Another common engine issue is rough idling. This can manifest as the engine shaking or running unevenly when it's just sitting there. This could be due to a number of factors, including a dirty air filter, a faulty spark plug, or a vacuum leak. A dirty air filter restricts airflow to the engine, causing it to run poorly. Replacing the air filter is a simple and inexpensive fix. Faulty spark plugs can misfire, leading to rough idling. You should replace your spark plugs at the recommended intervals. Vacuum leaks can also cause rough idling. These leaks occur when air enters the engine that hasn't been measured by the mass airflow sensor. Finding a vacuum leak can be tricky, but you can usually hear a hissing sound. You can also try spraying a flammable liquid, such as carburetor cleaner, around the vacuum lines while the engine is running. If the engine speed changes, you've found the leak.

Then there's the big one: engine failure. This is the worst-case scenario, and it can be caused by a variety of issues, from overheating to oil starvation. Overheating can be caused by a coolant leak, a faulty thermostat, or a malfunctioning water pump. Make sure to keep an eye on your temperature gauge, and if it starts to climb, pull over and check your coolant levels. Oil starvation can occur when the engine doesn't receive enough oil, which can be due to an oil leak or a faulty oil pump. Regular oil changes are crucial for preventing oil starvation. If your engine does fail, it might need a complete rebuild or replacement, which can be expensive. That’s why keeping up with regular maintenance and addressing issues as soon as they arise is so important. So, always remember to keep an eye on your engine, perform regular checks, and address any issues promptly. It can save you a lot of stress in the long run.
