How do I Know if I Have a Clogged Fuel Injector?
There are a few ways to tell whether or not you have bad fuel injectors. These are the most obvious signs that you need to clean your fuel injectors:

Lowered Fuel Economy
If you have a digital meter in your car that displays your current MPG, pay attention to it at least once per ride. If you’re usually traveling the same routes, such as heading to and from work each day, you’ll get a firm understanding of what your MPG should be, both in and out of traffic, on and off of the highway. When you notice that there’s a significant decrease, such as 3-4 less MPG on your average, it could be an indicator of fuel economy problems.

This isn’t exclusive to fuel injector issues. Lower gas mileage can be a result of spark plug misfiring, bad air filters, incorrect tire pressure, and more. You shouldn’t immediately assume that your fuel injectors are the problem, but you also shouldn’t rule it out.

Forcing Your Engine
If you can feel that your engine doesn’t want to start, that you’re having issues every time you hop in the driver’s seat, you could have clogged injectors. Your injectors release a mist of gasoline, and when one or more aren’t firing properly, it gives unbalanced results. You should be able to hop in the car, twist the key, and be on your way with no worry.

Not Firing on All Cylinders
That phrase got its name from this issue; when your cylinders aren’t firing properly, you can hear it. Whether you have 4, 6, or 8 cylinders, you’ll be able to hear it. If you’ve recently opened up your hood and can visibly see gasoline on your spark plugs, you definitely have a clogged fuel injector.
