Before you start throwing more parts at it, take some vital signs like compression. Smoke test the intake system.
Cylinders maybe getting carbonized. I posted many times on how to remove the carbon with a Seafoam soak.
How old are the Fuel Injectors and O2 sensors? The two can degrade performance without any other symptoms or DTCs. I would go after Injectors before O2 sensors.
It could be a clog in the exhaust system. When was the last time the resonator of muffler where replaced? You can check for a clog in the exhaust system by removing the front O2 sensor. If it runs much better there is probably a clog in the exhaust system. Don't be quick to blame the Catalytic converter. It could be the resonator or muffler.

It's a European car, probably some stole away Gremlins that grew up.
