I've always enjoyed your content because you have a great way of passing along your knowledge in a way we can understand. Man I love the way you have your cart set up.
Yeah, I went to him for the first time last month and he's my mechanic for life. I must say he is very knowledgeable and passionate about what he does.
One of the reasons I ask people what they want . Scan a car or diagnose it . Most don´t understand the difference . You , Me and probably a lot of your followers have seen the f...ed up result you get when you base your repairs solely on fault codes . Nicely done and your cart looks handy too .
That's a great diagnosis, and I had no idea that a single misfiring cylinder can set random misfire codes for other cylinders--I learned something new there. You go the full mile on your diagnostics...there are some mechanics (if you want to call them that) that will simply replace whatever the code says is wrong
hi joe....ive been watching for while....and your gettin good!! the pico multiple scanners and a plus work!! your doing alot of hard work thats paying off
Great video Joe. Please don't worry about a glitch here and there, the videos guys like you, Eric and Ivan put out are gold. Thank you for sharing your knowledge and experience with us. That new pico setup is sweet.
Joe, I love your explanation as to how false misfire codes can be triggered! It makes perfect sense yet it never occurred to me. Thank you! Enlightenment always feels good, even in small doses.
i was glad to hear you say that scan data can fool you i had a ford that had misfire showing on #8 but mode 6 data said it was #7 when it was over had a bad injector on 7 and bad coil on #8. also wanted to address something you said in another video that sometimes you think about quitting video please please don't do that i follow several of ya'll but the way you explain works good for me. i am in southeast alabama small shop work by my self you have helped me several times you tell it like it is and your video is straighforward thanks again
Grest job Joe...I loved the capture of that shorted primary brother! Including your scope setup was really awesome to help those learning how to do it correctly. Using that attenuator on the Pico is something I never need to worry about on the Snap-On platform because they're built in, but I think it is critical to mention that because God forbid we smoke an expensive scope. In either case, I really love your video's, I always learn something new and find it fascinating to watch another guy's approach 👍 Diag cart is stellar...definitely my dream someday...sooooo jealous man! 🤣...but you have earned it, so I am happy it went to a tech like you who ACTUALLY NEEDS it and knows how to use it to diagnose vehicles right the first time! Thanks for your time my friend!
I agree w comment about using parts stores for diag - a sure way to go down every rabbit trail. If you don't have a scope but have a scantool you can still test first - swap coils to see if misfire moves. Unplug injectors to see if cylinder drips or not, etc. Great info in all your videos.
Good info Joe. Thanks for continuing even with all the interruptions you preserved and put out a helpful video. Thanks again. You and wife stay well during these crap times Artie. Keep smiling 😀😀😀🇺🇸
Favorite part of this is the “test don’t guess” approach. With the scope you quickly determined the problem with 100% accuracy and didn’t rely on the parts cannon. Nice work.
being as im still new imo to the scope... i gotta remember doing the amp check.. that alone would eliminate time and tell me whats good and isolate the issue(s) fast!! lol idk how ya'll scope users were when you first started with others stating things like different methods are faster but definitely feels like scope users are on a whole different level and others dont get it... i know my co worker doesnt quite understand... i love using the scope... love it!! keeping using my dd as a mule..
I enjoy the knowledge that you try to teach even if your having a hard time getting ot thru to us. Your passionate about what you do and it shows .Thanks!
Maybe someone can shed some light on a diag i did. A shop gets a 2011 e250 long crank and a cam code p0340. So after the spent 3 hrs diaging the end up sending it to another shop and they repeat the process and call me. I show up pull codes (just p0340) scope it and get a cam crank signal at the computer. It looks fine but i dont have a known good cam crank correlation. Right away i noticed the wiring harness was out of place (i mean really out of place) and some connectors had been changed (throttle body to name one). So I called the first shop just to get a little history. The first and second shop neglected to inform me the engine was replaced ( with a used one) and then this started the long crank and cam code (my understanding engine was replaced from a ping noise by flywheel, i have no clue lol). So after research i found both engines are 5.4 both came from a e250 but ones a 2007 (used engine) and 2011 ( van). First I look at alldata and pull part numbers on cam and crank because i had a hard time finding any thing about the relucter wheel it self . None of the part numbers match not even the cam sensor it self (both was a 2 wire analog). So i call my mechine shop (more knowledgeable on this then me I'LL admit willingly) to see if the motors are interchangeable. At this point with no surprise to me they're not. They dont know why but only 08 to 11 5.4L is possible not 07 SMH. I didnt find a known good cam crank to see the difference and i neglected to bring my scope camera. So i tried to find the cam and crank relucter online to see if there was a difference in both motors with no luck. Also i had no luck with a known good 07 and 11 cam crank correlation. Not a lot of people i can rely on other then the youtube community. Believe it or not theirs still alot of shop that dont use scopes and shotgun parts. I told the shop my hr is up my findings is leading me down the road that the relucter might be different. If the shops was up front about the swap that would of saved about 20mins. My hardest time here was finding information. Did i miss anything? does it sound like i made the right call? Im doubting myself because i couldn't see the relucter and find a known good correlation. The shop didnt want to pay me to move forward (they felt i was on the right track and would take it in their hands). I hated i left it that way but my time has to be compensated for. Sometimes i feel maybe i didnt do enough. Im new at the this.
Remember one time I had a 2004 Chevy car and the code read defective abs module ( can't remember the code), pulled my hair out and in the end I found a broken wire to the front left wheel speed sensor. Repaired the wire, car fixed. That the only one time that the scanner was totally wrong. The fun being a tech. Good diagnosis. 🇨🇦
This type of ignition system I’ve learned how to do.. still learning as always. I’m struggling with setting up and testing the ignition when a single coil pack or distributor type ignition system is used.
@@bohawkins5258 It all depends what you are trying to look at. Remember this. With ignition, you can opt to look at primary ignition. Meaning you have for instance a coil with two wires. One positive, which is ignition 12v power. The other is where your lead goes. To the trigger side. (Use attenuator unless your scope does not need it). You can also look at secondary, via clamping a secondary probe around the ignition wire, or with a paddle style probe held tot he top of the ignition coil. Or you can current ramp the coil with a clamp. This would be installing the clamp either around the positive side feeding the coil, or the control side. Either way will work. I know this is a little information, but i hope it helps a bit.
So I take it you put a new coil on? I had a couple go bad on my old 98 F-150 back in the day. When I tuned it up around 90k I put new boots on the coils and new Motorcraft plugs in, what a difference. The Triton engines are finnicky about what plugs are in them, I only used Motorcraft as I didn't want to do the job twice, lol. That PICO is a handy tool for sure. I like how you can do a compression test by hooking an amp clamp on the battery cable.
Thanks for sharing buddy. Im new to scope, @ 6:40 please can you tell me why we have the second and third strikes are straight line then the oscillations starts? Thanks
Thanks for information Question will the pico do both 12 and 24 volt system? Just started a new job working on big rigs to construction equipment to automotive. Thank you again
Hey Joe! Love the content! Keep it up! Quick question. Got a buddy with an 03 GMC Yukon LT. Stereo fuse keeps popping. Only thing aftermarket is a kenwood headunit. Factory Bose AMP in the vehicle. One of the rear speakers sounds blown (makes pops/cracks even when not playing audio). Where do you think I should start in the debug process? I suspect the factory amp is at fault, but it could also be a wire somewhere shorting to ground.
I've always enjoyed your content because you have a great way of passing along your knowledge in a way we can understand. Man I love the way you have your cart set up.
I am hyper-impressed by your knowledge. Wish I had a mechanic like you here, worth every dollar and more!

