Chevrolet Trax poor acceleration and idle missing due to corroded coil pack on Chevrolet Trax

Some Chevrolet Trax owners report experiencing poor acceleration and idle issues, which may be attributed to a corroded coil pack. Symptoms of a defective coil pack include engine misfires that lead to decreased performance, a rough idle characterized by engine shaking or vibrating, and the illumination of the Check Engine Light, which may blink. Additionally, owners have noted increased fuel consumption, altered engine sounds, and a noticeable fuel smell. To diagnose the problem, it is recommended to test the coil pack with an ohm meter to check for continuity and ensure it falls within the appropriate ohm values. If a corroded or faulty coil pack is confirmed, replacing it can help restore engine performance and resolve the acceleration and idle concerns.
