Once again Bernie demonstrates technique, the use of pressure transducers and the power of the scope. Amazing! Thank you Bernie for taking the time to film and post!
Problem misfires from other shops are always fun. All new coils, plugs and sometimes even injectors….I’ll install a vacuum gauge and know if it’s mechanical or not in 1-2 minutes. Or maybe bring out the amp clamp and scope if I feel adventurous for a cranking compression test. A simple vacuum gauge will show you restricted exhaust or cam timing issues as well. At least give you a direction to go.
Any tech or shop owner that doesnt believe in using this equipment is dead in the water for anything more than very simple diagnostic work. Shop owners should be able to see the value in the purchase. Accurate, quick diagnosis and no bad review from a customer who was sold the wrong parts
where's bernie's genius son thats gonna take over the reigns when he feels like kicking his feet up in mexico having beers instead of working? THIS MUST GO ON
Bernie! Every video I watched from you I learn a lot! Thank you for teaching us to analyze the data from a higher level! I wished you were my shop foramen when I started doing this job!
Hey there Mr Thompson.. I always look forward to watching you diagnose these cars and trucks of all makes and models. It's sad to see some of these vehicles going from shop to shop to shop.. when they should be calling you first. I know that's not really possible, but your system should be employed across the industry..
Bernie is the master. With Escope misfire detector you can find misfires easily and with the pressure transducers and the rules it makes it so easy. Thanks Bernie for making great equipment. Looking forward for new videos and new lab scope accessories as always.
Saludos Bernie . Gracias por compartir tan importante información y estrategia de diagnóstico . Estoy viendo cada uno de los vídeos , excelente clase . Kike de taller Pit Lane Costa Rica
What's crazy is that those engines are very easy to check cam to cam timing. If you have the special tools, then it is very easy to check crank to cam timing as well.
If the shops would have to pay for all the unnecessary parts they sold to customers they could afford training and proper tools. Obviously, it’s easier to unleash the parts cannon and stick it to the customers.
Hello Bernie, Thanks for the great video's you make. Question, i have the 8 channel scope and can not find the PSI button, is that a new update? Greetings Hans
Thanks for the video Bernie! I’ve been asking if your tool has a known good cam/crank correlation waveform like pico does but I can’t seem to find an answer and it looked like you had one. Anyways I hope you take care of your health!
That's nice. Q: If I have a L4 engine with 2 camshaft sensors on intake and exhaust (VVT engine) and when I see cam crank Waveforms I have a timing issue,,, How Could I know If I have a mechanical timing adjusting or I have a Vvt Solenoid issue?
I’d recommend a trainer named Branden Steckler! He uses the same methods and has even worked with Bernie. He has great in depth analysis and explanation.
is disconnecting the fuel injector not necessary / only done when access is easy? How long is it safe to run the engine (for the cat) before having to worry about it?
Brandon Steckler has a book he wrote about this very topic. Bernie and Brandon network a lot. The book is available on Aeswave. I can't recommend this enough, because so much material about pressure analysis needs to be familiar as we watch Bernie. He moves in real time.
That's Crazy, last car I worked on was a 73 Chevy 305. I have never seen how cars are diagnosed now days... You just blew my mind. Where would be a good place to start if I wanted to learn more about how to do this?
I might be wrong but isn't this a timing chain engine that if you loosen the crank pulley it will jump time? As in it doesn't have a key way in the crank and is held in place by the balancer bolt.
Nice video, great pressure analysis. I can't tell from the video but Im thinking the peak compression was higher than expected also. I would like to see or know what the running peak compression is after the repair, compared to before. Compression and Vacuum are relative.. Low vac = higher compression
i am surprised it caused the low vacuum for only being 34-40 degrees off. would have expected an elevated peak just before the intake opened, or a higher exhaust pressure
Why did fuel trims stay about zero if engine was misfiring, wouldn't that mess o2 readings. Also how maf sensor reading was above normal if exhaust gases take a place of intake air. Where from addditional maf sensor readings come from.
Great diagnosis, Bernie! A pressure transducer and pressure analysis is worth its weight in gold :)
Once again Bernie demonstrates technique, the use of pressure transducers and the power of the scope. Amazing! Thank you Bernie for taking the time to film and post!
That scope is like magic. Its so powerful and fast and combined with a scanner its perfect
Master class Bernie
It goes to show that even if you have the best diagnostic software you still have to use your brain in order to fix the problem. Nice one Bernie!

