SOLID repair. you're absolutely correct about taking the car to a auto parts store.... I remember telling someone that my scanner doesnt tell me whats wrong, it just gives me information to be able to diagnose a car. he said hes going to take it to a place that have an expensive scanner that tells you exactly what part is bad.... facepalm. cant help them all.

[@daviderhahon]

Expensive scanner and probably expensive method of resolution. But still with wrong results...

[@jesselyons2002]

Too be honest. You did a really really good job. Also removing the oil to get the rest of the broken guides. I thought most people would have slap a timing kit and not think about where the other parts of the guide went. But you did surpise me and found some of it in the pickup. Extremely good job.

[@Peter-hc4di]

Say hello to your daughter! I´m so glad you are back Mario! Thank you for this one, best wishes from Sweden!

2009 Honda Accord with MAP error code P1129, rough idle and limp mode (won't go past 3,000 rpm). The solution in my case was engine valves adjustment (intake and exhaust valves). Things I have done to the car that failed to solve the above issue, replaced engine oil, new timing chain, replaced VTEC Solenoid module, replaced Variable Valve Timing solenoid, replaced PCV, cleaned throttle body, checked for vacuum leaks.

[@kirkabrahamson1148]

Great to see another of your videos Mario. Love the process. This video really shows the advantage of using a scope and in-cylinder pressure testing as well as the importance of pre and post-repair data collection.

[@brandonsteckler3417]

This engine boast very minute overlap at idle (for smoothness). It is quite normal to see an intake open about 25-30drg ATDC. During full-phase, the intake will shift positive about 30 crankshaft-degrees 👍. So, you are correct, the IVO is occurring later then conventionally however, it’s desirable for this engine . Great work, Mario!

[@SuperMarioDiagnostics]

Great information! Thanks Brandon! Looking forward to seeing you again at Super Saturday! Thanks for swinging by buddy. I got too used to seeing Ivo right before the end of the exhaust stroke 😆

[@brandonsteckler3417]

Always great to see you, my friend. Me and the Trained By Techs will be waitn’ For you, up here in PA👍. Please give your Girls my kindest regards 😊

[@CarsExposed]

Great to see you back mate and new garage, thank you for taking the time for this video and as always you smashed it... cheers 👍

[@Russell_Duncan]

Thanks for sharing that one Mario. I found it very interesting. It might be a while since you last posted but the quality of your videos is worth waiting for. I hope the lady who owns that car knows how lucky she is that her car got to you. I can’t help feeling like a pile of her money could have been wasted if she’d gone elsewhere. Congratulations on the new job, I wish you the best of luck there.

[@ozzstars_cars]

Great job Mario with the diag and repair. The overlay feature of the bad and good waveform is pretty cool!

[@northpostman]

Great video Mario, can't believe the other shop let you go. Tech's like you are a rare breed. Good luck with the new job.

[@fire7765]

I think you did an excellent job explaining everything, you are one of the best mechanic on you tube.

[@roadkill5333]

Hey Mario!! Great to see you back. I hope you'll enjoy the new job, and I hope there were no burned bridges at the last one! Great video, showing a very difficult diagnosis! You had an idea to start with, but with a simple diagnostic test, you suddenly changed your mind, instead of trying to stay focused on your original thought! That shows talent, education, and caring!! And to also find some debris in the oil pan, to help save the client any further possible issues, was right on point! That's more than education, that's common sense at its finest!! Nice video, and thanks for sharing!!

[@VoltageDropDiagnostics]

Man, I’ve been missing these videos! Great job, Mario!

[@SuperMarioDiagnostics]

Thanks brother! Glad you enjoyed it 👍

[@douglasmontgomery6315]

Mario, another home run !. Oh, you preach buddy.....it's what Great, advanced techs live with EVERYDAY.

[@DylanRabier]

Awesome video! Glad you're back 😁 You look happy at the new place. Love the WPS and your explanation. Thanks for sharing Mario 👍

[@brianraglandsr.2349]

Another great Diagnostic video brother, Can't get enough of seeing a smile while working. Its whats its about man!

