Fuel injectors are a critical part to keep your vehicle running. Without them, you could have to deal with performance problems, or your vehicle might not start or run at all. In some cases, however, the signs of fuel injector problems aren't as obvious as you might think. Therefore, you should learn to look out for these four signs that your car needs new fuel injectors.

1. Your Engine Power is Inconsistent

If you notice that your RPM gauge fluctuates or that your vehicle's engine power doesn't feel as strong or consistent as it once did, dirty fuel injectors could be to blame. For added engine performance, you can replace them with racing injectors.

2. You Notice a Gas Smell

Do you notice a gas smell when driving your vehicle? If so, the problem should not be ignored. A fuel injector that isn't closing as it should or that leaks could be to blame. This issue can be more than just annoying; it can also be dangerous. Therefore, you need to have your fuel injectors inspected -- and possibly replaced -- by a mechanic immediately.

3. Poor Gas Mileage

There are a lot of things that can cause your vehicle to get poor gas mileage, such as poor driving habits or improper tire pressure. If you have been driving the same as usual and don't notice anything else wrong with your car, you should have your fuel injectors checked out. If you have a fuel injector leak or other issue with your fuel injectors, then having them replaced can help you get better gas mileage and better overall vehicle performance.

4. Unevenness When Your Vehicle is Idling

When your car is idling, it should purr quietly and maintain a rather even idling pace. If your vehicle isn't idling properly, however, it could be because your fuel injectors are allowing uneven amounts of fuel into your engine. This can cause your vehicle to use too much fuel while it is idling and could be a sign of other performance issues to come. Fortunately, replacing your fuel injectors should resolve the problem automatically.

If your car is in need of new fuel injectors, it is probably showing you signs that you might not recognize. Luckily, if you keep your eye out for these four things, you can have this problem remedied as soon as possible. Then, you won't have to worry about poor engine performance or other injector-related problems.