I just ordered the Escope Elite 8ch from Aeswave! Down side they said it can take two weeks to ship
This guys knowledge is impressive
Bernie preaching pressure transducers! I've got to get to his class!!!
Bernie=legend. When the video started I all ready assumed a vacuum leek. KEEP EM COMING BERNIE!
where's bernie's genius son thats gonna take over the reigns when he feels like kicking his feet up in mexico having beers instead of working? THIS MUST GO ON
Bernie is a national treasure. The Steve Jobs of diagnostics....
Beautiful example of pressure analysis. Looking forward to the follow up. Thanks Bernie!

I missed you Bernie. Good to see you back.
scope for the win again....another awesome diagnosis explained clearly...thanks for sharing.

Wow what a great video. I haven't saved a video to watch later in years but this one is a gem.
Bernie, you should have a million subs.! You are a great teacher..!!
Brilliant yet again you are a master
master BERNIE thanks for sharing, this is a very hig level to diagnose a car with misfire, i like your tablet with a lot of tools on it
So nice to see Real Techs at work! ,, Bravo !
Brilliant interpretation of data !
Didn't see usage of the tailpipe pressure transducer wave form. Otherwise, SUPER! Thank you Bernie!
Diagnóstico certero como siempre! Muy bien explicado. Alguien tendremos un esos equipos!
Thanks for sharing Bernie... Cheers.
I miss you Bernie your videos are awesome
Thank you mr Bernie. God bless you.
Great video Bernie i'm learning a lot form the best. thanks for sharing.
Thank you Bernie! I though Air GPS readings were only accurate in engines above 3.5 liters

Nobody wants to expand their knowledge. Mitchell says 90 percent of time it's this or that with said code so throw a part at it.
It's a top shop but they still call you bernie you are top notch thank you again
Hello Bernie,
Thanks for the great video's you make.
Question, i have the 8 channel scope and can not find the PSI button, is that a new update?
Greetings Hans
Bernie does it again
Thanks for the video Bernie! I’ve been asking if your tool has a known good cam/crank correlation waveform like pico does but I can’t seem to find an answer and it looked like you had one. Anyways I hope you take care of your health!
very help full video
That's nice.
Q: If I have a L4 engine with 2 camshaft sensors on intake and exhaust (VVT engine) and when I see cam crank Waveforms I have a timing issue,,,
How Could I know If I have a mechanical timing adjusting or I have a Vvt Solenoid issue?
Thx Mr Thomson
Good work..!
Who could thumbs down this !!! Thanks for mentioning this Mans name Ivan @ PHAD
If you buy his company tool he should offer training with the scope would love to go to something like that the knowledge he has
I’d recommend a trainer named Branden Steckler! He uses the same methods and has even worked with Bernie. He has great in depth analysis and explanation.
is disconnecting the fuel injector not necessary / only done when access is easy? How long is it safe to run the engine (for the cat) before having to worry about it?
Bernie, will you provide a link as to what needs to be done to get the exhaust cam in time? I haven't found anything. Great video!
He post I watch this gentleman is next level trying to get there
Brandon Steckler has a book he wrote about this very topic. Bernie and Brandon network a lot. The book is available on Aeswave. I can't recommend this enough, because so much material about pressure analysis needs to be familiar as we watch Bernie. He moves in real time.

Yes, this is that one.
You make it look so easy Bernie. Great content!
Guys like him should not be able to retire before 80 years of age
Nice video, great pressure analysis. I can't tell from the video but Im thinking the peak compression was higher than expected also. I would like to see or know what the running peak compression is after the repair, compared to before. Compression and Vacuum are relative.. Low vac = higher compression
Can you use a pressure transducer for diesels for mechanical engine failure?
How much would a shop charge for that diagnosis? Great video.
on cylinder one ignition coil, you grounded the coil why you didnt disable the injector ?
Amazing! Thanks again. Talent on loan from god!
i am surprised it caused the low vacuum for only being 34-40 degrees off. would have expected an elevated peak just before the intake opened, or a higher exhaust pressure
I had misfire for 11 degrees off exhaust with fuel trims dtc
thanks very good
Awesome
👍
Another 1
Maybe I'm dumb, but I don't think the solution was mention 🤷♂️
O O O Oreillys auto parts...ahhhhh!
Who changed the timing belt.
Chain
Be nice if we knew how the exhaust timing became off?
What happened to Bernie? He sounds sad or like without energy.
wow
Amazing!!
Thanks very much it's very good
Coloca uma legenda em português, ou então traduzir para o português, ok

Greta diagosis but the repair will cost more than the truck.
Something seems off with Bernie. I think he’s got health problems. Seems like he has no energy in this video compared to the others
Probably completely fed up with google and unmotivated by the crap going on in the world.
What a waste of time , first step is a compression test, then swap coils then check for contaminated fuel
