Oldsmobile Cutlass Ciera engine dies at low speeds, especially in reverse on Oldsmobile Cutlass Ciera

Some Oldsmobile Cutlass Ciera owners report experiencing engine stalling issues at low speeds, particularly in reverse, due to several potential causes. These include a dirty fuel filter that restricts fuel flow, leading to stalling, and problems with the idle air control valve that may require cleaning to maintain proper engine idle speed. Additionally, an Electronic Spark Timing (EST) code, specifically a number 42, could indicate ignition system issues contributing to the stalling. Owners also note that air intake system problems, such as a dirty air filter, can disrupt engine performance. Regular tune-ups and maintenance, including replacing the fuel filter and checking for vacuum leaks, are essential to prevent stalling. Furthermore, cleaning the throttle body can enhance airflow and engine operation. Lastly, conducting an engine compression test can help identify any internal engine issues that may be affecting performance. Addressing these concerns promptly can help resolve the engine stalling problems in the Oldsmobile Cutlass Ciera.