[@sonofmontezuma3732]

I was wondering where you been ? Good to see you back at making videos

Good stuff Mario, good to see you back Homie 🤙🏼

[@High_Tech_Mountain]

Great video Mario, very thorough Diag/repair. Thanks for sharing. & Welcome back! Looking forward to future videos.

[@GaryP747]

My problem exactly. Thank you! And congratulations on your integrity!

[@PineHollowAutoDiagnostics]

Mario, awesome work and analysis of those in-cylinder pressure waveforms. Simply top-notch! And "last thing we want is a comeback" haha 100% agreed! Taking off the oil pan and cleaning up that clogged pick up strainer was the extra mile for sure... Not many shops would have gone that far! Good to see you at Super Saturday :)

[@SuperMarioDiagnostics]

Thanks Ivan! Man that was fun huh! 😆 thanks for the awesome support bud, thanks for swinging by! See you next time!

[@stef9027]

Amazing diagnostic skills! Keep up the great work!

[@odishoodisho4904]

We miss those videos Mario great as always thanks for sharing your knowledge

[@orville58]

Great job the oil pan was a big surprise great to see you back

[@Mechaniclyfe]

Good diagnosis strategy, never used transducers before so it’s good to see someone showing what information can be retrieved from one. You earned yourself a sub. 👍🏻

[@billyyoder8171]

Thank you Mario. Good job buddy. God Bless you and your family.

[@gregjones8501]

Great video Mario! I think this one made me understand the (squiggly lines) just a lil bit more! I really appreciate you for sharing this one especially because it’s a Honda and I’ve been around these cars forever and never had a definitive way of arriving at timing diagnostics. My wps is on the way! ✊🏾

[@baxrok2.]

Impressive diag Mario. Thanks for sharing!

[@caliautotech21]

Good to have ya back bro! Man I got excited when I saw a Cody’s auto diagnostics shirt and talking about a new shop.. I immediately thought .. dream team? Lol nice video man

[@meorge9359]

Best of luck at the new place Mario!

[@mattgiles4980]

just like to say this is this first of your videos i watched and i like the way you do things. will be watching more

[@johnshuttleworth6879]

Awesome super mario 😎 leading the way forward with in cylinder 😍 I took Brandon’s class and nice to see it in a KZbin presentation

[@rtchrg440]

Fantastic video Mario - great info on reading pressure transducer waveforms! See you at SuperSat.

[@TJ_Actual]

Great job Mario, can’t wait to get my hands on a WPS.

[@nickmayo2974]

Seen a lot of that at my dealer, but never that MAP code. I’ll have to keep that in mind next time I see a 2.4 with these symptoms. Cool diagnostic approach!

[@CvonEssen]

Good stuff explaining the wave forms, I liked how you go through the comparisons to known good.

[@weldingjunkie]

Great video Mario this one was a good one. I really need to get a wps... see you next week. Thanks for sharing. Good luck on new job

[@EXOVCDS]

Nice diag! Congrats on & all the best to you at your new location!

[@kennethmckee4223]

congratulation on new job glad you back

[@luisbaez88]

Good video. I was lost in this one I need more training when it comes to pressure transducer testing

[@wyattoneable]

I just had to drop in and say "Yes" your back. I'll come back and finish the video...

[@jasonc.4683]

Awesome work brother. Another alternative way to check for back pressure. I'll get one of those pretty soon. Theres so many things on the list 🙃🙃🙃

[@jcordero1224]

Awesome! I have the same vehicle with a similar issue. Thank you Mario!

[@martinguitarhd28]

Excellent video and thanks for showing.

[@jgeorges3061]

Mario, Awesome/Brilliant video and info Bravo and thank you for sharing really enjoyable to watch. cheeeeers

[@dannynelson2763]

Great video i was wondering about you cause it been awhile since your last video. That actually looked like a 30 degree advance on the exhaust stroke intake looked about the same look doing the in cylinder pressure check love the pico stuff keep them coming hope the new work place works out.

