- Come along with Eric O. as he grabs a can of brake parts cleaner and takes a trip up to his brother shop to give him a hand with a Mazda B 3000 with a 3.0 V6 that has a lean code and a misfire. Not the average intake leak but a simple over look! Oooops!

90% of all repairs can be traced to a previous repair. Best advice I've ever been given as a tech.
that is true 83% of the time
Meh, maybe if the vehicle is relatively new still but otherwise I don't agree with that unless you took the vehicle to an incompetent mechanic last time. 0% of my repairs have been due to a prior repair (I don't let anyone touch my vehicles lol).
Yah 90% of this job is half mental.
@@stinkycheese804 I let someone else work my vehicle once installing a different engine. He forgot to install pilot bearing. I lost first the clutch then later the manual transmission!!!
@@SouthMainAuto 😀
"Dual Sport, whatever that means." "Hey do you know if this is the DS or the Base model?" LOL.
Word for word what I came here to say.
Crossed plug wires, always a nice find. Cant count how many times Ive done that. You try so hard to make sure their correct, and still get it wrong !
Well I usually do one at a time or use different colored nail polish, and a key, e.g. Green cylinder 1
I literally just finished doing a full tune-up to a 2002 MAZDA B4000 with the 4.0L. I couldn't understand why the truck was running so rough and throwing a P0174 Code. I checked to vacuum leaks and all that stuff. Then I bumped into this video. Lo and behold, I flipped wires 5 and 6. 🤦🏽♂️🤦🏽♂️ Valuable lesson learned here. Check the obvious things first. Thanks for the teaching my friend. 🙋🏻♂️
Can say as a backyard mechanic, every time I have a misfire on my chevy's, after touching the dizzys, always step back take a breath and check the wires. Almost always find a wire crossed. Key is not to panic or you will start throwing parts at it...
The same thing happened to my uncle Tony after he tuned up his old Mercury. Lucky for him i had a chilton repair manual that covered his car. Wire firing order corrected, and good ole uncle Tony was happy. THANKS FRIEND.
Class move on your part... Brother makes a mistake anyone can, and you just go on like nothing happened... Nice!... My brother (rest his soul) would have made sure the whole world knew it and given me a hard time for days, in a joking manner, but still, drill me for it... Just another reason why I have so much respect for you. Wish you were back west here in Beaverton, Oregon... Thank you Eric for all the knowledge you share...
Ever since my OTC Genesys that I got over 10 years ago, I completely lost faith in OTC scan tools. That thing never failed to disappoint.
Hello Eric . Staten Island resident , subscriber and fan here . It's nice when good folks like your
Self and Ivan ( motoyam82) make the long haul down here to get us on the map . Appreciate it and your hard work and commitment , both you guys . Thanks and keep up the videos , we appreciate it.
Lord knows in today's high tech world , us curbside / backyard mechanics can sure use a hand .
Thank you Dr. O ! I really enjoy your videos. I find myself shrinking into the fetal position whenever I see someone pulling off plug wires on a running engine. I used to work in a tune up shop and have taken several jolts from GM HEI's and the like. I actually took a jolt to the chin while leaning over the fender of an Audi (I was kneeling at the time). They say the voltage won't kill you, it's hitting your head afterwards that kills you. Either way. Love the videos ! Sincerely, Sparky.
I'm so impressed you were able to make that diagnosis without checking firing order. Yeah, two cylinders and recent work pointed the way, but without the details in print I wouldn't have had the balls to swap those wires.
On the scan tool, I think the DS stands for Dual Sport.
We used to have John Deere 310A's back in the day, they did us a good job. Our newest one now is a 310SK - nice machine!
At least it was a simple mistake! Those are the good ones to make. :D
The first timing chain I ever did, I was a tooth off. Fortunately, no damage! Unfortunately, it was about a 4 hour job to get back into the timing chain to reset it. Hard lesson, but never forgotten!
As always great entertainment, thank you!
