Dual-fuel Jetta idling oil is very stable, while natural gas is unstable, and sometimes it turns off. Clean the throttle. What parts of the solenoid valve have been replaced? The problem has not been solved. There are three main reasons for this problem.

1, the pressure of natural gas supply part is unstable. What you have changed is a few levels of diaphragm. As long as you don't wear it, there is no need to change it. It only plays the role of honey sealing box to drive lever. The key is to look at the spring and spool inside.

Check whether the tertiary pressure is normal.

2. Ignition components

Mainly the spark plug gas spark plug gap is small (about 0.7mm).

Because the fuel is ok, check the exhaust pressure and spark plug for leakage if it is convenient (because natural gas is more sensitive).

3. Air intake part

Check the throttle and idle motor you mentioned.

4, check the pressure reducer cooling (circulating water pipe)
