Good morning, have a little problem with the Fiesta (1.25 – 55kw – 98 – 70,000 km) of my girlfriend. Hope you can help me further, since I want to get the car fit today. The engine runs quietly, no fluctuations in speed, hangs well on the gas. No noise or similar. At full load especially in third and fourth gear the engine locks off at 3500 revolutions (similar speed limiter). It is like a wall that cannot be overcome. I have no idea. I have already changed the fuel filter, all cables are fixed, vacuum hoses are not leaking in the exhaust system. No warning light of the motor electronics. Look forward to your answers !!!! Many greetings !!!!!! Projector…
