Problem overview

Some Saturn Sky owners report experiencing decreased power upon acceleration, which may be linked to issues with the catalytic converter. These owners have noted that a clogged catalytic converter can lead to sluggish acceleration and poor throttle response, resulting in limited engine performance. Symptoms such as irregular engine running, unusual exhaust odors, poor fuel economy, and the check engine light illuminating have also been reported. Additionally, owners may experience difficulties maintaining consistent speeds and reduced power, indicating potential problems with the converter. It is essential to address these issues promptly, as a clogged catalytic converter can increase exhaust system pressure, leading to further loss of engine power and excessive fuel consumption. If you suspect a catalytic converter issue, it is advisable to have it checked to ensure optimal vehicle performance.
