Q & A
What are the three main issues Bruce discusses regarding fuel injectors?
-Bruce discusses failing fuel injectors, clogged fuel injectors, and fuel injectors that are stuck open.
What can cause a fuel injector to become clogged?
-A fuel injector can become clogged due to poor quality fuel, debris in the fuel system, or wear and tear over time.
What are some signs that you have a clogged fuel injector?
-Signs of a clogged fuel injector include lean codes, rough starts, and insufficient fuel to match the air intake, causing too much air and not enough fuel.
What does it mean when your car is running lean?
-Running lean means there is too much air and not enough fuel in the engine, which can be indicated by lean codes.
What are some symptoms of a fuel injector that is stuck open?
-Symptoms of a stuck open fuel injector include fume smells, oily or gassy spark plugs, decreased fuel efficiency, and black smoke coming out of the tailpipe.
How does a stuck open fuel injector affect gas mileage?
-A stuck open fuel injector can lead to decreased gas mileage because it causes the car to use more fuel than necessary, making it less efficient.
What does black smoke from the tailpipe indicate?
-Black smoke from the tailpipe indicates that the engine is running rich, meaning there is too much fuel being injected and not enough air, causing unburned fuel to exit through the tailpipe.
How can running rich damage the catalytic converter?
-Running rich can damage the catalytic converter because the excess fuel and subsequent explosions in the tailpipe generate heat and cause damage, as the fuel is meant to be burned in the combustion chamber.
What are some temporary solutions for a clogged fuel injector?
-Temporary solutions for a clogged fuel injector include using fuel injector cleaners available from auto parts stores.
What is the recommended long-term solution for a clogged fuel injector?
-The recommended long-term solution for a clogged fuel injector is to remove the intake manifold and clean or replace the fuel injector to ensure it functions properly.

In this video, Bruce from Bruce Custom Motors discusses the signs of a failing fuel injector, including clogged or stuck open injectors. He explains the consequences of poor fuel quality and wear and tear leading to clogs in the injector's six small holes. Bruce suggests checking for lean codes, rough starts, and decreased fuel efficiency as indicators of a clogged injector. For stuck open injectors, he mentions symptoms such as rich fuel smell, oily and gassy spark plugs, and black smoke from the tailpipe, which can damage the catalytic converter. He also touches on the use of fuel injector cleaners as a temporary fix but emphasizes the need for more thorough cleaning or replacement for long-term solutions.
𧽠Solutions for Fuel Injector Issues
Bruce continues by offering solutions to fuel injector problems, such as using fuel injector cleaners available at auto parts stores, which can provide some relief. However, for a more effective fix, he recommends removing the intake manifold to clean or replace the injectors, especially if the rubber seals are worn out, causing fuel leakage and lean conditions. Bruce also suggests soaking the injector in acetone to improve efficiency. He advises viewers to be proactive with fuel injector maintenance to prevent more serious and costly engine problems, and to consider this video as a guide to identifying and addressing failing fuel injectors.

