How do I fix my car having a rough idle after replacing the alternator
Replacing an alternator can sometimes cause a rough idle due to a loose or disconnected vacuum hose. Check that all hoses are properly connected and secure. If the problem persists, it could be an issue with the throttle position sensor, idle air control valve, or fuel injectors. Inspect these components for any signs of damage or malfunction.
Additionally, if the alternator you replaced is not compatible with your vehicle, it can lead to improper voltage regulation and cause a rough idle. Ensure that the new alternator matches the specifications of your car's electrical system.
