Fuel Injection Service | Injector Cleaning Perth | JHG

At John Hughes, we offer expert fuel injection services that help your engine run cleaner, smoother, and more efficiently.

If your car feels down on power or is using more fuel than usual, dirty or worn injectors could be to blame. Our technicians use advanced diagnostic tools to inspect and service your fuel system properly, so you can get the most out of your engine.

Why fuel injection servicing matters

Fuel injectors are responsible for delivering fuel to your engine in precise amounts. When they’re dirty, blocked, or worn, it can affect everything from performance and fuel economy to emissions and engine health.

Regular fuel injection maintenance helps keep your system clean and calibrated. It ensures your engine receives the right amount of fuel at the right time, helping you maintain power, reduce running costs, and avoid unexpected issues down the line.

Fuel injection servicing helps:

Restore engine power and responsiveness
Improve fuel efficiency
Reduce harmful exhaust emissions
Prevent engine damage caused by poor fuel delivery
Extend the life of injectors, pumps, and related components

Not sure if your car needs a fuel injection service?

Here are some common signs to look out for (and why they matter).

01

Your engine feels sluggish or underpowered

Blocked or dirty injectors can cause poor fuel delivery, which reduces performance and throttle response.

02

You’re using more fuel than usual

A drop in fuel efficiency often points to injectors not atomising fuel properly or delivering uneven amounts.

03

The engine idles roughly or misfires

Inconsistent fuel delivery can lead to uneven idling, hesitation, or random misfires while driving.

04

You’ve noticed more exhaust smoke

Black or excessive smoke may indicate over-fuelling or poor combustion caused by injector issues.

05

It’s been over 40,000 km since your last service

Most vehicles benefit from fuel injection servicing every 40,000 to 60,000 km, especially if driven in tough conditions or using lower-quality fuel.