Your right, had my van 24 years and most of the fix in I done to it was because I messed son thing up but after about a decade or so I started learning, sad my van is almost rotted away and its only 24 so young! it's barely broke in with only 300k on it I think the motor will outlive me but the salt THATS YOUR PROBLEM LADY! great video.
Beautiful scenery!
Eric I love your videos man. I can't get enough of them. Nice of you to help out your bro. Tell him we all been there before, you just learn from your mistakes and move on. Thanks for educating us and keep your channel going bro. Tell the family we love them in the videos too, even the little kitty, hahahaha. Greetings from New Hampshire.
Well done and beautiful countryside Eric.
How nice of you to help your brother :)
I just discovered your channel, love it! Im a machinist by trade and i'm really enjoying your knowledge in what you do. From one tradesman to another, id have you work on my vehicle any day! Keep up the good work!
Bet it was good to see your brother again!!
Eric, thank you for the lovely scenery of NY State other than the usual shots everyone sees of NYC, reminds me of the Fraser Valley out here in British Columbia Canada where I live, hilly and farms where the food comes from! Granted 45 minutes to the east and you enter the mountains and man oh man does it get pretty.
Nice video Eric. that scan tool looks handy. It's just to easy to miss the basics when chasing faults well spotted. Great to see the brake cleaner back.
Amazing what you can fix with "scope on a rope" and diagnostic tool. Great job!
and a can of brake cleaner
Yeah a lot of gravel here in Iowa, but no salting in the summer. Looking forward, hopefully, to more Outdoors with Eric O Videos.
Loved the sign. “There is nothing here worth dying for”
Know you done it! I am totally addicted to your channel!!!
Thanks mate, really help for own bro, bless your heart.
replace one wire at a time is the answer!
I change them all at once, but I always have a firing diagram with me!
that works as long as the previous person put it on right.
another great video...i have been humbled recently on some simple oversights!
That was pretty damn impressive.
Great diagnosis.....
Ah, the dinging! Please make it stop! 😊
How cool is it that your brother and I believe you have said your dad and you are all mechanics of some sort pretty neat
Another good video great job. And that could have happened to anyone. I have crossed spark plug wires before. Now when switch wires, i do one at a time.
We have all been and done it ;-)
Eric, I’ve only lived in New Mexico and Arizona. Our cars are spotless on the bottom. I have a 2006 that looks new from underneath with 137000 miles
nice fix
Nicely done, no parts required! Surrounded by dirt roads here, need to build a sump guard for the race car to stop it grounding out.
Amazing on a Ford system. I run into it constantly with obvious misfire no light and no Mode 6. Very frustrating , at least GM uses Misfire data on earlier models to help with Dx. Bank 2 is easily mixed up on Bank 2, had that in the shop i work numerous times. Good video
Simple mistake but I learned something from it. Thanks!
Wow!!!! I never would have guessed this 😱 ETCG reviewed this Encore I'm looking forward to see how u feel about it. I'm thinking about getting an Encore or an Autel.
Wow! I have change plugs and wires on many cars but the only one that I messed up on that sent me on a wild goose chase was the same engine as this Ranger. It was a 3.0 Vulcan engine in a Taurus.
Great Video! 2 cylinder misfire dumping twice the air at the 02 on B2! Simple enough math, but I learned the hard way about not pulling plug wires out of a distributer or ign coil! MAN THAT HURT! If you use a grounded screwdriver that would work/won't light you up! Oh ya. ICE CREAM! THAT LOOKED SO GOOD!
If you use a grounded screwdriver, that would work! Sorry for the double comment. Nice job!
how dangerous is it to pull out the ignition coil?
Following your strategy for diagnosis. You help me.
Loved this one! Also that Encore seems cool!
Yikes. I feel bad for your brother. Nice fix. Nice new scan tool as well.
I just fixed a Fiat Punto. No start due to no fuel pressure. It was actually the ECU. And it had a bad coil causing misfire and poor running. It also desperately needed a service.
