Why are my RPM low?

Low RPM (revolutions per minute) can be caused by several factors, including engine issues such as fuel delivery problems, ignition system malfunctions, or air intake restrictions. Additionally, a malfunctioning throttle position sensor or vacuum leaks can contribute to low RPM. It's also possible that the vehicle is in a higher gear than appropriate for the current speed. If the problem persists, it's advisable to have a mechanic diagnose the issue.