what's going on youtube this is bruce
with bruce custom motors bringing you
guys another video
i hope you guys are liking the videos
that i'm putting out if you guys have
any new suggestions of videos please let
me know in the comments make sure you
mash that like button alright guys in
this video i'm going to tell you guys
three things if you have a failing fuel
injector a clogged fuel injector or you
simply have one that's stuck open yes
they can be stuck open as well so watch
this video from beginning to end and
you'll find out exactly how so pretty
much the first thing that i want to talk
about is if you have a clogged fuel
injector so if you look right there i
don't know if you guys can see i'm
trying to zoom in you have like six
little holes right there so what happens
a lot of times if you're running your
car if you put poor fuel in your car
there's any debris in your fuel system
from wherever you've got gas at or just
wear and tear over time you can
generally get these clogged up and the
only sad part about getting these
clogged up is once they're clogged up
you pretty much have to take off the
intake manifold and i did a video on how
to take off the intake manifold if
there's anyone that really wants to
champion taking it off because these
fuel injectors as you can see these
tubes on the intake manifold right here
this fuel injector sits right below
these tubes right here and this is what
shoots the gas into the engine so some
signs that you have a clogged one will
be if your car is giving you some lean
codes any lean codes could lead to you
having a clogged one and what lean
actually means is you have too much air
coming into your car and not enough fuel
to match it so you're getting all of
this air that the turbo or your intake
is bringing in and your fuel injectors
are not shooting enough fuel to match
that air so you're going to end up
getting the lean cold also
rough starts when you try to start your
car in the morning it's going to be
rough starts and the reason why it's
going to be rough starts is because
you're not going to have your system
primed correctly with enough fuel to
start your car so your starts are going
to take a lot longer generally when
you're starting your out it should be
bam bam start not bam bam bam bam start
if you understand what i'm saying so
that's going to be
another indicator that you have a
clogged fuel injector on the flip side
inside this actual fuel injector it's a
solenoid that's powered by this plug
right here so on the flip side if you
have one that's stuck open what's going
to happen is your car is going to run
rich which means you have too much fuel
and not enough air so basically your
computer normally controls how much fuel
is going into your car through your mass
airflow sensor i did a video on that as
well now if the computer can't control
how much fuel and regulate the engine's
ecm to tell this to open up it's going
to be stuck open so signs that you have
one stuck open or that's generally going
bad it's going to be fume smells or
spark plugs that look really really kind
of oily and smell gassy and if you do a
tune-up or you change your spark plugs
and you notice that it looks oily or
gassy those are some indicators that
your fuel injectors the solenoid is
wearing out or there's some fuel sliding
through the solenoid that's going to be
another thing that you want to look out
for when it's stuck open second thing is
if you notice that your gas mileage on
your vehicle is not efficient as it used
to be that can be an indicator that it's
stuck open and it's shooting out way too
much gas or it just needs to be replaced
or maintenance you might want to always
look out for your fuel economy look at
your average miles per gallon and see if
it decreases over time if it decreases
over time this is something that you
might want to look out for as well
all right guys so the third thing that's
going to be black smoke coming out your
tail pipe when you have black smoke
coming out your tailpipe that means that
you're running rich and that means that
you're shooting way too much fuel into
your engine and it's not being burned in
a combustion chamber so all of that
excess fuel is pretty much going out the
tailpipe you know a lot of times when
you see people they have the anti-lag on
their cars they're actually setting up
their cars to
burn the fuel in the tailpipe and that's
why you hear that popping sound on a lot
of exhaust the tune pretty much doesn't
burn all of the fuel so you're burning
and they and they the time and so
you have a lot of backfire and that's
pretty much just fuel
inside the tailpipe so if you're not
tuned for that and you notice that you
have a lot of black smoke you're running
way too rich and when you're running too
rich you definitely can damage your
catalytic converter with all of that
excess gas going through there and the
heat and the explosions from the burning
because it's all meant to happen in the
combustion chamber not the tailpipe so
you can buy a fuel injected cleaner from
autozone from o'reilly's and you know
i've used them before they do help a bit
but ultimately if you really really want
to get it cleaned or you want to get it
fixed you really want to go ahead and
just take off the intake manifold or
have a service to fix a lot of times
even these rubber seals right here can
just wear out and this can cause a
leakage of fuel and cause you to run
lean
you know like i said if that solenoid is
bad that's when you really have to
replace it or you can even soak this in
some acetone or something that can just
kind of you know clean up this right
here to where it can be more efficient
so like i said taking it off you can
deep dive this and clean it and salvage
it because these aren't too cheap at
times you know but if you just wanted to
save money and wants to be better or
proactive i suggest you
put in some fuel injector cleanup before
it's too late before it turns into a
problem are just temporary but
ultimately you want to take this off so
yeah guys i just want to give you guys
this video on signs to look out for for
a failing fuel injector or one is going
out or one is bad i hope this helped
this is a subscriber request thank you
