What would cause my check engine light to come on, car stalled, hard to start and now it sounds like it is missing and flooding itself?

Pressure regulator or fuel injector lines leaking. The check engine light is on?

all stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.

SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.

i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)

if non eof the rings a bell.?
get the car serviced.

this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

wow , no year stated. amazing....
which engine? size and gAS or diesel>?
stalls only hot?
is thermostat good and holding 180F or more???????
why gue$$ ?

Stalls have huge causes.
1: the ISC sticks is but 1 of 50 causes (have list, i pass)
misfire is the other
the EFI Tries very very hard to stop stalls, (opens ISC/IAC 100%)
if it can't. it stalls.
why did it stall, lots of ways.
Misfire from too lean or flooding.
EGR stuck open. is #1 all top DOG for stalls.
EGR can stick open, and when it does, it will stall

no the big questions, not ever answered here ever.....>>
can you save the stall with a fast right foot action.?
easy
tad hard.
impossible.
The answer here, can save tons of hard work.

and is the CEL glow key on, in the dash? Check engine light at key on
then stay out driving, NO< why not scan this car.
do not ever ignore this lamp, scan it or spend eternity fixing car.
buy a scan tool, and learn to use it.
learn how sensors. work and how they read.
learn what closed loop is. (if not in CL hot , fix that now)

if the engine drops closed loop, hot, at idle this means
fueling is out of control and idle is only a victim.
check closed loop status hot engine. and win.


here are all the steps 1 by one on a good engine.

this is just a typical 1.6L 16valve SOHC engine.
MAF based injection, here. any motor with maf , like this..
http://www.fixkick.com/ECU/Authority/A_Full_OBD2_scan.html

engine stalls with any added load, even DRIVE ,
you have engine issues, if it stalls, for any reason.

stalls are complex. (like juggling bowling pins.)
the ECU tries very hard to stop all stalls, and failed
that means the engine power is very very weak.
(misfiring or fuel starvation)

ever give it a full 60k mile tune up this decade? bingo?
(we have a list of 50 causes) forget that
we have 5 tests. that work. (and good fresh fuel)

ill list just 1
key on, is CEL lamp (engine check light) is on?
you start engine, does the lamp go out.? same lamp.
i'd bet not. bingo? that means scan it , with any scan tool.
then post the DTC errors.

in USA some auto stores let you barrow one, Axxx-zoned.

ok 2: check all fuses. really that is #1,....
1: all fuses, both boxes. checked good.
3: tuneup (a full 60k) the one never to miss.
3: CEL indications running.

Sounds like an ignition or timing problem.
Is the check engine light on ?
This engine uses a direct ignition system which means each cylinder has a coil on top of the spark plug. It could be as simple as worn out spark plugs.
If you had said the engine backfired and was hard to start, but no flooding, I would also look at low fuel pressure. But too much fuel causes flooding.
A faulty throttle position sensor could cause all of your symptoms, but it should set a trouble code and turn on the check engine light.

EGR Valve-- could be the problem

if has a fuel odor. it may be the fuel pressure regulator thats bad, it may be flooding out engine. a leaking regulator can cause hard starting, poor fuel economy, stalling, check engine light, gas smell under hood.

Check the fuel system, mainly fuel pump good luck

Check engine light?

Get the fuel injectors checked, the rubber seal may be eroded from sitting. When the seals are dry, it will run rough until the gasoline soaks them which causes them to expand. Although you may not see an error message on the dash, the computer itself may signal a problem in particular. It may be an Oxygen or MAF Sensor too.