What could be better at the end of the day than ice cream and cruising the dirt roads in your Tundra.
We have pretty much zero dirt roads in the UK. Except on private land. Really bad paved roads with pot holes and weeds growing in the middle is the worst it gets in some rural areas, the Scottish highlands and on the west coast in the republic of Ireland.
wowww!!!....awesome video!!!....this went totally over my head!!!... I have to study this video really hard!!!!....what does the test light have to do locating a wrong firing order???.... I did not register which spark plug wires were swapped!!!!!....totally amazing!!!!...congratulations Dr. O!!!!....greetings to all at SMA!!!!
Your a good brother thank you for sharing 👍🇺🇸😎
Liked for just the sign at the end!
Those roads up there around the finger lakes were a a riot when I was up there, Big change from the NYC area Close to PA they have those red clay roads that cakes your vehicle.
Good video, thank you!!
Great video.
Really enjoyed this vid.
Nice & easy fix!
Great video man.
love the videos down in Louisville KY.
I'm calling *BS* on this whole video. You just wanted ice cream.
Damn that delicious ice cream!
OK fine... you got me!
hey brother, can you swap some wires so I can do a video ...
I mean for new wires, they are looking a little dirty ;)
Hard working man can get some ice cream when he wants :D
That's what brothers are for. Help first rag later. Happens. Get your hands crossed or Interrupted and there you go. I swap plug wires one time and I had a wicked intermittent mess couldn't figure it out I traced each plug wire out everything looked right. Course it helps if you make sure all the plug wires are push all the way down on the plugs and all the way into the distributor cap! Hey was hot out. I was too young to drink beer! No big ones Scott you didn't break it. You got a great brother he had it over there his family should and you got it solved. It's all good
Forscan is a great tool for Fords. You could watch misfire pids as the events happen.
That Ice Cream. You and Ratchets and Wrenches are something
Love ur brother! Love it man! Good job!
Did that myself once.back to basics found it.
One well-earned like
Another Great video!
Another great video. Props to your brother for letting you share his mistake. Would you consider unpacking some of the Mode 6 tests and concepts in future videos?
Lol I like when my brother screws up, I love when my dad does it!
Yep. Fords have to relearn the crank wheel/sensor correlation before they can detect misfires. Resetting codes wipes that calibration out. Requires several non braking decel events. (Think coasting down interstate off ramp)
beautiful
LOL...."Rookie mistake"! As always love the videos!
I got an old Isuzu trooper for neary free 10 years ago. The prior owner was drinking when he did the tune up, and couldn't figure out why it miss fired so horribly afterwards. After I bought it, it took me the weekend end to figure out he had 3 out of 6 plug wires switched. Sold it 5 months later for $950. I miss that ol beater. Was a beast in the snow and offroad. Isuzu made some of the toughest suvs back in the day, shame they got so far involved with GM.
I have found, in my long life, that it is seldom a good idea to bust someone too much about a rookie mistake. There's only two types of mechanics; those who have made stupid mistakes and those who will. I remember an instance when a person I know had the engine in his car completely rebuilt. Afterward it had no power. Didn't misfire or anything but just was totally weak. Long story short, I convinced him to bring it to my friends shop. Turned out, the guy who rebuilt the engine failed to disconnect the vacuum advance before setting the timing. Once the timing was set properly the engine ran like new. Rookies aren't the only ones who make rookie mistakes.
Agree. I'm a DIY'er, but I've worked on my own cars for a number of years. I was replacing the valve covers and gaskets in my mom's Altima, and I was sure the ignition coils were hooked up correctly. Long story short, it had a horrible misfire I couldn't figure out and had to be towed to a shop. $400 later, including the tow fee, it was back to normal. smh. One thing the shop also found is that a pro mechanic had crossed up a couple vacuum lines, so I didn't feel like a total moron. Well, yes, I did.
