Engine chokes, constant failure
2005 Ford Fiesta 262000 miles
Good morning all. My car is a Fiesta power 2005 and, for 6 months now, it has been presenting a huge failure, that started by appearing occasionally but is now quite frequent. It seems to be a spark plugs' failure but it is not. When starting the engine there is no problem, but after a while, the car starts failing, it loses power, chokes and I need to accelerate it so that it sets out and be careful because it suddenly speeds up. The engine trembles terribly and, if the air conditioning is turned on, it is even worse because it is ever more powerless and almost stalls, even though this has ne… Read complete

Good morning, the same thing happened to my Fiesta power 2005. It had all the symptoms you mentioned and even the engine trembled as well when the radio was turned on. After changing all the car parts like you did, I checked the computer and it was damged. I first tried repairing it, but the failure persisted. So I replaced by a new one and the problem was solved. You should check the wire that goes from the positive terminal to the relays that are on the battery's plastic box, as this was the wire that damaged the computer in my case because it was loose and, due to a constant bad contact, it damaged on its inside. I suggest you to take your computer to be checked, as every time I scanned it, a coil failure was indicated, but it turned out being that the computer did not send the electrical current to two of the injectors and that is why two cylinders stopped working. Hope it helps.

Your fuel filter must be dirty, you need to change it. If this is not the case, then your deposit might be full of impurities, which might have reached the engine.

CommentNo acelera, enciende pero cuando acelera se frena
1997 Ford Fiesta Motor 1.25 ecu de 104 pines 3500 miles
El problema del vehículo es que no acelera ,le cuesta encender ,y cuando enciende y quieres acelerar ,se siente ahogado y el motor no revoluciona, y hasta se apaga, se le cambió el tps por qué no había señal de retorno hacia la ecu, la señal de 5voltios está presente, la señal de masa está bien , pero cuando se conecta para medir la señal de retorno se queda en 5 voltios y moviendo el acelerador no hay variación,ya se han cambiado 4 sensores tps y aún la falla persiste , quisiera saber si estoy errado en el diagnóstico, quiero medir con exactitud la señal que retorna ala ecu ,cuánto debería ser estando en ralenti y en diferentes modos de aceleracion
