GREAT Video with a PERFECT example of using the "P"s and the "G"s in a clear cut diagnostic procedure. The GENERAL testing will get you into the correct FUNNEL of where the problem is , then the PINPOINT testing will have you driving down the funnel to the actual cause of the vehicle's problem. Just keep in mind that everyone's diagnostic procedure doesn't have to be the same, whatever seems to work for YOU is always the best plan. I've been known to have students assemble a jigsaw puzzle in the beginning of a training session and as you suspect, not everyone would assemble the puzzle the same exact way. Some might put all of the edge pieces together first and someone else might start with a section of some scenery first, but as long as the puzzle is completed, the task is done. Same with diagnostic procedures, as long as the concern and the "Root Cause" of the concern is found, the diagnostic procedure is Good. I tip my lab Scopes to BOTH Mario Rojas and Brandon Steckler for a GREAT diagnostic session.

That was a fast diagnostics, putting the pieces of the puzzle together to determine the mechanical fault. Very impressive. Great demonstration, thanks.
I am surprised there isn't more disturbance in the intake manifold pressure pulse from a leaking valve. I would have expected a rise in the pressure pulse as well as the lower pull.
Re-watched this and realised I hadn't given it a like, Brandon is such a great educator and knows his stuff, I can tell from just watching without ever having the opportunity to take one of his courses (I live in Western Australia). Great vid, Mario.
I’ve taken a class with Brandon. I hear a lot of the great advice from both technicians in this same video. So much great diagnostic information in one video!
Great video Mario and special guest Brandon. That run through cleared a few things up for me. Would be great to have something like vision down under. Feel like an Aussie holiday guys 😁

