Cadillac CTS sputtering issue during acceleration with no engine light on Cadillac CTS

Some Cadillac CTS owners report experiencing sputtering during acceleration without the check engine light illuminating. This issue may stem from various factors, including fuel system problems such as a clogged fuel filter, failing fuel pump, or dirty fuel injectors, which can lead to inadequate fuel delivery. Additionally, ignition system issues, including faulty spark plugs, ignition coils, or malfunctioning sensors like the crank or cam sensors, can cause misfires and sputtering. Airflow restrictions due to a dirty air filter or a malfunctioning mass airflow sensor may also disrupt the air-fuel mixture ratio, contributing to the sputtering. Furthermore, some owners note that a pinched exhaust pipe can restrict exhaust flow, resulting in jerking sensations and power loss during acceleration. A dirty throttle body can exacerbate these symptoms, leading to poor engine performance and erratic idling. To mitigate these issues, it is advisable for owners to have the fuel system, ignition components, airflow system, exhaust system, and throttle body inspected and cleaned as necessary. If problems persist, consulting a mechanic or dealership for a thorough diagnosis is recommended.
