Causes of instability of the RPM counter RPM counter instability can be caused by many reasons, including: 1- A problem with the fuel system: There may be a defect in the fuel pumping to the engine, or there may be contamination in the fuel that affects the engine's performance, which leads to the instability of the RPM counter. 2- Ignition system problem: There may be a defect in the ignition system, such as a problem with the ignition spark plugs or the cables connecting them, which leads to instability of the RPM counter. 3- A problem with the air system: There may be a defect in the air system, such as a leak in the compressed air flowing into the engine, or a contamination in the air filter, which leads to the instability of the RPM counter. 4- Exhaust system problem: There may be a defect in the exhaust system, such as a leak in the exhaust or contamination in the muffler, which leads to instability of the RPM counter. 5- Injection system problem: There may be a defect in the injection system, such as insufficient fuel reaching the engine, or damage to the fuel injector, which leads to instability of the RPM counter. 6- A problem with the sensors: There may be a defect in the sensors responsible for measuring the number of revolutions per minute, which leads to the instability of the RPM counter. 7- Battery problem: There may be a defect in the car battery, which leads to instability of the RPM counter. In general, any defect in the parts responsible for the operation of the engine can cause the RPM counter to become unstable.
