Step 1
Sometimes drivers notice that the car starts to jerk unexpectedly, go jerkily. This problem can manifest itself in almost any mode and under different circumstances. But the reasons for this can be different.
Step 2
Jerks when increasing revs and when driving at high speed
If the car starts to jerk during acceleration, then the reason may be a lack of fuel when increasing the revs. To verify this, you need to check the jets and economizer. It is worth making sure that there is no air leak from the side. Clogged filters can also be the cause, especially if you have a diesel engine. First of all, the mesh on the fuel receiver is clogged. To fix a breakdown, it is worth removing the rubber tube from the filter and blowing it with compressed air. If these actions did not fix the problem, then it will be necessary to remove the fuel tank and rinse it well, and blow the mesh again. In the future, it may be necessary to replace the fine filter.
Step 3
Why does the car jerk at low speed?
If the problem is detected at low speeds, then the operation of the injectors is checked. It is necessary to check if the harness lies directly on the fuel pipe, then the result of this may be chafing. Accordingly, when the wires are touched, the electrical wiring closes, which means that the injectors simply turn off. The way out of the situation can be a complete replacement of the wires in this part.
Step 4
Why does the car jerk when the gas is pressed?
In this case, there can be many reasons: a malfunction of the fuel pump, a breakdown of the fuel filter, a violation of the air supply, a breakdown of the distributor cover. Experts recommend replacing the candles first. If this does not help, then you should continue to look for the malfunction.
