Twitching and choking are unpleasant symptoms

Choking, jerking or poor response to pressing the accelerator pedal are situations that can annoy any driver. However, this type of symptom is most often encountered by drivers who have installed an LPG system in their vehicles....

Spark plugs, like ignition cables, should be replaced systematically, preventively, because it is these elements that are responsible for the reliable ignition of the gas-air mixture in the engine.

If not the ignition system, then what?

Jerking the car after switching to gas immediately causes problems with the ignition system in memory, but not only this can cause the car to choke. If caring for the ignition system does not help, the cause should be sought in the gas installation itself. It is worth checking the condition filters of the volatile phase, as well as pipes through which gas is supplied to the nozzles... Clogged filters can cause the car to jerk, if not only when driving on gas.

Only high quality gas installation

LPG installation entails tampering with the original electrical system of the vehicle and thus can cause problems, especially if the change was not very reliable or using cheap plugs and cables. Long work These elements can cause small cracks in the covers and thus easily expose the entire system to dirt and moisture. As a result, the car will bounce, scour, and gasp.

Take care of yourself and check

Vehicles with LPG installations are particularly prone to jerks while driving. This is because they are much more sensitive to any malfunction in the ignition system. The most common problems with the ignition system are frayed and dirty wires, worn plugs or dirt on the coil. The problem usually gets worse during cold and humid seasons, because damaged cables do not react well to moisture and dirt. This is why it is so important to regularly replace wires and spark plugs and check the condition of the coil. Usually, these simple operations help to eliminate the problem with throttling and stopping the car on gas. However, if they did not help, you should pay attention to the quality of the LPG system installed in the car and contact a specialist to inspect it.
