Finally...a point and go video...

I have a misfire on cylinder 2 getting trouble code 0302 on my 2008 Frontier 6 cylinder truck. Opening the hood looking towards the back the plug nearest you to your left (passenger) is cylinder 1, then 3 behind it and finally 5. To your right (driver side) you got 2 nearest you, then 4 and 6 right behind. It just happens that cylinder 2 has a broken 10mm bolt securing the ignition coil. Anyone have a left handed drill bit I can borrow?

in the old days we could just touch the coil wire to someones arm and you could tell right away if it was good or bad.

WELL DONE!

i have a 05 300c hemi and it sparks constantly bought some spark plug wires but figured it could be a faulty ignition coil what do yall think it could be im on a budget so im not trynna waste money on something thats still good (& i dont have the check engine light on )

My car is Sonata 2009, American import, engine 24. It has a malfunction. When the rpm reaches 1500 revolutions, the engine shakes, whether it is moving or standing, and results in a weak engine torque.. I went to the technician more than once and he connected it to a fault detector, but to no avail without any result. .. so what is the solution?

I have the same problem with it’s bad coils and wiring harness which I ordered from Amazon (ignition coil and wiring ) I hope my problem will go away I have zip tied it for now until I get the parts

Sounds like dry bearings on either one of your accessories or idler pulleys. Consider the possibility that a bad plug on #2 was causing the coil to overdrive the plug and eventually fail ie replace your plugs also.

Thanks for the video. Very helpful! Do you have to disconnect the negative battery terminal before swapping out the ignition coils? If yes, won't that reset the CEL and then your OBD2 scanner will not show anything?

@screwsnutsandbolts

I didn't remove the negative terminal each time. I just turned off the ignition between each change, so there was no voltage going to the coils.

Just replaced one on a 1988 Iroc, be happy you don't have a distributor cap you have to mess with too.

or just unplug and replug each coil whilst the engine is running and listen for a drop in engine revs. if no drop is heard, you have identified the defective coil.

This fault isolation technique works to determine if it’s your coil or something else (e.g., spark plug) with cylinder #2. The problem will either move with the coil (as in the video) or stay with cylinder #2. So, if you don’t want to replace all the coils and plugs, this can help find the one thing that needs to be replaced. Of course, this assumes a single fault. If both the coil and spark plug are defective, then both cylinder #2 and #4 would be faulty after the switch. This technique is basic debugging 101 and works great for single point failures that can be swapped and monitored. Kudos to the video presenter, but maybe should have been more specific about what he was trying to isolate (ie, not just trying to determine if the coil was bad).

Hello, I wonder if you or someone else could help me. Right now my car´s automatic transmission is having a little jump from first to 2nd gear, it varies depending on speed or rpm as if not getting the right synchronization, could it be that any of these coils ar at fault? (even tho I don´t get eny error codes) Thank you!

@screwsnutsandbolts

3 жыл бұрын

I would say it's more likely to be an issue with your transmission. Have you had the transmission fluid checked recently ?. If the fluid level is too low it could cause hard gear changes. There may be other causes too so it might be worth taking it to a garage to have it checked out.

Hello Can you write the scanner name and model Thank u

@MusahulluXP

I'm no expert either but ignition coils are (to my knowledge) a part that goes on top of the spark plugs and feeds them the power.

@RzVids

Each spark plug has it own ignition coil. Called a “Coil on Plug” system. Spark Plug wires and distributor are not used at all. It’s not built in, but each spark plug uses it’s own coil connected to the engine wiring harness that send the voltage, that is directly controlled by the ECU.

We can see at the very beginning that coil #2 is different from the others (cleaner) maybe it was placed there just to shoot a successful repair video 😂😂

Here is a real mechanic. Either you understand how things work or you don't. Another way to check is to add an insulated skinny jumper wire from the plug up and out of the hole to another plug sitting out where you can watch it fire. This can be useful with intermittent misfires under load or only at certain temps.
