Dripping Injector floods engine now won't idle.
Ned Sanders
on a 6 cylinder engine while idling for two minutes. There was also a bottle
of engine flush put in the oil pan. It flooded the engine to the point of
stalling the engine. It was so severe that it won't start. While cranking
it will crank several revolutions before it simply hydrolocks. I notice
raw fuel spitting from the tailpipe when it idles. The center exhaust pipe
was a quarter filled with fuel. I took that apart and drain it. The oil pan
was drained. Two new injectors were put in, making sure it doesn't leak.
The catalytic converter was removed and air dried. With the catalytic
converter on or off the car it still won't idle. It will idle for 15 seconds
with no knocks or pings then stalls even if I press on the gas pedal. It will
easily re-start immediately but stalls after 4 seconds. All the plugs had
spark and all the fuel injectors squirt fine. No smoke is seen coming
from the exhaust. What part of the car is affected by a flooding that
won't let it idle?
Thanks

You did put in new plugs to replace the fouled ones, right? Or if you're
as cheap as I am, cleaned the old ones.

Don't know this car, but to answer your last question, a leaking fuel
pressure regulator diaphragm can cause flooding.
Only way fuel can go around the injectors as far as I know.
Might be better to take it to a pro and get it on a diagnostic machine
instead of taking it apart and putting it together again.

Did you replace the transmission fluid? You clearly should have.

FIXED UPDATE: Thanks for your response. They really help a lot.
Turns out the fuel on the O2 sensors probably dried up the next day or
so (I think) that's what happen.. Now it idles fine To be honest, I was
absolutely stumped when it refuse to idle even when I give it gas. It
was a though a beast's breath was choked when it stalled. This
prompted me to ask the universe for help because I really can't afford
four O2 sensors, or better yet don't have the energy to replace these
rusted-in parts. I really believe in this new age thingy. Well, it paid off.
How this ordeal began. If you want to avoid my mistake, please keep
reading. Initially, one of the injector didn't fire right. I took three
injectors out upon which two slip and fell into the ground. Upon falling
into the pavement a plastic piece on the tip of the injectors cracked in
half. Half asleep and not very bright I put new orings on them then lube
them with some white lithium grease. And then put these broken
injector back into the injector rails. I went to start the engine and two
minute later the motor stalled. This is when the tail pipe is half flooded
with raw fuel. The two new injectors I bought had these plastic pieces,
but they look like unbreakable plastics. Honda fuel injector uses steel
in place of these plastic pieces. Honda design there injectors so they
cannot flood the cylinder chamber no matter how half asleep people
are. I am sticking with a 96+ Civic in the future because it's easier and
quicker to fix. This ordeal is embarrassing to mention but what is more
embarrassing is that the designers can change this design. If they don't
change it in future models, even a brand new injector can flood when
the o-ring binds.
I am linking fuel injector images that are not mine if you want to see the
difference.
