- เผยแพร่เมื่อ 28 ส.ค. 2024
- In the previous video we traced down a really neat problem happening with this Chevy. Voltage leaking through the insulation skewing the O2 readings. At least I thought it was pretty neat. Now it is time to get this baby fixed!

The wire colors won't matter since the repair will last longer than the rest of the truck.
But the comedy when it's Eric that will crawl under it at the junk yard to pull the same part from it to fix another one in a year!
NO one is going to be confused about the wires because they'll never be seen again. The rust bomb is ticking loudly.
Might lose a couple of points at the car show but not too bad.
i was thinking the same thing....LOL
@@sharg0
@@sharg0, not if he saves the wires from this trip. 😆
Are you sure Wilbert's isn't missing a truck?
Lol good one
Hasn't broken in 1/2 like the one there, so not quite ready.
Now, that’s funny.
30 years ago when I had my old van and there were you pick yards near me (all closed down now) last few trips I was pulling parts from vehicle in much better shape than the truck it was going in. Now that I'm older I miss the yards but don't run my vehicles out that far any more before replacing.
I live in southern IL now but in my younger years I worked as an auto tech back in Oswego NY ! Had a truck come in that folded in half like an accordion that was a truck truly done !
I would like to say that that is one of the cleanest part yards that I have seen. Most of the ones around here are mud pits with scrap metal strewn about.
ABSOLUTELY RIGHT 🤙🏻😎
Clean and clear and safe! A credit to the operator. Salvage parts are NOT trash parts.
Truth
You should have seen it 5/6 years ago.
Much nicer now with the gravel.
@@brianmiller-iz6vfyeah it used to be a junk yard
"This'll really confuse someone one day" classic line. So true. Been on the receiving end of something like that.
Yeah hate it when I work on anything and the wires don’t match the wiring diagram. Just worked on a electric furnace and basically had to go through and change a lot of wires around so the elements would get 220 volts. Of course the homeowner didn’t know who messed with it.
The HVAC man replaced the control board in my boiler; I discovered he had installed a "revision 2" board with new features like support for an outdoor temp sensor to tell it how hard to fire. The original wiring harness was missing several wires required for the new features, and a new harness was hundreds of dollars... but a friend had the same boiler, installed incorrectly, failed and removed, sitting in his basement. I de-pinned a fistful of wires out of his harness and put them in mine, each wire labeled on both ends with the color it SHOULD be in that pin position. Hopefully it'll make sense to the next guy.

Making it right; the way it should be!
Good work.

@@rlewis1946 Thanks! I try. 😂
A Wilbert's run!!!! Merry Christmas Eric O., Mrs. O, and Family!
Nothing like a field trip to Wilbert's for a Christmas present from Eric O !
It's amazing how clean alot of those vehicles look but are all rusted out underneath.
Good place for panels & some doors.
That's how they look in PA too. My O6 looked brand new when I junked it in 2019. The frame looked like it was soaked in acid. Sold it to a guy that had a frame from a TX truck he was building up.
@@Wrang15saved something then. Nice.
Love when you take us to Wilberts. What a cool yard, not a mud hole. Won’t be long and that Chevy will be in Willberts fleet.. Another great video and your skill is non surpassing. I still say YOUR THE BEST. Aaron from Canada. The best TH-cam show on .
The added footage for your local "Outdoor Parts Supply" store is always welcome. HAPPY 🎄 holidays 🎁🙂
You are not a used car salesman, you are a really good car mechanic that goes the extra mile to find the problem. SO!!!!!!!!!!!!! please know we believe you on 99% of everything. The one percent might have to do with Ne-ma??? Hope you and your family have a wonderful Christmas and a prosperous new year. Love is what makes the world go around.
Another fine job by the Master (Technician). If we only had more techs like you Eric. If we put joy-sticks on the scan tools we might get more young people into the industry! 😉
Then they would only be playing with their joysticks 🤣
I wanna join the industry but have to be paid cash only
I absolutely despise exhaust manifold leaks...it literally drives me nuts! I have to fix it! Great video Eric!
I'm glad I'm not the only one. Worst sound ever.
Back before fuel injection I never used manifold gaskets only had to squirt a bit of oil down the carby intake for a couple of days & they would carbon up no leak (leaded fuel also helped).
In this case I think HD stands for Heavily Deteriorated or Highly Depreciated.
