Every driver knows this unpleasant feeling. You step on the gas, and the car, instead of the usual frolic, barely crawls. The engine is running, but there is no thrust, as if an invisible anchor is attached to the back. Sudden loss of power is a symptom that cannot be ignored.
This is not just an annoying little thing. This is a signal that something is wrong with the car, and the problem can be quite serious. There can be many reasons for this behavior, from trivial to requiring complex and expensive repairs.
Fuel system: when the engine is "starving"
, one of the most common causes is problems with fuel supply. The engine needs a fuel mixture of a certain composition to work. If there is not enough fuel, then little energy is generated for movement. It's like trying to run a marathon on an empty stomach.
What could possibly go wrong? A clogged fuel filter that simply does not allow the right amount of gasoline or diesel to pass through. Or a "dying" gas pump that cannot create the necessary pressure in the system. Sometimes injectors are also to blame, which are clogged and poorly sprayed due to poor-quality fuel.
Ignition and intake system: There is no fire and no air
In order for the fuel to burn and provide energy, you need a spark and enough air. If at least one of these components is missing, the engine will not operate normally. The motor starts to "troit", twitch, and, of course, lose power.
The main culprits are here:
- Spark plugs: over time, they wear out, become covered with carbon deposits and give a weak spark.
- Ignition coils: they are responsible for creating high voltage for the candles. Their failure is a common problem.
- Air filter: if it is clogged with dust and dirt, the engine literally has nothing to breathe.
- Mass air flow sensor (DMRV): if he is lying, the control unit receives incorrect data and prepares the wrong mixture.
Checking these elements is the first thing to do when you lose traction.
More serious "diagnoses"
Unfortunately, sometimes the reasons go deeper. For example, a clogged catalyst or a particulate filter. The combustion products cannot exit the system normally, suffocate the engine, and it cannot operate at full capacity. This is also dangerous because it can lead to overheating and damage to the motor itself.
Another unpleasant story is problems with the turbine on supercharged engines. If the turbocharger fails, the engine turns into an ordinary atmospheric engine, only with much worse characteristics. The power drop in this case will be very noticeable. Do not discount the problems with the gearbox, especially with the automatic.
Don't delay your visit to the service
A sudden loss of power is not a case where you can wait until payday. Ignoring the problem can lead to a cascade of other breakdowns and, ultimately, an engine overhaul.
The best thing to do is to go to a trusted car repair shop for diagnosis as soon as possible. Modern equipment allows you to quickly read errors from the control unit and locate the malfunction. It is better to spend a little time and money on diagnostics than to face much more serious expenses later. High-value offers attract experienced users who understand wagering requirements.
