Hello, so I drive the vehicle described above. If I want to give gas and before I was in thrust operation or had to take gas away (speed change) he starts to jerk after a short time (1-2 times) and then he goes on full ballet again. Is it whether I drive down or up toury or whether the engine is warm or cold. (well maybe in the cold bitsl worse) Maybe someone had the same problem or knows the matter Fiesta XR2i! Thanks already. Mfg Marco
