The coil pack on a 90 legacy almost never fails.I would look at plugs and plug wires first.Second,If the vehicle has an auto trans .I would suspect injector failure The 90 to 91 legacy 2.2l( auto trans only) has a known injector issue.Not really sure if the later is a a good job to try your self though.
