What happen if the fuel injector not work properly?
If the injector can’t deliver the dose of fuel called for by the ECU, the fuel-air mix in the combustion chamber will be off, which can lead to misfiring or a sudden drop in acceleration. That’s why it’s so important to keep your car’s fuel injectors clean and free from blockages.
What happens if you have a bad fuel injector?
A faulty fuel injector will cause the corresponding cylinder to not be able to fire. This means that while driving, the engine will vibrate or hiccup after it tries to finish each cycle without fuel. If the engine does not get enough fuel sprayed into due to a clogged injector, then the engine will misfire as you drive.
What causes a fuel injector to leak over the engine?
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.
How often do fuel injectors need to be cleaned?
Fuel injectors do not last forever but you can take steps in preserving their lifespan for as long as possible. Many experts recommend that the fuel injectors be cleaned every 30,000 miles or so. That way, the injectors don’t get clogged and prevent fuel from spraying into the cylinder.
What should I do if my fuel injector cracks?