I felt a slight miss driving down the highway in my 02' Ford Ranger XLT 4.0L and drove it into the the Ford Dealership. I had to initially paid for the Diagnostics Test that showed a misfire at Number 5 cylinder. I had them install new plugs and plug wires as recommended, and an hour later I was back on the road. I request the same trusted mechanic that repetitively works on Ford Rangers and gets to the point, does the fix, road test it afterwards, and evaluated what repairs I may need in the future like a valve cover leak, which he did the next day. My truck is 19 years old with 174,000 miles, and I'm retired now driving only 3000 miles a year. My truck runs, drives, and looks like Show Room Condition. It's the best $19,000 investment I had ever made, besides my 1998 Ford Ranger that was totaled in a head-on collision from the other guy on the wrong side of the road. The shock of impact traveled through the whole truck to where you couldn't open up the tailgate. If I had the money I would buy a new ranger, but they want double now for what I paid for mine.
Great video Eric. I learned something. :)
thanks got to order one good stuff
thank you again
This will definitely tweak bros pride him working on equipment like dad. Boy for my first set of plug wires pulling them all out sheesh.
This is why I love your channel Eric O!!!

Thankful for my Country here on the day before Independence Day 2020!! AND THE SMA CHANNEL!!
Perfect video for today I'd say!
Oh, did I mention Car Repairs..... LOL ;o)
Great Video!! SMA! SMA! SMA! SMA!........
What a talented family. Sometime tell us about your dad and brothers, etc etc. We like you and want to know that stuff.
If people didn't make mistakes , they wouldn't put erasers on pencils. Usually keep my erasers wore down to a nub. Nice video Eric and great channel !
Nice !
I seen fire jumping everywhere!!
I've done that before. Was running on 2 cyl. It was very prone to stalling guessing due to it being a 4L cyl
always fun to catch your brother's mistake...just don't rib him too bad. It might come back and bite you on the butt. LOL great quick video...Well quick to SMA norms. see you in the next one -John
Would love a comparison review between that OTC unit and the Autel! Also compared to the Snap On...eventually I wanna get one.
Cool I have the OTC Encore too.
It's a little slow
Been there myself. One more reason to buy the Motorcraft coil. It has the cylinder numbers on it.
The coilpack on these last gen vulcans have a 123|564 pattern instead of 456... very confusing to many people, its an easy mistake to make and even miss on second inspection....
Good video, once again.
Misfires and O2 sensor readings can be confusing.
Like this example, it probably smelled very rich, yet EMC saw low O2 signal (lean) (like you said, O2 doesn't care about fuel, it only can measure unburned Oxygen).
ECM sees low O2 signal and responds with fuel, and STFT & LTFT go through the roof until a DTC is set.
Thanks for the great information.
I remember when I was a kid growing up on the east coast, the dirt roads to lake side camps and rural access roads were sprayed down with, I think, creosote or something of that nature, to keep the dust down. As I recall that changed while I was still pretty young. Hard to remember that far back with any clarity. Stuff happens. All the wires look the same...what do I do now? Thanks for the video.
I would like to see more of detecting plug wires that are in the wrong order. In this video I lost you. I couldn't follow your trouble shooting. Great video.
bRO GOT'S A GREAT NAME, DUDE!
Easy peasy tell your brother I heard him swear after you cut the video. Sure is nice to have family that helps each other.
great info on trouble shooting buddy we all make mistakes so dont be to hard on him
Are you still doing Outdoors with Eric O? I'm just curious because I really enjoy that channel! Thanks for your time sir.
Ignition Coil connector/ pigtail goes bad too. I had 2 go bad on 99 B3000. Didn't find it until I spent $$$$'s changing coil, wires, plugs... everything.
STANDARD MOTOR PRODUCTS S658
When I was a kid they would have oiled those dirt roads. Worked fine.
Mode 6 is cleared when codes are cleared and on some fords its cleared by reading dtc's.sometimes after clearing dtc's the pcm needs to relearn the misfire profile correction to flag misfire dtc's.if not it won't detect misfires and just flag the lean condition.hope this helps.
Nice 👍
