Why get a fuel injector cleaning service?
Fuel injectors can cost a hundred dollars or more a piece, and you may have one for each cylinder. Cleaning them before they are clogged can remove harmful deposits and keep them spraying in top form. After they clog up, replacement is sometimes the only option. The most common form of injector fouling comes from unused gasoline evaporating inside the injector after you turn the car off. Fouled injectors may give no overt symptoms, even while they are cutting your mileage and pumping extra pollution into the air. But when they get bad enough, they can cause hard starting, hesitation, and loss of power. For the best results, a technician will disconnect the engine from its gas supply and feed pressurized solvent directly into the fuel rail in order to flush out the injectors. Failing that, injectors can be removed from the car, their fuel spray patterns tested. Sometimes, nothing works and the injectors must be replaced.
