I really don't care why the coil has failed, I can current ramp but I don't when I know by swappin that it's causing a misfire. Sure I've seen the burned through boots, and I can see one with my eyeballs too. After 35 years of this stuff I'm not real thrilled with scopes unless I need it for a "tough diagnostic". My attitude aside you do nice videos. The only thing you might add is how the coil is controlled. Thanks for an informative video. My poor old Vantage pro sits for weeks sometimes
Wow, what an eye opener. Got this type of issue on my first outback H6 2006, and now it started on my 2011 H6. You wouldn't believe all the crap I heard and the $$$ I shelled. I just realized they were plainly too ignorant to lean to use an oscilloscope. Keep on learning !
Great video, hope to everyone to have the some luck like everyone to see your videos, a great class about how to use the knowledge to see things where the diaagnose machine can't see the fail, best regards from Spain and Happy New Year 2022
Another thing with fords is that they dont have a CKP misfire reference value stored in the computer like dodge and chevy. So if the computer was cleared recently, the computer cant develop a normal crank sensor waveform reference so the computer never sees a missfire.
without the tool, pull the plugs for the injectors one at a time. if the engine does not slow down that is the cylinder. switch 2 coils, if the miss follows the coils it is verified. If the miss stays put check gound and driving circuits.
i would like to have that kind of scanner , it is amazing explanation and quicker way to diagnose and i think there is no other way to test it quick, sometime i have to guess but it is no the correct way, waist money ,time and the worst of the cases lost the client .Thanks for your help and i am really greatfull and i hope one day i will be like you.Thank you very much again and again and again.
What if you are a DIY person and you want to check just using a volt meter, but you don't have a scope, can you tell by the difference in the amps compared to the other 3?
Heres a tip, sometimes its just the bolt that holds the coil on has become corroded, that will also cause high ground resistance but can be fixed with a quick sanding and cleanup of the grounding surface, not going to work every time but beats buying a new coil when you might have a working one, great vid, that tool makes me drool
Actually quite wrong. Totally obvious you don't work on gasoline engines. Pretty much every coil ever has its own dedicated power and ground with one end being controlled by the PCM or ICM. The coil does not even have to be on the engine to fire.
A pc based scan tool.....yeah, some of those are good. You can actually get a lot better DSO than the Versus has for a really good price. Problem is, you are not going to get the specialized automotive database and test setup that goes with tools like the Versus. From what I have read, Owon makes a pretty good 2 channel DSO for about 700 bucks.
my man duane you know your stuff man. I used to use the "power balance" on the autel and it just doesn't pick up a light misfire like the amp clamp. im going to be doing this on a 2003 town car tomorrow the 2nd time has slight misfire.
@beefystik what about using a laptop or tablet pc. i use a laptop with an ALDL cable on my OBD1 GM vehicles and i know that there are cables and software available for obd2. probably i allot less expensive and it does the same thing
How about a 99 Yukon misfire with no code. Have replaced plugs cap & rotor. Plenty of power but after it warms up I get misfire at idle. Only one coil. Hate to throw money at guessing. Any help appreciated. BTW great video! Good explanation and camera.
What about a 97 model 4.6 liter Mercury engine that doesn't have coils on plugs but instead has two coils mounted on the front of the engine? Can those get weak without burning out completely. Mine engine has a misfire I can't figure out.
I just want you to ask if you know how to acquire a data base. or maybe a personal list or how to make with Oscilloscope a Synchronized CKP+CMP signal.
Brake torquing is simply "loading" up the engine without the vehicle moving. All you do is FIRMLY press on the brake, put it in gear and momentarily step on the throttle. BE SURE THE VEHICLE DOESNT MOVE This causes the engine to "load up"
It's frustrating ... mine misfire no codes. Its like a journey to fix it. I suspected that mine was not a coil --- it runs perfect up to 4,500 rpm and when I opened it up, that's where I got the misfire. I was thinking that since I don't run my car so often, it develops water inside the tank. I put a bottle of HEET to dissolves the water, its getting better but still missing a bit at high speed.
HEET is not a fix, it simply displaces water. There are several troubling things in your description of the problem. in particular the 4500 rpm. More detailed info would be needed to offer any advice at all.
@@realfixesrealfast I've done a few preliminary troubleshooting - I drained the fuel (car was not driven a lot), I cleaned and gapped the plugs, I replaced the 02 sensor (all), replaced the map sensor, all 8 cyl firings. Gas was bad before draining it. It happens after I drained the bad fuel. My guess, the water remained in the tank and when I put 5 gallons... the car will run good under no load. When I started to boost, that's where I noticed the power was holding. I keep pouring K-100 (isopropyl) hoping the water bind to the gasoline and hoping to burn it. It gets better but i still noticed if misfire under load. To reach my coil and check the injector is a big task for this car because it's under the plenum if the head (lotus v8 turbo) - I was stalling to open (my last resort) the plenum and reach the coil - wires and test clean the injectors. I checked the fuel pressure, its within the spec. So, I was buying time to diagnose the easy parts but yes/no... it gets better but not quite better yet. Maybe its beyond water in the tank. Thank you for any help and idea.
no 1260 is $1260 whenever you see "$" you are looking at a hexadecimal... it is a value the computer uses to count higher with only two digits... so basically you would need to know what 1 hexadecimal = then calculate that by 1250 and that would be the amount of misses... but seriously just compare to the rest and move on lol

