Why do my fuel injectors keep going bad?
Fuel injectors will fail when debris (water, dirt particles, etc.) or rust find their way into the system and, after time, plug up the nozzle, the armature, or the nozzle needle gets stuck. You should also consider fuel additives designed for stabilizing the fuel in your system.
What triggers fuel injection?
The magnet on top of the plunger is attracted to the solenoid’s magnetic field, opening the valve. When the plunger rises, it opens a valve and the injector sends fuel through the spray tip and into either the intake manifold, just upstream of the intake valve, or directly into the cylinder.
What is the most common cause of injector failure?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
What happens if your fuel injectors are too big?
Bigger injectors on their own will just increase fuel usage, make the engine run rich, which leads to running problems – it won’t tickover, it won’t pull cleanly through the rev range and you’ll risk major damage through ‘bore wash’ – where the fuel literally washes the oil away.
Can you have to big of an injector?
You can only shorten the pulsewidth so much. Injectors being to large can cause idle issues, bad driveability, and bad fuel mileage.
Do better fuel injectors increase horsepower?
First of all, adding larger fuel injectors WILL NOT CREATE EXTRA HORSE POWER! There is a common misconception that the larger the fuel injector, the more power they create. Fuel injectors do not create horsepower, they support horsepower. The larger the flow rate, the more horsepower they are able to support.
How much horsepower do injectors add?
Larger throttle body and injectors Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. Go too large and you can lose power.
Is it expensive to replace fuel injectors?
Depending on the make and model of your car, the average fuel injector replacement cost will run you about $800 to $1,450 for a full replacement. If you have the knowledge to do the replacement yourself, the parts alone are around $600 to $1200, while the labor cost is only about $200 to $250.
Can I replace just 1 fuel injector?
Yes, you can replace just 1 fuel injector.
