Thank you all for tuning in to Super Mario Diagnostics!
Today we have a misfire diag on a 2003 Hummer H2 6.0L. Unfortunately the customer did not approve the job, but the diag process remains the same.

I’m so impressed. Good job my friend. Diagnostics is fire.
It was the plastic inlet
That heater hose broke on me my Chevy Silverado 6.0 I barely touched it also
hi mario ,nice to meet u， cauld I have a further communicaiton with u?
great diagnose
I got 3rd degree burns from that same thing on my left arm
im getting random misfires on all cylinders, ive tried everything cant find whats causing it
Mr Mario in your opinion what suggested training can you recommend to get someone ready for ASE Certs particularly for electrical and engine performance p.s im already a scannerdanner premium member lol so besides that
got to work and smelled coolant. Popped the hood and noticed small drip coming from one of the heater hoses… lol…well you know what happened next lol I just replaced the plastic pipe that turned to puddy with OEM but I am counting the miles to take them off and just run the hose to the metal pipe with worm clamps.
Ahhhhhh I'm working on one of these too. Misfire data showed cyl 5 and cyl 6 on mine
Great video, thanks
Lol you should see the hoses on the newer chevy cruz they are see me but don’t you dare touch me cuss you will get a hot coolant shower
Since you already had the VC off i would have backed off both rockers,no guessing if the valve is fully closed. I still prefer old school for mechanical. Good stuff though, i like your thought process.
Yeah, that coolant line break sucks. We (wrenchers) already know what's gonna come out of most customer's mouths: "It wasn't broke when I gave it to you." Hopefully, you're dealing with one of the more reasonable customers and will get compensated for "inadvertently" finding and fixing that coolant system ticking time bomb.
Yeah but you and Bubba blah blah blah bye-bye When he does great work and he had a job care of us like I just need to start working From Aleskyfinis
I have not done any diagnosis yet besides hookup a $100 scan tool to the OBD 2 port. The 0P300 code came up, along with a bank O2 sensor code. This issue took place today while driving my HUMMER to military training. With 215,000 miles on the engine, should have known something major was going to happen soon.
Thank you so much for this video. I'm having this issue with my 05 HUMMER H-2. It looks like my Hummer will be sitting in the yard for a while until I can come up with the money to diagnose the problem.
Hey Mario great video. There is a better way then to remove the clutch fan. I've been a tech for 20 years and if your looking for conformation on a leaky intake or exhaust valve by way of air leak test, simply remove your rocker arms and the valves will be closed, mind you the piston will move after adding air but you will get the same results as if you were at TDC, it also works great for checking for head gasket failures. Keep up the great videos!! Oh that piston chart you had on your pico, is that something you downloaded? I would like to get one, they sell the charts on aeswave but having it set up on the computer looks way better.
Hey mario…have a question… if u do a ckp /cmp relationship on a v8 …with a cmp only on one bank, can the bank without a cmp still be out of timming….just trying to learn ..thanks in advance
if you boss is angry about that you deserve a better boss.
Hi Mario
Please do some diesel pulse pressure sensor videos, I can't find no info or videos on this