Mario, I only started watching your videos about a week ago, awesome videos by the way, I like when you actually do the step by step setup without stopping the videos. From watching the way you use the pulse sensor and describe how to use it, I have learned a lot! I even purchased Cody's sensor yesterday telling him I heard about it from you! This was a great breakdown explanation video and brother I want to thank you for doing it! You rock! Keep the videos coming an i will keep watching! Thank you!!
Great video and instructions and how to do these test can't wait to get a pico and start doing test so I can educate myself on it with what you have taught me with your videos can't wait for the next video
Good lunch time video man . Very informative , will check out Brandon for sure . Got started watching your videos about 1 month ago , so far all of them been good brain food . Keep it up brother .
Hi Mario and Brandon. Watched the video a few times over the past year. At around 19:58 the piston position overlay lined up with the weak intake pull for cylinder 5. The relative compression shows cylinder 2 issue. Concern is interpreting this correctly. Is cylinder 5 intake pull less because of cylinder 2 not producing proper power. Resulting in the crankshaft slowing down and causing cylinder 5 to have less pull on its intake stroke? Thank you. Have a blessed and safe week to you and your families.
Thanks for sharing information you guys are awesome. It can be complicated to understand but with good training diagnosing this type of fault can be much easier and less time consuming
Hearing why there are so much "noise" in the capture was a great help to me. I also enjoyed your chart to identify what the pistons are doing during the event. I haven't had the pleasure of meeting either one of you but I would be proud to spend some time with you guys.
Jack, I appreciate your vote of confidence. I put my shoes on one at a time like yous guys. I enjoy diagnostics so I invest time to learn. It’s as simple as that. I’m no smarter than ANY of yous guys 👍
can someone please explain the diagnosis to me please. around 20:00 mark. RC showed problem in cyl#2, pulse sensor showed weak vacuum during cyl#5 intake pull. how did they come to the conclusion that the issue is on cyl2 intake valve? is the cyl2 intake valve not sealing properly causing the weak pull during cyl#5 intake? is that what he meant by someone possibly misdiagnosing this as a cylinder 5 issue if the RC was not done?
with #2 on power stroke but intake valve is not fully seated, some of that pressure comes out of the intake while #5 is pulling in air, would this be the reason why it's showing "weak intake vacuum pull" on cyl5?
A cylinders that slows down can also cause a lower intake pull to the companion cylinder (5). Was a leak down performed? If the intake valve was leaking during compression for cylinder 2: wouldn’t the intake pressure be higher? Notice the cylinder 2 was leaking during compression, yet the intake pressure was not affected. Mario thank you for sharing.
Question for you guys. I am new to the first look sensor testing. Are you saying when you are putting the puzzle pieces together, the inlet valve of cylinder 2 is leaking the cranking expanding “power stroke” into the inlet manifold? If so why doesn’t the compression from cylinder 2 show a leaking inlet valve before the piston starts dropping?
just want to make sure im understanding correctly when looking at the pulse and overlay. The diagnosis is cylinder 2 letting compression by the intake valve and causing the weak pull on the next intake pull in the firing order (in this case cyl 5)? The reason we are not saying cylinder 5 has an issue is due to already determining that cyl 2 was the problem cylinder by means of the relative compression test. So with that said, without the relative compression it would be real easy to misdiagnose and think cyl 5 is the problem cylinder if you skip relative compression altogether? im starting to get it i think...sorry im a noob and thank you for this great video!
Back in 2016 i bought a nice silver 04 Grand Cherokee Rocky Mountain Edition with the same i6 engine BECAUSE ive seen so many of those motors rocking 300k+ miles.. and for $1600 bought mine running rough with 105k miles (figured that meant AT LEAST another 100k miles of life left). The VERY first thing i did was check compression of each cylinder as i changed the spark plugs since some kid who barely maintained it drove drove it as his daily, but only very short rides for about 18k miles in 3 years. (Carfax had the entire service info) The Jeep was owned by his father previously and it spent most of its life living in snowy Michigan but to my surprise had VERY little rust, so i figured the low miles made up for it.. AND THAT'S WHEN THE PROBLEMS BEGAN... LUCKILLY it was not my daily driver, but i was only able to put 10k miles in 2 years due to the back to back problems keeping off the road.. from a.c compressor, to valve cover gasket, entire front end (after 2 inch lift, new brakes, and new Cooper A/T tires), but the original springs and shocks held up from the life of gentle city driving. THEN the radiator went (smelled it when it happened and was parked, so no overeating), AND both the mechanical and electrical fans all went bad, and i also changed the condenser since transmission cooler was built within that rather than in the radiator (I thought that was weird but the transmission shifted 100% and stayed cool with the new condenser and fluid flush). BUT in all honesty, i would get another older Jeep, and would recommend them to only those mechanically inclined, esp if you want to learn advanced diagnosis, since its one of the least difficult vehicles overall to repair/upgrade when doing it all yourself..
Mario Rojas and Brandon Steckler team up for the buddy diagnostician video of the year.

Tom, thank you..truthfully, I have friends that are physicians/surgeons and have told me the same . The human body has remain unchanged for thousands of years, and there is only two models
so scope did compression, leak down, 3 hook ups vac, volts, amps? just by long crank!!?lot to learn.u make it look easy!! verify with leak down on #2? then valve job? fast diag. cool! gonna watch again good stuff.thanks
This is why I find this class of such high value. I did my best to share these techniques in my other videos, but that can only go so far! My co-worker decided to leave as is lol he wasn't planning on fixing it 😆 I do have other videos showing the set up. But I highly suggest you grab a seat at one of Brandon's classes! Link is in the description, you will not regret it! Check out the suburban video as well to see how I apply these methods that I learned from Brandon 👍 any questions I'll be more than happy to oblige!
having a hard time understanding, at the time the anomaly occured i understand cylinder 2 was in its power stroke and cylinder 5 was in its induction stroke. how could cyl 2 affect cylinder 5? 20:18
i believe its because cylinder 2 intake valve is the problem. as predetermined by the relative compression test. which is why relative compression is so important. it let you know that cylinder 2 was the problem cylinder. When cylinder 2 comes up on compression, that compression is leaking into the manifold of the vehicle through the intake valve. based on the firing order the next cylinder on its intake stoke is cylinder 5, and since compression is entering the intake through cylinder 2, it causes a weak pull for cylinder 5 (the next cylinder in the firing order with an intake pull).
Brandon is such a talented educator, I can't recommend him enough!
