Excellent video. The "old timers", such as this guy, are always the best. And look, he diagnosed and fixed the problem WITHOUT a scan tool of any kind. You don't "need" scan tools. Just experience, common sense, and a systematic way of troubleshooting.
Thanks for giving me the understanding of my vehicle. Being a female I feel being knowledgeable of my vehicle, will help me understand what the mechanic is telling me.
I'm so grateful for not only your knowledge but your skillful teaching, often times mutually exclusive. I have an interesting situation whereas I was a mechanic for over 20 years, (ASE certified for many). I lost my business 20 years ago because of cancer. I recently jumped back into it helping a church that helped me last year, ("fix it forward") a phrase I picked up watching Eric The Car Guy, (another great tech/teacher) . The Church actually has a shop with 3 lifts and some great basic equipment!!! My point is, as you can imagine I have a huge technology gap. Things have changed, but watching you has been a great help and I have helped dozens of people in turn using my years of experience combined with knowledge I have and will continue to gain from you. Thank you!!
+Joe Mikos Thank you Joe. Great to hear your sharing yourself and your talents to help others. Those are great gifts you are giving, and great gifts that others are receiving. Bless your heart.
That's an awesome story. Almost made me tear up. Getting back into the swing can be tough, especially with the rate things change now, but you are rocking and rolling despite your setbacks. Respect.
@@realfixesrealfast hi guys thanks for all your info (great stuff all around cant speak enough about how things are explained 30+ years for myself but always learning a few things from you guys awesome work and thanks for taking the very time to really send it home in the training now one question iam trying to purchase your power probe i think i saw and the amp tester cant seem to find it but will be buying them both (FOR SURE) if i can find them again always good to have that one extra tool in the chest lol. thanks and keep up the (GREAT WORK GUYS)
What a great teacher!! Such a great technique and ability to break down a complicated situation to it's parts, than explain it in simple language so others can not only learn, but internalize the wisdom and the process, but so they can move forward carry the wisdom with them, and be free of the need of a teacher.
Always love to know how to fix things and know why you're fixing it without using equipment. Only equipment you need sometimes is experience and knowledge. Great video.
I see a bunch of other people have already said it, so I'll just say Thank you. What I'd like to add is how refreshing it is to see someone start from nothing and build a case for the issue using only the facts. Almost everyone hears a noise and says "ah, shucks, that's your ______." Sure, you want the most likely culprit, but learning how to find the actual problem is worth more than any "this is how you fix ______" in the world. Thank you again! (I'm working on aeronautics, but your video taught me a valuable lesson on how to troubleshoot properly)
I love the education that you are sharing. I am a logic reminded person you have put this in terms understand I can implement everything that you have taught me. You are awesome that’s all I have to say you are a very thorough teacher in which case I’ll pray for good Lord above that you have posted this information. I cannot explain how helpful to me. Not to mention other people is well Irish blessing from the bottom of my heart
You cannot argue with Roger thank. i I am a HVAC technician. So following the voltage, For lack there of, is definitely a concept that makes sense to me. You are a good teacher thank you so much.
Ive had a cracked plug and replaced but i never replaced the boots because i had just replaced them 3 months prior dousing my tune up. i never knew you needed to replace the boot as well. thanks for the video. i always learn something knew every time i watch one
great job, when you posted the first vid i thought what an easy trouble shoot give me ten minutes with it and she would be good to go. or at least i would have an answer, if you go back to my post you will see i took a similar approach as you, then i started reading the comments what i learned was some of the things i take for granted when troubleshooting to come to a conclusion allot of people stumbled over... scanners are expensive but the knowledge of troubleshooting is priceless,
I had put in new plugs, wires and coils a year ago on a 2002 Mazda Protege 5. Couple of months ago started getting an intermittent miss. Finally threw a P303 code. (but that wasn't the problem cylinder). I was stumped until I saw this video. Turns out the "cheap" plug wire on cylinder 4 had a very small crack and this method exposed the flaw. A couple rounds of electrical tape verified the problem so now off to get new "better" plug wires.
To the 59 that gave this t/s diagnosis repair video a thumbs down you need to sell all your tools find another trade or career because it doesn’t get any better than this. Great info ❗️I’m old school also but also very new school on class 8 highway trucks, knowing old school helps t/s and understand how things work even though new school technology is incorporated. The best advice these younger people getting into this field I could offer is learn all these old school tricks it’ll take you a long way. I attended an AC Delco warranty school in the early 80’s we were told to throw our test lights away and use a DMM. I watched a young guy (fresh out of tech school) t/s trailer lights all day and never reached a conclusive diagnosis with a DMM. I helped him see how a DMM is a great tool but not for t/s light circuits, we used just a test light and within 30 minutes had a clear diagnosis and a repair plan.
