Are you having issues with your car after fuel injection cleaning?
Many people driving old model cars have reported this problem because their fuel injector has worn out.
Even if you never have a problem with your fuel injections, they can become dusty, clogged, or fail and require replacement.
Can a Fuel Injector Cleaner Cause Problems?
A bad fuel injector can cause various issues in your vehicle, including engine vibration and reduced power. Your fuel system and injectors are critical to your car’s overall performance.
Since they are crucial, a damaged fuel injector may be to blame if you have issues with your automobile (such as rough starts, low idling, sluggish performance, or decreased MPG). You may avoid these by cleaning them regularly, so they don’t clog.
You can check for the fuel injector problems below.
- Clogs in the fuel system are still present in the vehicle.
- The fuel pump and the tank lining will cause both damage.
- The sensors are damaged.
A fuel injector can accumulate deposits over time, resulting in blockages and a lack of performance. Many fuel injector cleaners claim to remove build-up from inside the injector, but they may cause issues.
Problems after Fuel Injection Cleaning
Below are some problems users reported after the improper fuel injection cleaning.
Loss of Power
A faulty fuel injector can lead to this problem resulting from the blockage of fuel injections or contaminants, which prevent fuel delivery.
Improper fuel injection will prevent the fuel from spraying on the entire engine or interfere with the frequency you will spray. In any case, your car will not go the way it should or crash.
Diesel Exhaust Fumes
Several diesel car owners reported this problem. Exhaust fumes and general engine malfunction may result from low diesel fuel, which, in turn, shuts down fuel injections.
The engine will vibrate because a malfunctioning fuel injector prevents the associated cylinder from firing. It tries to complete each cycle without gasoline.

Rough Engine Idle
Your vehicle’s RPM dips below the recommended level while idling due to a lack of gasoline or an uneven fuel supply, resulting in a violent idle. The car will stall if the RPM drops too low, and you will have to restart it.
The Engine Light Turns ON
Although this could signify various things, a bad fuel injector may be one of them. When an injector provides less fuel than required (or more in some situations), the engine’s efficiency suffers, and the CEL illuminates.
How to Identify an Improper Pressure Sensor?
An improper fuel injection cleaning can cause issues in the pressure sensor in your car. You can note the factors below to determine if the pressure sensor is malfunctioning.
Gasoline will leak if the fuel injector is damaged or cracked due to damage or aging. Instead of reaching the nozzle, the fuel will seep from the body.
If you look at the fuel injector, you will see gasoline outside or near the fuel rail. The fuel injector seal, which deteriorates over time, is frequently the leak source.
Odor from the Engine
It goes along with a fuel leak, but you will smell gasoline if it does not burn due to a faulty or blocked injector. Your gasoline lines or a defective sensor informing the ECU to inject more fuel than necessary could be the source of the problem.
In any case, you must determine the source of the gasoline odor and correct it as soon as possible before it becomes a significant safety problem.
If the fuel injector sprays too much fuel into the engine cylinder, it will cause a surge in the engine, resulting in substantially slower acceleration. When driving, you will notice that the engine RPM fluctuates significantly under a steady load rather than maintaining constant.
Poor Fuel Economy
If the engine does not obtain the right amount of fuel for combustion, it will put more pressure on the injector to give it more. The car’s fuel economy suffers because of the surplus gasoline that the ECU believes is required but is not.
Emissions Test Fails
Increased emissions might arise from a faulty or leaking fuel injector, which causes an uneven or incomplete fuel burn. As a result, your chances of failing an emissions inspection skyrocket. A fuel injector leak can cause the air/fuel combination to become so rich that the catalytic converter eventually burns up.
Can a Fuel Injector Cleaner Damage the Fuel Pump?
A fuel injector cleaner is unlikely to harm the pump because it lubricates and gently eliminates silt, build-up, and blockages. Many drivers swear through using injector cleaners regularly to increase their car’s engine performance, fuel efficiency, and overall performance.
However, depending on how badly clogged and unclean the injector and fuel system are, you may require more than a single use of a cleaner to remove persistent deposits. To get the most out of a cleaner, regularly apply it to the tank to prevent and expel any accumulated dirt.
What to Use for Cleaning the Fuel Injectors Without Problems?
Choose Chevron Techron Concentrate Plus cleaner for fuel systems if you have a car or another motor vehicle that runs on gasoline. It works on motorbikes, trucks, automobiles, and SUVs. It’s a popular cleanser because of its unique composition, which includes powerful detergents to break up and clean fuel systems, allowing vehicles to run more smoothly, quickly, and efficiently.
This cleaner is popular among drivers because it cleans gasoline injectors, fuel lines, rails, and pumps. This cleanser contains PEA or polyether amine, which eliminates carbon deposits.
Frequently Asked Questions
What happens if you put too much Fuel Injector Cleaner?
Putting too much fuel injector cleaner can damage your gasoline tank. You can also notice a drop in engine power and fuel economy.
Can I put a Fuel Injector Cleaner in a full tank?
While adding the cleaner to a full tank will not harm the engine or the gasoline line, you may reduce the additive’s effectiveness.
How to use fuel injector cleaner the right way?
Here is a perfect video by Helpful Diy that can help you.
If a cleaner is incompatible with the car’s system or is of poor quality, it may not dissolve particulates thoroughly enough, causing difficulties. The average cleaner takes roughly a week to see a difference in engine and drivability. With this informative article, you can diagnose the issue or take precautions.
