Maintain your fuel injectors, and you’ll upkeep optimal performance. As such a vital component to your engine, you need to know every possible issue that can pop up, and how to properly clean them to ensure there are no repeat mistakes. Here are some of your most frequently asked questions about cleaning your fuel injectors.
Fuel Injectors Clean
Nothing else is needed to do this on your own, though this is assuming you have basic tools on standby in case you encounter any other issues while attending to the fuel injectors. This is the perfect time to run a visual diagnostic on your vehicle and make a shortlist of maintenance tasks you need to complete, so you won’t be cleaning your injectors for no reason.
Should I use a fuel injector cleaner?
In most cases, you’ll see a lot of debates stating that you don’t need an injector cleaner or kit unless you encounter issues. In truth, preventative measures can offset 99% of all issues, so tending to this on a routine basis is strongly suggested.
You can expect to do a deep cleaning of your fuel injectors once a year, up to 30,000 miles. Anything over that and it’s recommended to clean them again.
Do I know if I have clogged fuel injectors?
There are a few ways:
- Lowered fuel Economy
- Forcing Your Engine
- Not firing on all Cylinders
Let’s Go over Them
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.
