Compare Alfa Romeo 147 fuel injection system repair quotes from specialist garages

Alfa Romeo is a quintessentially Italian carmaker known for the style and elegance of its sporty vehicles. In a 2008 episode of Top Gear, Hammond, Clarkson and May set out to prove that you can't be a proper petrolhead until you've owned an Alfa. The brand's iconic status also stretches beyond the small screen, with its cars appearing in a slew of blockbusters, including The Godfather, The Graduate, Octopussy and The Talented Mr Ripley.

At the 2022 Autocar Awards, the Alfa Romeo Giulia Quadrifoglio was named a future classic, earning praise for being "sublime to drive and beautiful to look at" - a statement that perfectly captures the spirit of the brand.

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.