Eric = South Main Auto Repair Technician (S.M.A.R.T.)
What a great fuel trim diagnostic, covered many bases.
Agree it helps me learn how to read fuel trims and understand why they are like that
A repair and a trip for some used parts wicked! Thanks for taking us along.
Have a great day!
I just love the U PULL IT place !!!! So clean and all the vehicles are off the ground for easy access. And the prices are REASONABLE !!!! Some parts yards are priced like EVERY part is GOLD PLATED !!!! Clean gravel ground to lay on and a list of where the vehicles are !!!! What more could you ask for !!!! And 99% of the time Eric has success !!!! Gotta love that !!!!!!
Great finish Eric .I really enjoy it when you describe what your looking for when graphing on your scan tool.adds an educational aspect to the video .as always thank you!
I recall when 02 sensors started to appear in the 70’s that we learned that a VTVM (vacuum tube volt meter) had to be used to check the sensor outputs. This was before OBD was mature enough to help with reading the parameters. The impedance of the ubiquitous meters of the time just loaded the sensor circuits too much. The latest digital VOM have much higher impedance and now are more useful for troubleshooting without loading the circuit and chasing your tail.
I sure if you un pin the ECM side and the o2 sensor you could measure the resistance and or voltage induced by a salt/dirt/water bridge.
I’m really surprised how much NY just beats the snot out of those trucks..
Great video.
Good conclusion to a great diagnostic. Even got a bonus trip to the salvage yard and a Bonus Footage confirming the EGR leak.
The next guy at Wilbert's will appreciate your hard work in saving this connector.😊
I recently bought my late uncle's truck, and since it had been sitting for a few months, a mouse had chewed through the wires right at the MAF sensor. $160 at the dealer, so a trip to a pull and pay and $5 later, I was in business. Love going to pull and pay junkyards.
Couldn't find the Pig tail or plug but hey de pining always a good option nice Work Eric O 10:08 @South Main Auto Repair LLC
Eric, you and Ivan from Pine Hollow Diagnostics are the best TH-cam channels on the internet.
P.S. Have a great Christmas and New Year. Dave in Guernsey, Channel Islands.
Great fix, Eric, as usual! Best wishes to you and your family for a Merry Christmas!
I love how you worry about everyone’s opinion you know more than 90% of the mechanics in your field much less the armchair mechanics thanks for sharing
I'd bump that up to 95% :-)
Only a fool wouldnt believe Dr O!!! Thanks for all the best content!!! NJ
Well done SMA. As usual you have exceeded all of our expectations with your diagnosis. I hate throwing parts at repairs hoping to fix the problem. Diagnose, assess, repair and validate. Your customers and viewers love you for it. Thanks and Merry Christmas.
Should probably jack up the radiator cap and replace everything under it in the near future. Another great video!
Jack up the radiator and drive another one underneath it.
Judging by the fuel trim #'s after the wiring repair and new O2's you improved the fuel control 1000%. I was always taught to fix exhaust leaks pre O2 before diagnosing any fuel delivery problems. Those manifolds could be an issue along with the EGR plate you mentioned even though the O2's were working after new ones installed. The response time of the O2 signal to your scanner could be slower because of the leak. Regardless, FANTASTIC video Eric. Wishing you, your family and viewer's a MERRY CHRISTMAS..Looking forward to more video's from you bud.
Eric said no emissions testing since it was a 2500 truck. Run it like it is. Who cares if the cel is on in that toilet
@@mph5896 Funny thing was the CEL wasn't even on on that truck. Just the airbag light, and low fuel alarm, from broken gas guage (sending unit/wire problem probably).
Eric suggested in the last video that this truck shouldn't even be on the road due to rot so I don't think it will be long for this world, unless the owner sells it to Illinois for Wes to suffer trying to fix it.
@@Ragnar8504wish people wouldn't drive old Rusty unsafe vehicles
You could say anything about a motor vehicle Eric and I would believe you.
Love watching you work.
A christmas miracle...sma on a lazy friday
Nice work Eric .definitely a rusty truck ,you almost have to be a detective to know what to look for when vehicle are that old.. hope you and Mrs O have a wonderful Christmas holiday…
Needed wire repair and o2 sensors Nice repair Eric O 12:08 @South Main Auto Repair LLC
Merry Christmas Eric, and Mrs.O ! My gal bought me a Present from your merch lineup! It is QUALITY!