glad it helped, thanks for commenting
You got yourself a very good camera man. Thanks for the video I've learned a lot thanks to you
Hi Duane,
Thanks for the great video. I look forward to seeing future videos
Very good video. Sir you are pure class.
Great lesson ! Thanks !!

Thank you, Happy New Year to you as well
I can't thank you enough for sharing this. Thank you so much ended.

I had a case where the issue was intermittent. It would come and go.
very informative as usual... great video.

The verus is only as good as the person whos interpeting what it tells you
Very interesting !

no .just plain wrong. plastic i heard has very high resistance lol
haywood jablome well of course but not all are just plastic so actually quite right

@turbobuick33 Without a scope you can throw parts at it or check it with a voltmeter

Problem is, you are not going to get the specialized automotive database and test setup that goes with tools like the Versus. From what I have read, Owon makes a pretty good 2 channel DSO for about 700 bucks.
@turbobuick33 He has other vids that tell you. You can swap coils, or replace with a spare till the mis stops. Or, have it scanned for codes.
Imports break down just as much as domestic cars. I work on both in my shop,
and believe me, that flat bed don't discriminate.
Could you use a VOM to measure the coil resistance & come up with the same conclusion??
my man duane you know your stuff man. I used to use the "power balance" on the autel and it just doesn't pick up a light misfire like the amp clamp. im going to be doing this on a 2003 town car tomorrow the 2nd time has slight misfire.
This is a good way to advertize the Versus.

your videos are always great, the problem is knowing how to use the verrus scan tool is a task for itself and I like to know how to use that.
Great video
Snap On Vantage Pro is pretty good and you can pick up a used one for a real resonable price. Just make sure you get the latest software version.
Can you do the same type of test with the fuel injectors? To see if they are weak and not opening all the way like they should?
Haha, go for it.....too rich for my blood.
Thanks, Duane.
I got a question for you Mr Duane...can you use Mode6 on anything other than a Ford, and would it be the same Test ID for any other Make??
Can a d.i.y'er or backyarder buy an inexpensive tool to check out coils thru this means?
@moparmuppet Yeah I ditto the end of what you said id like to hear about what he thinks too.
In my opinion a lot of Snap-on stuff is too much money.....really not worth it. BUT......the test equipment......worth every penny.
PLEASE ADD VIDEOS OF NISSAN PATHFINDERS 2005 OR 2006. THANK YOU..
What is brake torquing and how is it done?

realfixesrealfast so left foot brake and right foot gas?
Thanks so much!

Why you choose ac current option mr. Mariage?
good job
Nice
how I can replace the fuel injector on 03 gmc envoy 4.2 lt 6 cylinder?
why dont you use IDS if its a ford?
What scan tool do you have how much does it cost est. ?
Haha, the Vantage Pro is pretty good and a lot more affordable......nowhere near as nice though.
What model of SnapOn scope is he using?
cursed camera man
can l do that with a ferret 91 lascope
1260 misfires in minute or what ?
no 1260 is $1260 whenever you see "$" you are looking at a hexadecimal... it is a value the computer uses to count higher with only two digits... so basically you would need to know what 1 hexadecimal = then calculate that by 1250 and that would be the amount of misses... but seriously just compare to the rest and move on lol
James Schooley thanks man this is a new info for me. +1
i wish i had 10 thousand bucks to invest in that scan tool.. 0.o
I paid 1600 for it with 2018 version and dock and test leads, good deal?
What if I don't have a scope? Without the scope, how can I test the coil if it is bad?
it is not always tid $53
what scan tool is that
Verus
Pico makes a better scope
I have both, so I win?
he s a liar
Idiot
SUBSTANTIAL Realfixesrealfast
Brilliant video tutorial amazing thank you