Thank you so much. My 1998 Mazda Protege 1.5L had code P0303 cylinder 3 misfire. I changed the spark plugs, checked the vaccuum lines, and changed the air intake hose, and still nothing. I watched your 1-3 series videos and tried each of the spark plug wires to see if they would slow the idle down on the engine. Low and behold spark plug wire three had been cracked and you could see the sparks through the outside of the wire. Changed all the wires and so far, fingers crossed, its good. Thank you
Sir, I can’t thank you enough! Your excellent technical teaching skills and well thought out quality videos are exceptional. With your help, I was able to diagnose this same exact problem with my ‘02 4Runner and immediately solve it. And this particular video was 11 years old! Really appreciate it and thanks again so kindly for sharing your knowledge. 🙂
All that was really wrong is the spark plug.Duane replaced the boot for extra insurance,make a couple more bucks & to job completely correctly.Could have just replaced the spark plug but if boot goes bad within warranty period of tune-up,customer wouldn't remember that he/she declined boot replacement thus causing customer distrust or losing customer.I've been in this Business for a long time & Duane did best thing for himself & customer.Great video Duane
wow I've been trying to figure out what the sound was coming for my peugeot 206. its cost me 10quid (about 13usd) for new plugs and a plug tool, im super happy. Thank you thank you. keep the videos coming.
It's amazing how much we can learn thanks to the internet and folks like you who prove humanity isn't about compassion and greed, to be human is to help others.
I'm iraqi kurdish i don't really know how to thank you enough dear gentlemen. I watched all the three videos amazing info. That's what I'm always trying to pass but her where I live is like a jangle full of different animals all with sharp tooth. God bless you.
Very good common sense approach to finding your missing cylinders. If I did that test at the end of spark plug, I'd know that plug or wire is bad. There would also be the possibility of the rotary, dis cap and coil being weak. At least in the older days, it was a pretty simple deduction. Based on that conclusion, I'd think you'd change out the center coil because it was the only one that had no effect on the engine's performance.
I have a 2005 gmc sierra z71 with a 5.3. I was off-roading the other day and developed a missfire.. i watched your video's to give myself an understanding on what i should do... Not that you covered it in your video but i just had jostled a plug loose. I greatly appreciate your video's and would love to have more video's in this manner.
Thank you so much for sharing this!! Had saw your video earlier and checked the ceramic part of the plug I would have caught it but stupid me just looked at the tip of the plug. I ended up replacing a bunch of things that weren't even faulty, and was on the verge of swapping out my ecu before smashing the car with a sledge hammer. **Just a note for others out there who have a scope to hook up to the sensors, like i did. That stray spark will cause your sensors give bad readings leading you to think there is a sensor malfunction. You will also notice random voltage spikes on your supply and/or ground rail leading you to think that maybe your ground straps are faulty...Thanks again realfixesrealfast!
Thanks for this, my scan tool just decided to bite the dust AND I'm having a misfire or multiple misfires all happen at the same time. Great way to mechanically diagnose the problem in a methodical way.
Thank you for this is a great video . I love working on cars the " old school " way , without the scanners and etc. This way I learn more knowledge about the workings of the engine .
Good video - What is good about this video is the shared process and the logical methodical approach which led to elimiation of possible causes to obtain the cause and cure.
The crack in the plug may have been there due to a defect in the pocelene or it was craked during installation. The carbon track is a result of the spark traveling to the ground path. As Duane said, this will create a carbon track, if you will, in the boot. That is why, at the very least, you should replace the boot along with the plug. In a few cases, i have seen this type of issue damage the coil internally -causing an intermittent misfire. Great video - thanks Duane
That was great ty.. I have a 1997 Cougar 4.6. I bought from an older couple had about 83,000 miles on it a couple of years ago . Now has 120,000 but has a miss or cut out. Not all the time at first but starting to be more and more.. Those little scanners show no codes I replaced the coil packs but I’m checking the wires and plugs this week and I feel pretty certain that is it. Thanks so much
Good video. Thanks again so much. Its interesting that the open loop condition only affected 2 and 5. That would have lead me to the wires from pcm to injectors first to check for intermittent short to ground. I know that the injectors have their on driver. but its crazy how it singled out two cylinders on the same coil. That bug was being tricky. Thanks for following through and showing us how to do it..
you have to maintain a smaller air gap from the ground wire than from your skin. Do that and you will never get shocked. It's not fair for you to call this video stupid. It was very informative and a much greater benefit than anything you contributed.
great stuff, I know in my workshop a lot mechanic's would keep there trade secrets are secret not even share with apprentences,when I wanted to do diagnostic work my manager told me to do it on my friends car.....
Ah, the old carbon-tracked plug. Nice of you to bring up the point of replacing the boot too when you find one. I've fallen into that trap myself in my younger days, lol.
Fastest way to know if you have a misfire is to take a small rag or napkin, hold it to the tailpipe, have someone open the throttle and let off it quick, if the rag sucks in, you have a mis, but that won't point you to what cylinder.
Eight yrs later and your videos are still helping people. Thanks! Good video all around. I'm working on a misfire on a 99 Yukon 5.7L. Ran Cataclean thru and CEL went out finally. No other codes. Figured Cataclean would help injectors too. Did cap, rotor and plugs. Runs better but still misfire. Opened hood last night and saw three bad areas with arcs from plug wires. Got a set of wires on the way from Summit Racing (spiral core, 8mm 270 ohm). Will try spray bottle on wires to see what happens with engine perf. Hope it's not Spider injector poppets or fuel pressure. Don't have tools for that. Any ideas appreciated. Thanks.
