Product Description:How to judge the injector is clogged or damaged?Engine noise is getting bigger, especially in low gear and below 2500 rpmThe throttle response is not sensitive, the acceleration is not smooth, and the throttle will have obvious hysteresis.The idling range is small, especially when starting, the jitter is obvious, and it is not easy to eliminate. The 1st and 2nd gears have a slight lack of cylinder feel.How fuel injectors workThe fuel injector is actually a solenoid valve with a simple working principle. When the solenoid coil is energized, the suction generated by the needle valve is used to suck up the needle valve and open the nozzle hole. Fuel is sprayed out at a high speed between them to form a mist-like, which can help the fuel to burn fully.Feature:1. Increase your throttle response.Save gasoline .2.
