Fuel Injection

Cold Start Injectors and Valves

The Cold Start Valve acts as an extra fuel injector, providing the engine with extra fuel when cold. In theory, it works the same way as a choke on a carburetor, intentionally making the engine run rich until it has warmed up to operating temperature. Usually, when a cold start valve starts to go bad or leak, you will notice poor fuel economy and hard starting when the engine is hot.

Fuel Injectors

Fuel injectors deliver fuel into the air stream as it enters the combustion camber. The injectors atomize the fuel under pressure. If your car is running poorly the injector should be checked.
