Compare Lexus fuel injection system repair quotes from specialist garages

Lexus is known for making luxury vehicles designed according to its defining philosophy: "the pursuit of perfection". In the 2023 Auto Trader New Car Awards, it was voted 'Most Reliable Brand' for the fourth time, maintaining its status as a top manufacturer in the UK.

With several cameos in TV shows (notably Breaking Bad, Silent Witness and Modern Family) and mentions in hip-hop songs (Ignition by R. Kelly and Jay-Z's Somewhere in America), this is a brand deeply ingrained in pop culture.

Lexus has also made waves in the world of motorsport, becoming the first manufacturer to enter a production hybrid car - the Rx 400h - in the Nurburgring 24-hour race.

When you accelerate, your car's throttle valve opens, and the fuel injectors spray fuel. How and when this fuel mixes with air depends on what system is used. Petrol engines use an indirect system, where fuel and air mix before entering the combustion chamber, while diesel engines use a direct system, where air and fuel only mix once in the chamber.

Unfortunately, fuel injectors can become clogged over time, in which case you should book a petrol or diesel injector cleaning service or buy a fuel injection cleaning kit.

Signs you may need to have your fuel injectors cleaned include engine misfires, poor fuel economy, rough idling, engine stalls and leaking fuel.

If cleaning the injector system doesn't work, you may need to book a fuel injector repair or fuel injector replacement, depending on the severity of the problem. A fuel injection specialist can offer advice specific to your vehicle.