It all depends on system design. Diagrams are a big help when you are not familiar with a system.
Joe's Auto Electric hooking up the test leads is where I’m struggling. I’ll keep trying to learn it for sure.

got to love a good scope.
I see you got the other four leads installed in your cart. Real nice setup for sure.
Yes, thanks
Nice, love that 8 channel Pico !
Me too!!! Bad ass!
Good Job Joe!!!!!!!!!!!.
Thanks for sharing Joe... Cheers.
You bet
Where is your shop
Nice job Joe. Keep up great work this was excellent advice
Thanks 👍
Thanks for sharing buddy. Im new to scope, @ 6:40 please can you tell me why we have the second and third strikes are straight line then the oscillations starts?
Thanks
This is normal operation on these systems, it is due to the coil already firing once and having energy stored for the remaining strikes
@@JoesAutoElectric Thank you Joe.
The dreaded sympathetic misfire. How many Fords report the misfire on the cylinder that follows the actual misfiring cylinder?!
Thanks for information
Question will the pico do both 12 and 24 volt system?
Just started a new job working on big rigs to construction equipment to automotive. Thank you again
Yes

nice job. thanks for the video

Thanks 👍
I have a friend whose body temperature is always too cold to activate finger tip heat activated lights. They had to change them all out in her house.
Excellent lesson on misfire Joe!!!
