Engine Troit - This problem is not so common, but in some cases it can be difficult to diagnose. This phenomenon in the circle of technicians was called "missing". If any cylinder does not work, then the car engine begins to wear out quickly due to several reasons. For example. gasoline that enters a non-functioning cylinder does not burn out, but accumulates on the walls. Then it mixes with engine oil and enters the crankcase. Because of this, the oil gradually "dilutes", its quality deteriorates significantly - and after a certain time, substandard oil enters the working cylinders. As a result, the compression of the internal combustion engine decreases, favorable conditions are created for creating scuffs on pistons, cylinder walls, precision planes and other parts that come into contact with oil. If the serviceability is not corrected, the engine will start to work in a different temperature regime, it will start to overheat.
Why is the engine running? How to diagnose?1. Diagnostics must begin by checking for spark formation. First you need to unscrew the candle and inspect it. With a normal running engine, the color of the electrode and insulator should be slightly brown and light. If there is smoke in the insulator and electrode, then you should be wary, as this is a clear sign that engine oil is being "thrown" or "enriched" with fuel. Because of this, the candle may either not work at all, or work poorly or irregularly (which causes the engine to troit). Causes of soot formation:
- long-term operation of the internal combustion engine in overheating mode or at idle if a candle of the wrong glow number is screwed in;
- low compression in the cylinder;
- check valve defective;
- violations or displacement of valve timing;
- broken operation of injectors;
- oxygen sensor malfunction.
The body of the candle should be white, it should not have black dots or stripes. Their presence indicates damage to the candle and that it needs to be replaced. If a visual inspection does not bring results, then you can check the sparking when scrolling with the starter.2. High-voltage wires - they must be removed and carefully examined. The tip of the wire that goes into the candle must be a solid color.
3. Ignition distributor cover - it must be carefully inspected both inside and out. The engine often trips due to one problem - a breakdown of the cover, which can occur due to too muchhigh voltage generated by high voltage wire or faulty spark plugs.4. Situations are also possible when the engine troit due to the injector. This happens in the following cases:
- any malfunction of the injector;
- use of poor quality fuel or due to the use of some injector cleaners;
- short circuit power supply.
5. If the engine stalls at idle or in gear, the car owner needs to contact a car service as soon as possible. Perhaps this is due to the fact that the high-voltage wires are reversed in places. This is what the master should pay attention to in the first place.

Flashing "check" and troit engine: diagnostics, search for causes and repair
The car is a complex of complex components and mechanisms. No matter how automakers improve production technology and increase reliability, no one is immune from sudden breakdowns. This applies to all car enthusiasts. Both the owner of an expensive foreign car and a supported VAZ may encounter such a malfunction as engine tripping. Well, let's consider why the "check" is flashing on the car and the engine is troit

Despite the huge amount of criticism against the Lada Priora, this is one of the most popular cars that have come off the AvtoVAZ assembly line in recent years. "Priora" is equipped with a fairly successful engine with good dynamics, the interior turned out to be very comfortable. And in the maximum trim levels useful options are offered. But at the same time, from time to time, the car brings minor problems to the owners. One of the most popular malfunctions is the Priora engine troit (16 valves)
