Your fuel injectors are a crucial part of your Toyota vehicle's fuel system, along with the fuel tank, fuel filters, and fuel pump.
What Fuel Injectors Do
Modern cars, trucks, SUVs, and vans feature fuel injectors. They're a lower-emission, more efficient replacement for the carburetors of old. There's usually one in each cylinder, and they use electronically controlled valves to spray a mist of fuel into the engine.
It all starts when the fuel pump sends gas through fuel lines and to the fuel injectors. The engine control unit (ECU) uses sensors to determine when to tell the injectors to spray their fuel into the combustion chamber.
Even the best fuel injectors can go bad, though. Maybe the nozzles have become clogged or gotten too dirty to function. When that happens, your engine performance will begin to suffer.
How to Spot Failing Fuel Injectors

- A misfiring engine
