What happens when 3 injectors are stuck open?
Burning excess fuel makes black smoke, and if you were dumping fuel into the cylinders you’d flood out three and substantially reduce the spray from the other three. I doubt seriously if the engine would run with three injectors stuck wide open. Has the engine been overheated recently? How did the mechanic diagnose this as stuck injectors?
What happens if you put too much gasoline in the injector?
Either way, you need to find the cause of the gasoline odor and fix it right away before it becomes a big safety hazard. If the fuel injector is spraying too much fuel into the engine cylinder, this will create a surge in the engine causing your acceleration to be much slower.
How can you tell if a fuel injector is faulty?
The leak often emanates from the fuel injector seal, resulting in the deterioration in the long run. Fuel odor – This goes hand in hand with fuel leakage, but when your gasoline fails to burn due to faulty injector, or even one which is stuck open, the smell of gasoline will be high.
Why are the fuel injectors on my maxima stuck open?
’90 maxima 245,000 miles…over the course of a few days all three rear injectors (1,3,5) are stuck open and dumping fuel…lots of white smoke and fuel smell. Mechanic told me to replace the fuel injectors, that they are bad. I do not believe this since i recently replaced the injectors.
What is a bad fuel injector?
A car that has a bad fuel injector will often have a rough, or choppy, engine idle. A fuel injector is responsible for injecting fuel directly into the engine cylinder where it is burnt during combustion; if this fuel delivery is compromised, a rough engine idle can result.
What causes a fuel injector to misfire?
Another cause of misfiring is a weak fuel injector a condition that is referred to as “lean misfire” and occurs because there is no enough fuel in the combustion chamber. This condition only affects one cylinder including a shorted or open injector, dirty cylinder and fuel injector poor wiring.
Can fuel injectors be repaired?
Clogged injectors can usually be repaired, if you catch the problem quickly. Sometimes a fuel injector is completely clogged because of years of neglect or a lack of regular engine servicing. If this is the case then a refurbished replacement may be the only option.
What is a bad injector?
Engine missing, along with a rough idle, is a common symptom of a bad fuel injector. A bad fuel injector can restrict or stop fuel flow from being injected into an engine cylinder properly, which can negatively impact fuel combustion and affect engine performance, resulting in missing, a rough idle or misfiring.
