Mazda engine hesitates at high speed?

If your Mazda engine hesitates at high speeds, it could be due to several factors, such as a clogged fuel filter, a failing fuel pump, or issues with the ignition system, like worn spark plugs or ignition coils. Additionally, problems with the air intake system, such as a dirty mass airflow sensor, can also cause hesitation. It's advisable to perform a diagnostic check to identify any error codes and address the underlying issue. Regular maintenance can help prevent such problems from occurring.
