Mazda RX-8 rough idle and loss of power during acceleration from a stop on Mazda RX-8

Some Mazda RX-8 owners report experiencing rough idle issues, often linked to vacuum leaks, spark plug problems, or ignition coil failures. These issues can lead to noticeable performance declines and discomfort while driving. Additionally, some owners report a loss of power during acceleration, which may be caused by compression loss in the engine, resulting in slow acceleration and diminished high-end power. Symptoms such as long cranking times, frequent stalls, and reduced fuel economy may also accompany these issues, indicating deeper mechanical problems. To address these concerns, it is advisable for owners to check for vacuum leaks, inspect spark plugs, and assess the ignition coil condition, as well as conduct a compression test. If these measures do not resolve the problems, consulting a professional mechanic with experience in Mazda RX-8 engines is recommended for accurate diagnosis and repair.
