Solving electronic injection problems is a job for well-qualified professionals. Electronic injection is one of the most crucial and sensitive parts of modern vehicles. It plays a key role in engine performance, fuel economy and reducing emissions.
However, like any complex system, electronic injection can be affected by several factors, which can lead to malfunctions and operational problems. In this article, we will explore the main causes of electronic injection defects and why choose a qualified company, such as Strike Brasil, to do remap does not pose risks to the system.

Common Causes of Electronic Injection Problems
- Dirty Electroinjector: The injection nozzles are responsible for spraying the fuel into the engine. When they become dirty or clogged, the air-fuel mixture is not ideal, leading to performance problems and excessive fuel consumption.
- Candle and Candle Cable: Spark plugs and worn or faulty spark plug wires can result in misfires, impairing fuel burn and increasing emissions.
- Exhaust System Defect: Exhaust system components such as the lambda probe play a crucial role in monitoring and controlling emissions. When these components fail, the electronic injection may not be able to adjust the air-fuel mixture correctly.
- Adulterated Fuel: Fuel quality is vital for the injection system to function properly. Adulterated fuels may contain impurities that harm the components and the efficiency of the electronic injection.
- Poorly Performed Engine Wash: Engine cleaning is important to keep the engine running smoothly. However, if not done properly, water can penetrate sensitive areas of the electronic injection system, causing electrical problems.
- Sensor Failures: Sensors play a vital role in the functioning of electronic injection. Failures often occur due to bad contacts or sensor failures, which can lead to the electronic injection warning light coming on on the dashboard.
10 Signs of Electronic Injection Problems: Identifying and Solving
Firstly, it is good to remember that electronic injection is the brain of your vehicle, responsible for ensuring smooth performance, fuel consumption efficiency and low emissions. When this system has problems, a series of signs may indicate that it is time to seek help from a qualified professional. In this article, we will explore 10 telltale signs of electronic injection problems and explain how to resolve them.
1. Electronic Injection Light On or Flashing
One of the most obvious ways to identify problems with electronic injection is when the electronic injection warning light stays on or flashes continuously on the vehicle dashboard. Although several reasons can trigger this light, a defect in the electronic injection is one of the possible causes. For an accurate diagnosis, the use of advanced diagnostic tools is essential.
2. Irregular idling or car “dying”
An irregular idle speed is a classic sign of electronic injection problems. When the engine does not receive enough fuel consistently, the revolutions per minute (RPM) drops, resulting in an unstable idle. In severe cases, the car may even “die” and require a restart. This is often noticed at light stops, where the vehicle begins to shake due to fluctuations in RPM and eventually stalls.
3. Motor Vibrating
An engine vibrating excessively is another indication of electronic injection problems. When the engine does not receive the appropriate amount of fuel in one or more cylinders, it tries to complete the combustion cycle without success, generating vibrations. This vibration is the engine's attempt to compensate for the lack of fuel.
4. Engine RPM May Suddenly Increase
Problems with electronic injection can result in sudden and uncontrolled engine rotation. This can happen when a fuel injection nozzle is clogged or dirty, leading to excessive injection of fuel into the combustion system. In other words, this imbalance in the air-fuel mixture causes the engine speed to increase significantly, even under constant load.
5. High Consumption or Low Fuel Economy
Problems with electronic injection, such as clogged or leaking injection nozzles, can result in a significant decrease in fuel consumption. fuel economy. This is because the ECU continues to demand fuel from the injection nozzles, even though the fuel does not actually reach the combustion chamber. The less fuel the engine burns, the lower the fuel economy will be.
6. Fuel Leak
If the electronic injection is faulty or damaged, fuel may leak. Instead of reaching the injection nozzles, the fuel leaks from other points, often around the electronic injection body. If you notice signs of gasoline leaking, it is an indication that the electronic injection may need repairs.
7. Fuel Smell
In addition to visible fuel leaks, a smell of gasoline can be an indication that something is wrong with the electronic injection. If gasoline cannot reach the combustion chamber due to a clogged or defective injection nozzle, you will smell fuel. This problem may be related to faults in the fuel line or faulty sensors that order the ECU (Electronic Control Unit) to inject more fuel than necessary.
8. Emission Test Failure
A broken or damaged fuel injection nozzle can cause incomplete fuel burn or leaks, resulting in increased emissions. This problem may cause your vehicle to fail emissions tests. Increased emissions occur when an injection nozzle is leaking or broken, impairing the efficiency of the vehicle's catalytic converter.
9. Combining Multiple Symptoms
Sometimes an electronic fuel injection problem can manifest itself in a number of ways, including engine vibrations, failure, fuel leaks, and a failed emission test. These diverse symptoms may indicate a multifaceted cause of the problem.
10. Ignition Failure
Sometimes, a problem with electronic injection only becomes evident when the car does not start or does not maintain ignition. This is particularly common in car models that are sensitive to changes in the fuel mixture.
How to Solve Electronic Injection Problems?
To solve electronic injection problems, it is essential to seek out a qualified and experienced professional. An accurate diagnosis and proper repairs are essential to ensure your vehicle returns to optimal performance. Therefore, if you notice any of these 10 signs of electronic injection problems, seek help from a trusted workshop for proper maintenance and repair.
Remember that regular maintenance is essential to keep your electronic injection system in excellent working order and avoid serious problems in the future.
What Causes Injector Nozzles to Clog?
Clogging of injection nozzles is often caused by the accumulation of carbon, old fuel and residue. A clogged injection nozzle is one of the problems with electronic injection that can harm the car's performance.
Additives like STK INJECTOR SHIELD® | DIESEL e STK INJECTOR SHIELD® | FLEX They can work as a controller for depositing the use of diesel fuel, gasoline and ethanol. It keeps the injector system clean, acting as an inhibitor of the formation of sludge and residue.
In more severe cases, the ideal is to professionally clean the injection nozzles, as the use of solvents may not be effective in removing more persistent accumulations.
Is it safe to remap?
Reprogramming the ECU is undoubtedly a safe and effective procedure when carried out by qualified professionals, such as those at Strike Brasil. Additionally, the remap of Strike Brasil is carefully designed to optimize engine performance and fuel economy while maintaining all electronic injection safety parameters. In other words, there is no reason to worry about electronic injection malfunctioning when you choose the Strike Brasil for reprogramming.
Another important factor to consider is that the Strike Brasil, in addition to performing remaps with excellence, offers comprehensive support. Therefore, if you find any electronic injection warning lights on after reprogramming, our team is ready to diagnose and resolve the problem.
