Engine hesitation in a Volvo 740 can be caused by several factors, including a clogged fuel filter, faulty spark plugs, or issues with the ignition system. Additionally, problems with the air intake system, such as a dirty mass airflow sensor or vacuum leaks, can also lead to hesitation.

To replace a faulty speedometer on a 1989 Volvo 740GL, start by disconnecting the car battery for safety. Remove the instrument cluster by unscrewing the screws and gently pulling it out from the dashboard.

Reassemble the cluster, reconnect the battery, and test the new speedometer to ensure it functions correctly.
