What happens when fuel injectors go bad?
Engine performance is significantly affected when fuel injectors fail. As the engine misfires, the engine can quickly overheat and pre-ignite the fuel mixture. A damaged fuel injector will not only causes issues with driving, but the effects will persist even as the engine idles.
What causes injectors to go bad?
Fuel injectors typically fail due to a buildup of contaminants such as carbon. Carbon build-up can cause a clogged or partially clogged injector, preventing the injector from closing all the way. Fuel injectors can also leak externally as a result of dry, cracked rubber seals, or cracks within the injector itself.

Is it worth replacing fuel injectors?
But when a fuel injector cracks or breaks, replacement is necessary and it can be expensive. Although fuel injectors are individual, they are designed to work as part of a team with the other injectors. So if you’re wondering if you can replace just one injector or all, the answer is almost always to replace them ALL.

What is a faulty fuel injector?
Faulty fuel injectors on late-model cars will make their presence known by causing a cylinder to misfire. This is because on newer fuel-injected systems, the injectors work in sequence, and when the engine misses a dose of fuel, it won’t run smoothly and may suffer damage over time.
