Ford Fiesta dashboard wrench sign, unstable RPM needle, and jerking issue possibly related to throttle body on Ford Fiesta

Some Ford Fiesta owners report experiencing dashboard wrench signs that may indicate issues with the powertrain or transmission system. These owners have noted unstable RPM needles and jerking sensations, which could be linked to problems with the throttle body, a critical component that regulates air intake and affects engine performance. To resolve these issues, some owners recommend inspecting the throttle body for dirt buildup or malfunctions that may be contributing to the erratic RPM behavior. While some may choose to check for visible issues themselves, others advise consulting a mechanic for a comprehensive diagnosis and repair. Ignoring these symptoms can lead to further complications and potentially more costly repairs in the future.