[@ismarmeskovic]

Nice too see you in action again,you slackin' lately 😀

[@jamesl197999]

Great video need to get myself in cylinder pressure transducer. Good luck with the new job.

This is a great video.. good step by step process 👍

[@jamespower5520]

Good to see your videos again

[@MasterChief-sl9ro]

I found a rag in the air box once. It was under the filter. As they left it in there cleaning the box out. Problem solved. It had been to 2 shops before I found it..

[@kasapis6]

great Diag love it . you did ask if any any one can think of any thing more that can lack power ,i have one that you did not mention ? contaminated fuel only just last we had a car it was a Honda with low it had a very small of diesel fuel in it

[@jimthecarguy]

Nice diagnoses and repair keep up the good work

[@SuperMarioDiagnostics]

Thanks Jim! Glad to see you swinging by bud 👍👍

[@dylankinch2735]

Great video. Show the value of a scope and pressure transducer. This would be a good vid to show the people that think scopes are overated and that u dont need them. Every tech im the modern era should have and be able to use a scope in my opinion. Awesome vid man

[@naushadali95]

Great video.i love your all videos.

[@stephenmarshall5302]

Really liked this one Mario, great path you took with it. You look wel, hope the new shop is good.

Great diagnosis. Very well done. Thanks for video buddy. Notice your shirt change. Lol

[@arthurfricchione8119]

Mario,good luck in your new place of employment. Just watched a similar video put out by Trained by Techs with an 06 Odyssey 3.5 with a similar problem and how they also explained the wave form and came up with the same timing diagnostics. They also initially thought it could be a valve problem but you both came to the same conclusion. Thanks for showing the screenshots on Honda vehicles. I try and capture them as I own two Honda’s.Your daughter is beautiful. Thanks for everything I’m trying to learn all I can. 👍👍👍

[@SuperMarioDiagnostics]

Thank you very much for your support!

[@daviderhahon]

Kindly send me a link to that video. Thanks. Same here, trying to learn all I can.

[@ktcarroll4723]

I’m dealing with one right now doing the same thing. I took out the O2 sensor and drove it same thing checked fuel pressure 50lbs and flow was good. Added oil to it (2 qts low) and it fixed it for a week and now it’s back. It did have a misfire code on 2-3 cylinder but after adding oil that went away and it ran prefect so now let me check further

[@jetskioremor6692]

Great job by a great man👍👍👍awesome video

[@EKHondaMotive]

Hey Mario! Just to be safe, double check the mark you're using on the crank pulley. I know it sounds weird but there are 2 sets of marks on the damper. Good find buddy and good luck on the new place! Glad to see you back! -100

[@SuperMarioDiagnostics]

Correct, thanks for passing along the good advice. Thanks for swinging by!

[@markferraro5250]

great diag SM right to the WPS money shots thanks so much

[@tydempson3932]

I got the same car and I got the code p0341...but on my scanner it also showed me pending codes p1129, p0339???...you think if I knock out that p0341 code the other 1's will go away.

I have a 2008 honda accord was going down the highway about 65 accelerated to 70 it jerked hard vsa light and a yellow triangle with an exclamation point came on and it lost power but the car was stil goingbut eventually died now it just drains my battery cant drive very far could this be my problem or is it the alternator

Congrats bro ... now back to the video

solid diag, same issue im having, but popping a cmp code 341. new chain kit works

[@jackhfletcher]

Where did you learn to use a picoscope and transducer, and to be able to interpret the data? I’ve been working at a shop for a while but I’m embarrassed to say that I don’t know how to diagnose like this. I want to learn to diagnose like you. I would appreciate any advice!

