How to Adjust Gear Shifting Jerkiness in CNG-converted Vehicles?

[LaAlaina]

If your CNG-converted vehicle experiences jerky gear shifting, you can try the following adjustment methods: 1. Replace the gas injector rail. A faulty gas injector rail may cause the air-fuel mixture concentration to fall below normal levels, naturally resulting in jerky shifting. 2. The jerking could likely be caused by insufficient ignition energy. For instance, if the spark plugs have reached the end of their lifespan, they need to be replaced. If the issue lies with the ignition coils, then the ignition coils should be replaced. 3. You can also try replacing the pressure regulator. 4. It might also be due to a damaged mainboard in the vehicle's ECU, which would require replacing the ECU's mainboard. The above are just some of the more common causes. To determine the exact issue, it's necessary to visit a 4S shop or a professional auto repair shop for a thorough inspection by a technician. Only by identifying the root cause can the problem be properly fixed.