Mary barra needs to take a tour of that yard and see how her past models are holding up...
Bingo PAL 😊
Nother perversity hire🤡🌎🤷🏿♂️😩
Pour fuel in jectors cleaner in tank .
Hardly. She worried about tomorrow not yesterday.
The problem would arise when GM products last longer than a few years. They would get less repeat business.
@@christophermatthews6972 yea get screwed by GM...buy another.
Bonus footage! Nice!
I believe ya I believe ya! Another great fix and you're able to tell the customer exactly what it takes to make it perfect!
Merry Christmas Mr. and Mrs. O cherish the time you have together, and Eric Thank You for all the great videos.
For what its worth from a non-mechanic, the best low lint cleaning pad I use are coffee filters. They are super cheap and great at removing grease/grime from an electrical part when using high % isopropyl alcohol. Q-tips tend to leave strands of cotton everywhere, even on a flat and smooth surface, but especially something like the MAF sensor.
Sounds like a good waste of a coffee filter
@@rollenschultz2707make Irish coffee when you're finished. 'Tis the season
Thats a good tip, no pun intended. Thanks*********+
Get the commercial filters if you can, they are much larger, then you have a choice in size. They work great for cleaning glass also.
Name checks out.
She's in pretty good shape for the shape she's in. Merry Christmas team SMA!
Merry Christmas to you and your family.
Merry Christmas, Mr and Mrs O. Many happy returns
"the 'ol Cosby sauce' comment almost caused me to spit out my coffee I laughed so hard. Absolutely brutal
Hope you and your wonderful family had a great Christmas!
Eric, you are a threat to the entire industry! Repair rather than fire the parts cannon! Blasphemy! Good on you! Holliday Cheers!
Enjoy your program, it’s really good entertainment with your sense of humour, and banter with mrs o 2:59
Nice tidy repair Eric.
I'm with you on the wire color change, it's a non-issue, besides you can see the hump where the butt connectors are, so the repair is obvious.
Merry Christmas everyone!🎄🤙
Nice Bonus Footage at the end Eric O 23:54 @South Main Auto Repair LLC
Eric O’…You know how we Love a trip to Wilbert’s! And then an education on O2 Sensors and Fuel Trims!! Great Show!
What a great place, wilberts…we have similar but not this organized. How the hell do you put up with the salt… I run pickups to 10 plus years. At that timeframe nearly zero rust.
Colorado and Texas. Great video..always a pleasure
Hope yourself and Mrs. O and family have a wonderful Merry Christmas
Any trip to Wilburs is a good trip to Wilburs! Merry Christmas Eric and Mrs 0 and family.
That is the cleanest "You Pick It" I have ever seen. The ones around me are hazardous to just walk through.
"The ol' Cosby sauce"
You are killin' me, dude. lol
This was a good video. Thanks for making it. Always enjoy learning something from your channel. Merry Christmas Eric and Mrs. O.
Great job as always, Eric. Thanks for closing on this one.
Trip to the U-pull ...must be Christmas !
We're lucky in Australii, we have some new Chevy thunder, salt free! !
Hi Eric..hope you and mrs.O Have a merry Christmas and a more prosperous new year..
Looking forward to another year of great repairs.. cheer's 🍻🍻🍻🇺🇸🇺🇸🇺🇸
Taking a page from Ivan’s PHAD playbook….. Bonus Footage. Nice move.
A Wilbert’s field trip on Christmas Eve Eve Eve. Early gift to us viewers. Great video. Thanks!
A junkyard full of chevys??? I’ve never heard of that…..😂😂😂😂
Because the people around Avoca have realised most other makes do not last as long as Chevies in the salt.
I thought almost every city of size had one…the local Chevy dealer!!😂😂😂
A leaking manifold will allow air in as well as exhaust out. This air will be read by the O2 sensor as a lean condition, and no matter how much it richens the fuel trims, that lean condition will persist...even though the actual combustion is very rich.
That Scotch Super 88 is the shiz! It's a little pricy, but worth it compared to the other brands. I keep mine hidden in my tool box.
Have to say, as a driveway mechanic like myself....your videos are both informative and entertaining! And as a side note, you rock the Mathews cap...I to am a Mathews fan..."Switchback solo cam"! Keep all the videos coming, I look forward to all of them!
