, and if they are i would check your timing
