Honda Civic engine stalls while driving or idling, difficult to restart on Honda Civic

Some Honda Civic owners report experiencing engine stalling while driving or idling, which can be attributed to several common issues. These include a faulty idle air control valve that disrupts the air-fuel mixture during idling, potentially leading to stalling. Additionally, a clogged fuel filter or a faulty fuel pump may hinder proper fuel flow to the engine, resulting in similar stalling problems. Some owners have also noted that a faulty ignition coil can affect the ignition of the fuel-air mixture, causing the engine to stall unexpectedly. Contaminated fuel, such as bad gas or water in the gas tank, has been reported to cause rough engine performance and stalling as well. Furthermore, issues with engine components like worn spark plugs, a malfunctioning MAF sensor, leaking vacuum lines, or faulty injectors can contribute to stalling incidents. It is crucial for owners to address these potential causes promptly to avoid further stalling and ensure their Honda Civic operates smoothly. If the engine light is illuminated or flashing, immediate repair is recommended to prevent more severe issues. The cost of fixing these stalling problems can vary significantly, from as low as $50 for minor repairs to several hundred dollars for more complex issues like fuel pumps or alternators.
