Nice video, I used to watch a Guy who says “rev it up Your Engine It’s time for Sxxxx …” but since he Start to be a commercial channel and don’t make sense couple of his comments I unfollowed him, and luckily found your channel. I remember to facing with a Rough Idle and I watched one of your videos and find the problem that I was digging for about 1 or 2 hours. Thanks for your help! Dan, Boston-MA
What a heart-warming video. It's so comforting knowing that, even with all the crap going on everywhere, there are still people like Matt in the world. (And now stylist Vicky has sorted out his hair issue, it seems the channel is going from strength to strength.) Enjoy your new toy! 😃
Thank you for showing us the new toy... ehm... I mean "tool". Love your stuff and glad I subscribe to your paid channel. The content is worth way more than what you charge.
Good presentation. On those 3100 type GM V6 engines, proper ignition wire routing is crucial, especially on the right or rear bank. The rear ones are very close to the hot EGR valve and they are hard to get to. Obviously in this case leaving number 2 out of the factory protective loom is what caused this one to fail. The factory puts that stuff in there for a reason.
PS Matt I made that comment before watching it to all the way to the end that was really big of you to do all that work for free including the parts I've done a few similar things in the last 2 years where people have been out of work but I've made $30,000 each of the last two years more than I've ever made so I passed on some of the kindness as well keep up the good work Buddy
35:00 "it is always magic until it is science" Not sure if Matt came up with that but it is the epic truth 39:12 "it is nothing SHORT of a miracle that...." love it, if engineering stand up comedy was a thing, Matt would own it. Great job, inspiring!
Nice job Matt. i think that might have thrown me a little, that break in the lead was a sneaky one. Nice Picoscope. It's certainly nicer than my Hantek but I don't use a scope enough or have enough skill at diagnostics to justify getting one.
Nice ! You the man Matt ! Nice of you to help them people out. Also that was nice of Robert to give you the Pico. You looked and sounded like a kid on Christmas morning. Lol ! Edit : Matt after watching the whole video, that would of sucked if you had to tell Robert thanks for the Pico that I just fried ! LOL ! Man, that was awesome how you made that woman's day. You right about how it never gets tiring of helping people that are in a bad way.
Years ago I was chasing a radio ignition noise and was not having any luck until I thought about looking at the ignition wiring on a really dark night with the engine running. The problem became obvious. You could see the high voltage leaks easily.
I'm going to have to say that I spotted that right off the bat because of the way the spark plug wire was routed and you had two bad ends I just figured it was that replacement wire became a bad wire though I still would have checked the spark plug like you did cuz that was my other thought process other than that I can tell you're going to love the picoscope
Matt -- you've probably figured it out by now, but when you use a sensor that provides some voltage per physical variable (like 1 Volt per 100 Amp current clamp), in Picoscope you can configure the "probe type" for that exact scaling, and the Picoscope will then label the axes accordingly (in amps in this example) and use the appropriate range. It has a built-in list of probe types, and if yours is not on the list, you can create a custom one. Obviously it's not really doing anything cleverer than just scaling the voltage input, which you can do mentally. But it just makes the scope screen a little clearer.
yes I did see that- I edited out though because it took me so long to figure out and it made the video too choppy when I tried to show it. but even then I still struggled with the trigger. now that I understand how to do the manual trigger I will use the probe menu for sure!
The ground clip on the capacitive pickup is there only to protect your pico scope in cases like that. Where you accidentally hook up on a secondary wire with a leak. So glad that wire didn’t send 60K volts through your equipment!
My dad was a mechanical engineer. He said "the factory never includes things that if eliminated would save money." There is a reason why all the ignition wire are run through insulators and conduit. They didn't put that stuff in there to tidy up the engine bay.
I chased a misfire for days once after replacing plugs. One of the six plugs was a crib death, just wouldn't work. Damn near tore the top end off before finding it by swapping it to a different cylinder, haha.
I had a misfire happen, and it was driving me nuts. I had put a new distributor, new wires and plugs, distributor cap... I put it away in storage, and two years later came back to it, and had misfiring in two cylinders. Was about to buy a new distributor cap, and saw someone give a bad review on the cap I had previously purchased with the EXACT same problem as mine. He recommended a OEM cap, and I bought it, and Voila! Problem solved! Internal manufacturing defect with a cheap cap.
I expect we would have just seen a fairly flat line that had a minimal voltage jump- nothing like a spark pattern. Because the wire was grounded out, you won’t have a voltage spike like you do when it has to jump a plug gap. it would probably have looked like a low voltage square wave I imagine.
I've wanted one of those for YEARS! Couldn't justify it though, and figured I'd use some of the same inexpensive methods and logic you use. But yeah, 1st degree was in repairing digital electronics 2.5 decades ago, and always wanted a scope since then. My wife would have my hide if I bought a toy like that for as much as it costs... They are a wonderful tool though, aren't they?
Yes if you have been here a while you know that when I was considering scopes a few years ago, I was strongly favoring the pico but I found an unbeatable deal on a Vantage Pro and have been happy ever since but even then I still longed for the picoscope a bit. but agreed - I couldn’t justify the expense. I imagine one day I will just suck it up and get a 4 channel pico and when I do I’ll keep you in mind for this one!
c5diag,well done, and many thanks for that great gift you did.your gift, is going to help us all the rest to learn more......I think for c5diag, is very fair if he won't pay again on the pay channel 🤣🤭🤭 I am hoping, one day, I will have a same gift (pico scope) from my wife. I am sick of this useless gifts that she gives me all the time 😂🤣😂.I don't want any other gifts, only one pico scope......
I thought "Pico" was someone working for you in this one... The way you were talking to him it sounded like Pico was some mechanical sage who was tutoring you...
Now Matt... We don't belittle the hired help... Even if they're here on Bidenomics. Don't make Pico angry. You won't like him when he's angry. He'll have to call in hose A and hose b.
EXACTLY!!!!! it’s intentional. I could fill the channel with basic brake jobs and bolt turning and get a much larger audience but I prefer to stick with high level stuff. smaller audience but better crowd.
Country boys would have turned off the lights and stuck their head under the hood and moved the wires around, I know because I gave a car away one time that backfired ,woulodn't start , quit all the time , That night , the guy I gave it drove by with it purring , spark plug wire was shorting , the worst thing was , I had just paid 80 dollars in the 70s to a tune up place , of course they did not replace wires!
Respect Matt but you should have suspected ignition lead 2 because it was crossing over metal and hot surface. Spotted that straight off the bat bad workmanship.
ummm look at the IGNITION CURVE for Christ sakes. it was not arcing until I moved it. come on man. look at the DATA. Just sad. it wasn’t even touching the valve cover anyway SMH.
@@bartsarton2212 I'm good at diagnostic stuff... but chemistry whooped my butt twice in college. I'm not big on memorization, but wanting to know WHY, and was told on the 2nd course, THIS IS NOT A WHY COURSE! You have to memorize! Gah! I seriously admire some of the crazy chemistry used on youtube! Wish I understood it!
I found general chemistry and quantitative analysis to be entirely math- I don’t recall much memorization- it was entirely math. what kicked my ass was Organic Chemistry. I’ll admit- it’s the only course I had to drop and retake. I expected it to be math like general chem and QA but it’s a whole entirely different thing and by the time I figured it out it was too late lol.
