Engine misfiring : How to TEST an IGNITION COIL easily ? (Lack of power, excessive fuel consumption)

Рет қаралды 78,889

Күн бұрын

The engine dashboard light is on on my car. The engine vibrates and has a lack of power.
The diagnostic tool show the trouble code P0304.
It means that there are misfire on the cylinder number 4.
After having tested the charging circuit, I test the ignition coil on the defective cylinder with an ignition coil tester.
I show you how this tool works.
Since the ignition works well, I test the spark plug with a spark plug tester. The spark plug doesn't work.
So I replace it and check that the engine works well.
The dashboard light becomes off and there isn't trouble code anymore.

Can't afford all that equipment. All i was looking for was how to check a coil pack. Your over my head. I'll try another one.

@TheJavaSync 2 ай бұрын

My experience, I plug of 1 coil while the wngine running, if vibratioan more than before it means the coil is good, note don't plug of too high (1cm -1, 5cm is good to go)

I used a spark plug tester( it has a tube just like your tester with no adjustable distance) on my '95 maxima, the spark was yellow, and a channel on youtube said a yellow spark considered weak is an old wives tale. I'm a bit confused. Can timing cause a weak spark? Thanks.

@EnjoyWheels_En 4 ай бұрын

I don't think timing can cause weak spark, but misfire yes.

@renejacques8288 4 ай бұрын

@@EnjoyWheels_En OK. The spark appears to be intermittent by about a half second to a second where I don't see anything then it reappears; any advice? Can the ignition condenser cause a misfire? Thanks a lot for replying.

@EnjoyWheels_En 4 ай бұрын

On old engines, a bad ignition condenser can cause misfire.

@mircanika7770 3 ай бұрын

YES, but do you have so much oil on the original spark plug, in the first place?

@DonziGT230 3 ай бұрын

Because he sprayed a bunch WD-40 into the hole before removing it.

How many cm the right spark 1 or 2 cm ?

@macknumber9 5 ай бұрын

@EnjoyWheels_En so a healthy ignition coil should jump a 2cm gap? I have a 2008 trailblazer with 175k miles...all I ever did was replace spark plugs about 10k miles ago...I don't want to replace any ignition coils that are fine but I would like to replace them if they are weak

If you have no trouble code, there is no need to replace them.

Something that wasn't said; if you have one bad plug, the rest are probably not far behind and they should all be replaced.

It's right, thanks

@deanjagger1190 5 ай бұрын

Shouldn't you replace all the spark plugs so the engine gets the same spark all over???

@EnjoyWheels_En 5 ай бұрын

Yes it's better to replace all the spark plugs at the same time.

How about the coils after 100,000 miles? Replace them to.@@EnjoyWheels_En

If they work well, no need to replace them I think

@denisdenis2034 5 ай бұрын

nice video for the coils but you are wrong the coil is not ground by the bolt which holds it to the valve cover. on the coil there are two connectors, one for voltage and one for grund. The proof is that to test it with a multimeter to check the primary circuit you must connect to the two branches of the coils and for the secondary circuit you must connect to the connector of the coil which receives the voltage and the other wire of the tester connected on the spring which connects to the spark plug. The real problem with Ford coils of this type is that the worst idiot would surely have done better. In 55 years of mechanics I had never seen such a stupid thing. The spring that connects to the spark plug is a very poor conductor. At the exit of the coil to connect the spring it is simply a flat terminal so the spring only touches the connector through the thin sides of the terminal. To the spark plug which tells us that the spring is really completely embedded on the spark plug terminal??? On my F 150 to no longer have to change coils I made a plate where the coils are now held in place. I removed the springs that connect to the spark plug and installed good spark plug wires. At the other end I installed very good NGK spark plug caps which hold really very securely to the spark plug. All you had to do was extend the wires of the coil connectors and that's it. I've never had to replace coils. Thus positioned, the coils no longer suffer from the heat of the engine. Heat is the worst enemy of coils on all engines.
