How can I tell if my car is due for a tune up?

You may be able to tell if your car needs a tune-up by checking the check engine light. If it comes on, this could indicate that there are issues with the engine's performance or emissions control system. You should also pay attention to other warning lights such as those indicating a low coolant level, an oil pressure warning, and an oxygen sensor malfunction. Additionally, you can look out for signs of smoke coming from the exhaust, poor fuel economy, and reduced power output.
