The reason I'm asking this is because a dual coil fires BOTH plugs at the same time. If one plug doesn't fire right, the other won't either, even to a point that neither does. Kepp the coils where they are and swap the plugs and wires and see if you have a change. Let me know

SOURCE: 04 Sedona 3.5 cyl #2 misfire replaced coil,back again 5 mos later

How many miles on the plugs and wires? Misfire can be caused by either plugs or wires, after that check the injector for that cylinder. Let me know what u find. Curt

SOURCE: code p2305 ignition coil b

The wire for the secondary on that particular circuit has to be tested If you have a ICM that secondary has to be tested there, If it is controlled from ECM it has to be tested at the ECM, because its a secondary wire it is capable of shorting the ICM or ECM it self, you only listed the year and.no engine size.

I have a 2006 Malibu 2.2 4 coils miss on number 3


You may have a coil failure or spark plug failure on #3. Swap coil and plug of cyl#2 with cyl#3 and see if problem moves to cyl#2. If so, it will be a plug or coil. I wouls recommend changing both

How to fix code P0306 cylinder 6 misfire?


Swap spark plug with cylinder 4. Swap COP (coil over plug) with cylinder 2.
If problem moves to cyl 4, bad spark plug.
If problem moves to cyl 2, bad COP.
If problem remains in cyl 6, suspect valve or piston problem.
Start with compression check

Jeep 3.7 cylenders 2 & 4 not firing


3.7 V6, mileage?

most likely the HV wires bad.

then bad coil pack.

did you check spark directly at the coil pack?

i use 2 known good HV wires to do that and 2 good test spark plugs.

both plugs grounded to engine (shell)

that is how you test any wasted spark coil pack. 3 coil pack.

if that fails the FSM shows, unplugging it and check the coil resistances. if wrong the pack is bad,

keep in mind the res. can read ok and coil be bad ,due to internal insulation break down (internal shorts)

if thats ok. the resistance , make sure the wires are not (primary)

to the coil (the low voltage connnector)

if that is ok, its mostly likely a bad coil, (pray not bad PCM)

if tool-less? start with cheap parts , work to expensive. (guessing)





now wasted spark 101.

if one line opens , both spark plugs die. no spark

the wasted spark is wired in SERIES. ( like Christmas lights)

the magic cuts cost of 6 coil\'s.

so if the HV wires are say, cheap , carbon wire and open

you lose, both spark plugs. use MAG wire and end this issues.

get some nice NGK mag wire or Bosch Mag wires.

you can see i hate carbon wire. for good causes.

(carbon string wire)

mag wires is real wire that is coil spun and is inductive. it

has the correct impedance but is not a resistor its and inductor.

and lasts the longest , and worth every penny.

No spark on 2-3, ecotech


are you sure thers no spark or is it just missing? look at your fuel injectors
check power and grounds at the coils and swap the coils to other cyls and see if the miss folows.

No spark to the plugs


do you have spark at the coil lead or not?
if spark at coil it could be pionts or rotor button or distributer cap.
if no spark at coil it could be a bad coil.

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

How can you test the spark plug coils, what is the resistance specs on spark plugs ignition coil for a jaguar 2000 s type V6. 3.0L


Dear Pablo,
You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.

Dead cylinders 2003 sebring


it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.
