Why is Engine hard to start and hesitates to speed up after idling sometimes dies?

An engine that is hard to start, hesitates to speed up, and sometimes dies after idling could indicate a fuel delivery issue, such as a clogged fuel filter or failing fuel pump. It may also be related to problems with the ignition system, like worn spark plugs or faulty ignition coils. Additionally, issues with the air intake system, such as a dirty air filter or malfunctioning mass airflow sensor, can affect engine performance. Regular maintenance and diagnostics are essential to identify and resolve these issues.
