Mazda MPV poor performance issue after distributor cap and rotor replacement on Mazda MPV

Some Mazda MPV owners report experiencing poor performance issues after replacing the distributor cap and rotor, including a lack of spark, which may indicate problems with the replacement parts or the installation process. Additionally, some owners have noted size discrepancies with the distributors, as there are two different sizes available, and using the incorrect one can lead to performance issues. Faulty or low-quality replacement parts can also result in rough idling or stalling. Furthermore, improper installation of the distributor cap and rotor may contribute to these performance problems, emphasizing the importance of following correct procedures. If issues persist, some owners find it necessary to conduct further diagnostic testing to identify the root cause, including checking spark and fuel delivery. In cases where home troubleshooting fails, seeking assistance from a mechanic or automotive expert is recommended for effective diagnosis and resolution.