[@SuperMarioDiagnostics]

Check out Dave DeCourcey on KZbin, and automotive test solutions

[@JoelAutomotiveInaction]

nicely done,good job

[@jamessvetlovics4948]

Hey Mario, great video as always I think you try to explain to much detail in some videos, in your relative compression video you did a great job in detail cuz that was all you were focused on, here we were just focused on the techniques you showed dont feel like you have to disprove everything, just focus on what you show, much love

[@SuperMarioDiagnostics]

Mind you, repetition is how i learn. And viewers may not see my other videos. And I'm pretty much thinking out loud lol thanks buddy

[@30kendel]

What would cause the timing to go out of time? Lack of Oil change that extended the timing chain tensioner? Whats the mileage of this vehicle?

[@flatratemaster]

Great one Mario

[@SuperMarioDiagnostics]

Thanks Mike!

[@mikeosborn638]

+thanks so much for your help on my ford f150.Is there any way you can help me find out where I can find those great wiring diagrams you use. Ive looked everywhere for something like that. I have a 2012 ram that was stolen and they cut a bunch of wires.Anyway if there is any way you can help PLEASE let me know...thanks foryour time

Hi Congratulations for your new workplace! What program you using to overlay two waveform on eachother i like it? In Pico can't adjust horizontally Gregory

[@SuperMarioDiagnostics]

Thanks! In Windows 10 there's a program called pressure waveforms overlay. It's free to use

[@richardmccormack5469]

Will this cause my vsa light also to come on

[@abcdefgh9138]

Fantastic video! Thanks, sir. I'd love to hear your thoughts on the Diagun IV. Would you recommend it to other professionals?

[@SuperMarioDiagnostics]

I would actually. Thank you for watching!

[@jamesdean5087]

Thank you Mario. Whenever possible always show us the proper wave forms of your diagnostics/repair because a picture is worth a 1000 words. I do not have access to a waveform library so I do not know which is correct. In my field of digital electronics component manufactures publish ALL their wave forms so we know what to expect and anything that deviates from that is a faulty part. Thanks.

[@ivanguevara2547]

What was the cost for this repair, i am having the same issue on my Ep3 k20

[@wolverineneo101]

my accord 08 v4 gives less fuel , around 350km in full-tank till it reaches the yellow light what can be the reasons for the fuel drain. total 160k km is driven as shown in the speedometer, and the engine oil was leaking or evaporating or going out thru the exhaust i dont know exactly, one guy told me to change the engine itself he said piston rings are letting the vapor out he told to change engine instead of the piston rings due to the labor charge involved, but when topped up some cheap oil now the engine oil doesnt leak. but fuel consumption has gone up. full tank i used to get 450km now i get 350km , PLS ADVICE

[@hypersomrizz]

Thank you 🙏

[@mook9210]

How much does a timing chain service cost.what was the prices tag

[@terminaldiagnostics5576]

Mario nice diag but man the engine must have had chain rattle on start up that customer was lucky keep up the good work from uk

[@SuperMarioDiagnostics]

Surprisingly it didn't 😳

[@tomkohman4620]

Great video! I own an accord with this engine and was wondering what would cause this failure? Did the engine have high mileage? Was there any indication of excessive RPM operation? It appeared the oil was changed regularly based on the clean oil pan. Thanks for any insights. Tom

[@SuperMarioDiagnostics]

Thanks! The car came in with low oil, and chain was stretched. Had about 140k miles on it

[@edwinlomonaco6754]

I'm interested in your setup. The roll cart with the connections pre-installed. Did you buy it that way or build it?

[@SuperMarioDiagnostics]

I made that myself, the plate is a plastic stock to prevent the independent grounds from being shorted to each other

[@saldivar1579]

Can someone plz tell me how to remove speed governor on 2008 honda accord v6!

[@massagequeenofsucculents_156]

I enjoyed your video. Great info. I'm not a tech however, my 2009 Accord 4cyl is experiencing the same symptoms and the tech I went to said I should just buy another car 🤔 Please let me know how much will a job like this cost to repair? I don't want to give up on my car. It's at 199k miles. Thank you so much in advance
