When do fuel injectors need to be cleaned?

Fuel injectors clog when deposits build up over time and thousands of miles; when that happens, they don’t deliver the fine mist of gas that provides maximum performance and efficiency. If that happens, you’ll notice a loss of engine performance or lower fuel economy.

Do you need to clean the fuel system?

That’s why some manufacturers, such as Hyundai, Kia and others, recommend adding a fuel system cleaner to your gas tank periodically if you’re not using Top Tier gas on a regular basis.

Are there any problems with the fuel injectors?

Not only has gasoline gotten better since then, but so have the injectors, so problems aren’t as widespread as they used to be.

How do you remove a fuel injector from an engine?

Remove the fuel injectors from the engine. Remove the o-ring from the in-flow (fuel rail) side of the injector. Connect the tubing to the in-flow side of the fuel injector.

What kind of cleaner to use for fuel injectors?

For our purposes, any fuel system cleaner will work. Corvette people love Techron, Mustang fans like Red Line, and Sea Foam is popular around the world. And then there’s Lucas, Gumout, Marvel, etc. All have different cleaning solutions of varying strengths, but any gas-tank-style fuel treatment will work fine at 100% strength.

Can a clogged fuel injector cause a misfire?

In extreme cases, this compromises the fuel injector spray pattern, and the PCM will see this, store a code and display a check engine light. Seriously clogged fuel injectors can cause a misfire or an irregular idle, so clean fuel injectors are essential.

How do you reverse a fuel injector flush?

For a complete reverse flow flush, put the tube on the out-flow end of the injector. Reconnect power to the injector, and it will attempt to fire. Let gravity flow the cleaner through the injector in reverse, removing any deposits that are too big to flow downstream. Slide on new o-rings, and the injector is ready for reinstallation.
