    1,2,3,4, radiator side
    5,6,7,8 firewall side
    Continentals are front-wheel drive

    Actually, the vacuum hose to the PVC valve was 'tired'. It was almost collapsed without the engine running.
    Replaced 2.5 inch section of hose with $1.40 per foot vacuum hose from auto store.
    Reset 'check engine light' by disconnecting ground from battery and pressing brake peddle for one minute. All is working now.
    Nice....

Bad COP Ignition Coil cylinder #6,
causing lean O2 Sensor code on
bank 2, where cyl #6 is

$70.00 at auto parts and 15 minutes to install,
one 10 mm bolt

1.2.3.4. Pass
5,6,7,8, Driver Side

Change both front O2 Sensors if
over 100,000 miles on them

Both do it yourself. Hour total time

Misfire cilinder 6


I would go with the obvious first... #6 c.o.p. (coil over plug),while your there change the plug :) the c.o.p. have a really bad track record.Then go after the lean situation.

Need diagram of where #2 plug is. got a code saying #2 is misfiring and left bank is running lean


This is the diagram for the 4.6 1998 Ford Expedition.( Notice the numbers 1-2-3-4 spark plugs are on the left side if you are facing the front of the vehicle.) Please rate my answer if you were helped.
Thanks

Cylinder misfire spark


how many miles on the odometer, mines 95k.
ah a v6, P0306 is #6 misfiring. 2.5L V6
300 is all 6 misfiring.... oops.
it is. for sure.
misfire is cause by many things, only 3 in physics, but many real world. (compression + spark +fuel rates)
i works this easy, way.
i have a full scan tool not just a code reader (near useless it)
i make sure my V6 (I have an 04) holds closed loop at idle and 2500 rpm. i f not , fix that first.
easy, it is. just look, bingo, Open loop, (out of control)
fueling is out of control.
but, first i do that tune up. in the manual, 60k , 120k, 180k, see?
do that first. , spark plugs dont last foreever nor filters.
then i replace both front 02 sensors at 100k miles. there design life.
V6 has 2 front sensors. (rear can , just sit and be ignored)
if it misfires. now, i toss a coin.
compression or fuel pressure.
i can do both in 30min flat but i toss coin lands on fuel.
i check fuel pressure and its.
60psi, fuel regulator is bad,
20psi, same, or bad pump or bad 12vdc to pump, 8v to pump is bad wiring.
one thing that helps is to find out if the engine is running too rich or too lean.
and if there are cracks in the exhuast near the 02 sensors.
i force the EFI rich and lean watching both 02 sensors in my scan tool
to see if i can force them lean or rich.
on the v6, we can introduce air leaks, to the plenum.
this will cause lean, and the o2 most react to my lean forcing
or its dead.
i can force richer, if i suspect lean or 02 shows lean, by
removing the Fuel pump regulator hose (vac) and plugging hose fast.
this causes the FPreg to go to high pressure. max.
causing RICH>
i watch the 02 and see it go rich, if not the 02 is bad or you have exhaust leaks, or dead cylinder causing the 02 to fib.
you have 2 banks, and both banks are running off 1 MAF
so you can look at both 02 sensors (front) B1S1 and B1S2
and see if both react the same. to my forcing's.

i dont think you have 3 bad cops out 6. no.
if any cylinder misfires on bank one, then bank 1 o2 goes nuts
same with the Bank 2. this can aid troubleshooting having 2 banks.
the MAF can not lie for 1 cyclinder nor one bank
the 02s can lie for each bank,
both are key to diagnosis.
let me give an example say
injector 1 leaks.
causing 301s
v6
246
135 left
this is your lay out.
my guess is its not lost compression (no test guess, mostly useless)
not 2 bad cops one on each side will cause 300s
not one bad cop. as other side would be ok.
not one bad injector.
my guess, is fuel pressure is way off.
but///???
or maf running lean (dirty, spary clean it 12inches away not close)
low fuel pressure
too high fuel pressure.

all comments are for engine with 60k mile service done,
60k, 12ok, etc.

Check for vacuum leaks. if misfiring address the misfires as this will cause O2 sensors to detect more oxygen in the exaust system. Check you MAF sensor and clean if dirty

I have a 2000 lincoln ls 3.9 it has a misfire cly 4. I change spark plugs, coils, injector. and the intake seal. It still misfire cly 4. I also check compression it all same i all cly read 120 psi. it also...


Check the fuel injector..some time they give the same code like misfire..if it is good, than go ahead and check the wiring harness if there is a signal coming from it..if no signal..then follow the wire back to the source to see if there a short or open...good luck

2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

Check engine light flashing runs rough not firing on all cylinder2000 lincoln navigator with large triton engine Hooked up diagnnostic and it said 1. system too lean bank #2 2. Unable to bleed up fuel tank...


you may try your rotor button and distributor cap. and spark plug wires. try your map sensor also they tend to cause a lot of misfiring if they go bad.hope this helps.

2000 lincoln navigator unable to bleed up fuel


I think I would try the easiest thing to fix and then see how much straightened out. The fuel tank vacuum will probably be a gas cap not on tight or defective or a gas vapor line has a hole in it. You may need a smoker to find that leak if the gascap is okay,

Bank 1 should have cylinders 1,2,3,4. Since 3 cylinders that are in the same bank are misfiring it must be lack of fuel or bad spark. The tester said that bank was lean. If the plugs were not firing it would be rich with unburned fuel. The tester also indicated the other fuel tank vacuum bleed problem.

You might try the power connector for the Bank 1 injectors or check the injector wiring for #2,3,and 4 to see if they are getting power.

Remember to clear the diagnostic meter to see if the trouble codes return. Would be interested in the outcome.

2002 Lincoln LS misfire on cylinder 6. Replaced coil with new one from O'Rielys. Still saying misfire on 6. Installed new plugs at 100K. Now has 119K.


A bad coil pack can foul out the spark plugs. I have also been told the computer might need to be reset for around $100. You must use Motorcraft OE plugs for this car to run at its best is what my mechanic told me.

the missfire can be caused faulty leads and spark plugs replace spark plugs and leads reset codes by removing engine fuse for 10 sec road test and check codes if the lean on bank 2 comes back you may have a faulty injector or intake manifold leak try some injector cleaner in the fuel overdose it it wont hurt
