I bet it also feels like it wants to stall as well. I think my car was at around 65k and it did the same. It is the spark plugs and the coil. My mistake was going to the dealership where they charge you too much. Any experienced mechanic can do it. Changing the coil is also in the manual.

1) Check all the vacuum hoses for a leak in the rubber hose or a hose that isn't connected. Vacuum leaks cause motors to shake and stumble on acceleration.
2) There's a plastic T connection on the back side of the engine behind and under the air cleaner box. That T connector joins together three air hoses of different sizes and is prone to breaking from heat stress. Only a Subaru dealer will have this part.
3) Even though the spark plug wires are new, you may have a bad one. Don't waste your money on cheap parts; they cost more in the long run.

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

Check the air inlet boot going from the air filter to the intake for rips or holes. If rips exist, this would allow air to bypass the filter and mass air flow sensor and will lead to a check engine light appearing. The code would read "too lean, bank 1." If this problem is allowed to continue for long periods of time, the EGR ports will have to be cleaned out and maybe even the intake.

SOURCE: I think the coil pack
The coil pack should should be the device you plug your spark plug wires into. if it is round, then it is a distributor not a coil pack, if it is square and looks like there are relays coming of it, it is a coil pack. to replace this, you simply mach the wires to the corresponding diodes on the new device, unscrew the old one and screw in the new one. plugging in any connecters you might have forgotten.
