What is your question?
Car drives fine at low speeds, but when im driving on highway doing around 100km it feels as if im applying brakes, drops about 5-10km then it will then go back to normal , all while keeping the gas pedal in the same position. it does this all the time. the vehicle has only 130,000 km on it. there is no error codes on the vehicle

More than likely it's the oxygen sensor. I'm a little surprised it hasn't thrown a code, but that could be a different issue. I had the same issue with my '92 spirit, and that is what it was. No problem, except at highway speeds (100km/hr). Disconnect the oxygen sensor and try driving it without it for a bit. If that seems to work (it will kill your fuel economy, so don't do it for too long), then you know what your problem is. The oxygen sensor is located at the back of the engine bay, in the centre. You will have to remove the air filter housing to get at it.
Yeah a full tune up, 20,000km ago
