Next, think about doing some tests. You can use a tool called a code reader to check your car’s computer for any errors related to the ignition or how the engine is running. Don’t ignore the check engine light – if it’s on, you need to do these tests right away.
Lastly, listen to your engine. If it’s making strange noises, it might be time for a tune-up. By keeping on top of these things, you can make sure your Altima keeps running well.