Thanks for the bonus- "Just in case you didn't believe me footage", but you know what..... I'm pretty sure most of use believed you! You are the man, where other shops and dealers being their problems to, for you to solve, when they can't! Why on earth wouldn't we believe you! Hey Eric.... You, Mrs O. And the family, and everyone at South Main Auto, have a Wonderful Joyous Christmas and Great New Year! Later! J Pol.
@SouthMainAutoRepairLLC nice job and Merry Christmas to you and yours and The Shop
Dr O saves another patient well done Happy Holidays to you and your family...
MERRY CHRISTMAS EVE, also a BLESSED MERRY CHRISTMAS, for you and loved ones!!
Hopefully the Holiday season will be safe for all....
Nothing says Merry Christmas like a SMA trip to Wilbert's. Merry Christmas folks.
Another great bit of diagnosis involving high impedance electrical circuits. Bad cable and bad O2 .... impressive results!
Eric, Vanessa, and your respective families - MERRY CHRISTMAS & HAPPY NEW YEAR !!! May 2024 be a healthy and prosperous year for y'all !!!! 😀😺👍💯🌲
That was wild about the pin holes from some ill advised "probing" of the O2 sensor wires, awesome demo!
What a nice and neat junkyard.
That truck is a Christmas miracle, miracle that its still on the road
They should call Mr O`s SMA Garage "Wilberts waiting room" since most of those cars are heading towards Wilberts...
Just wanted to wish you, the lovely and talented Mrs. O and family a nice Christmas. Hope you have a break and enjoy.
Merry Christmas South Main Auto
Merry Christmas to you, Mrs. O. and the whole O. family! Merry Christmas (or which ever holiday you celebrate) to all of my fellow viewers as well!
Nice job, but what else did I expect? I always learn something new watching you do your thing. Thank you, Eric O. To you and your family and friends, *Merry Christmas*
Merry Christmas to the O family.
To be honest, if it was my truck I would have ditched the connector and hard wired it. Nice job as always.
Have Merry Christmas 🎄
The sensitivity of some circuits amazes me... And it's easy to see how this would confuse many!
My guess is the reason why they discontinued using those connectors was either because of a supply issue a quality issue or a reliability issue period. Or sometimes the supplier might have a hard time keeping up with the demand or would jack up the price because of fixing some kind of a quality or some kind of a reliability issue with the connector.
Merry Christmas to Eric and his Fam.
A very Merry Christmas Eric, to you and your family.
Very good, Eric, it's just too bad. The old truck you're staying worth doing anymore too. Is all this working you're a damn good job man thank you
We use to have batteries drain down from a film of acid on the top of the batteries. Took a meter & could actually see the voltage touching the plastic. Crazy how fast your rigs rust out there. They started using sodium chloride on some sections of road, bridges & overpasses here in Idaho the last 15 years. B4 that rust was never an issue. Our snowmobile trailers seem to be rusting out way sooner if you don't wash them off after each weekend use.
The last time I had one of these I pulled the air filter and it was just a big mouse Condo. They had chewed through the filter and the sensor was a mess, vehicle sat a lot and the critters had moved in. Cleaned it all up including the sensor and all the codes went away. Now I cut mesh and put it over the air intake when I change the air filter in vehicles that don’t run every day. Thanks for sharing the whole process!
Nice find and good work fixin' it up!! It's always fun to visit the 'pick & save'! ;)
Great vid, and thanx for the bonus footage!
Have a Happy Christmas and a Merry New Year SMAR
By the time it starts acting up again it will be down at Wilberts🤣Cheers Mr O hope you & brood have happy holidays & see you in "24.
Yea!! A trip to the salvage yard!!🙌🏾 😂
Merry Christmas, Eric & Mrs. O!
I would have cleaned the MAF anyway. Also the early Gen 3 motors used the intake manifold gaskets with the green o-ring seals so they are probably leaking. With higher manifold vacuum at idle with the TB closed it will pull more unmetered air past them. The later gaskets with the orange o-ring seals don't have as much problems sealing as they age.
The Rust on these vehicles is incredible.
All I want for Christmas is a Mr. O clone! Hope you have a great Christmas with family and friends!! Thanks for treating customers like they are family not!!
Your knowledge and experience and ways you fix is really good to see watch and learn thanks for your time doing videos 👍😂
Merry Christmas and Hapy New Year to you and your family Eric. Cheers.
