Suitable for 4Pcs Fuel Injectors

Fuel nozzle fault performance:

1.Fuel hole is clogging

2.Poor sealing. Poor sealing of the needle valve and the needle valve body, resulting in poor atomization or oil leakage of the injector

3.Has air in the oil circuit

4.Poor oil supply

5.Insufficient spring force of the piston spring or spring break

6.Piston wear, which affects oil supply

How to judge the injector is clogged or damaged?

1.Engine noise is getting bigger, especially in low gear and below 2500 rpm

2.The throttle response is not sensitive, the acceleration is not smooth, and the throttle will have obvious hysteresis.

3.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.

4.Engine fault light is on