For all those of you who say this is the wrong plug for the car, you're wrong! A lot of these toyotas call for a twin electrode plug. So if you know anything about Japanese cars or Toyotas for that matter... this the right plug. all you need some anti-seize and some torque specs for a job well done.
As an aircraft mech, we have a cable tester that impresses a high voltage on the cable to see if the wires "leak" voltage. Similar to megging a cable. We can't test under operational conditions due to prop hazard.But I think this would help in the automotive world since cables are the same in any internal combustion engine.
You make a good point, that comments from the group are really useful. I make it a point to go back to the discussion a few days later, to see what others said. I've learned a ton from all of those who make the effort to contribute. Can you speculate as to why the Varus failed to detect any misfires? Duane, I think I'm not alone in my feeling that these kind of seminars are great, please keep making them.
In medical profession I was taught "OPQRST": ONSET (WHEN DID IT START, HOW, SLOW OR FAST ONSET, ETC ?), PROVOKE (what makes it better or worse?) QUALITY (sharp, dull, loud ?) RADIATION (is it affecting any other areas") SITE (Where is actual rattle, squeak, sound) and TIMING (Certain time of day, certain activity, daily, weekly, intermittent?) Then with that info, I can go to next tests, "HIPPIRONE". Car guys sometimes start throwing parts at a car.
could be the water getting in, check the drainage around the windshield for: dirt, corrosion etc. I had the same problem with F250 pick up truck. I used a sealer in a tube from lowe's and it fixed the problem. If the spark plugs are wet they hold the moisture so take them out and clean them, if they are really black, replace them. Scanner would help to find out which cylinder misfires, auto stores can scan for ya for free, better yet get one.
@vgs8606 I agree. If you over tighten a plug, you will strip the threads in the head (being made of soft aluminum alloy). I wonder if Bosch still makes its plugs in Germany or if they moved their production to China like everybody else.
Try to check the other cylinders, if you got rotor check the correct wiring position or if you got coils try to change the position of then to see if there´s a missfire in another plug
This condition is sometimes incorrectly diagnosed as cracking. It is believed to be caused by extreme temperatures due to the spark travelling along the surface of the insulator. When deposits cover the shallow channels, the rate of insulator erosion is aggravated, the spark is masked, and misfire may occur.
@vgs8606 I don't feel that the ending was a let down. Diagnostics is all about the process, and starting with good observational skills is always the best plan. What I'm learning here is how to patiently listen to what the engine is telling me. Sure, in this case, closing my eyes and replacing parts would have led to the solution, too. But I find it immensely satisfying to get the engine to tell me what is wrong, before I buy possibly unnecessary parts.
Thanks! I recently purchased a used car, I put spark plugs in and about a week or so later it began to misfire, I guess I need to look at them plugs again!

Yes I was right. Excellent information Sir! Thanks
Love that you use low cost tools to find a tricky problem. Could you use a short spark plug wire to connect to the spark plug?
Loved these videos. You guys have helped me saved a lot of time and money.
could be the water getting in, check the drainage around the windshield for: dirt, corrosion etc. I had the same problem with F250 pick up truck. I used a sealer in a tube from lowe's and it fixed the problem. If the spark plugs are wet they hold the moisture so take them out and clean them, if they are really black, replace them. Scanner would help to find out which cylinder misfires, auto stores can scan for ya for free, better yet get one.
thanks for your efforts to bring us valuable mechanical information...
I know this video is old but still true. Much appreciated
Great video and good information thanks for sharing
Excellent job 👏 thank you sir for your time and effort 👌
Good stuff, thanks for the help when I cannot figure out what I am doing wrong.
Great Video! Doesn't assume I'm a rubberhead OR an expert.
VERY good work-find the problem, don't just change parts until you find it. Thumbs up!
Thanks! I found my bad plug with your help.
@vgs8606 I agree. If you over tighten a plug, you will strip the threads in the head (being made of soft aluminum alloy). I wonder if Bosch still makes its plugs in Germany or if they moved their production to China like everybody else.
Good. Job. I. Learned something. New.
Fantastic diagnosis! Nice superhero music too lol!
Yet another great video and excellent advice
Try to check the other cylinders, if you got rotor check the correct wiring position or if you got coils try to change the position of then to see if there´s a missfire in another plug
Thank you so much for all this information and for your experience and wisdom etc.
Thank you for this great videos
This condition is sometimes incorrectly diagnosed as cracking. It is believed to be caused by extreme temperatures due to the spark travelling along the surface of the insulator. When deposits cover the shallow channels, the rate of insulator erosion is aggravated, the spark is masked, and misfire may occur.
You show to ask how to find problem thank you to you,
Great teacher...
@vgs8606 I don't feel that the ending was a let down. Diagnostics is all about the process, and starting with good observational skills is always the best plan. What I'm learning here is how to patiently listen to what the engine is telling me. Sure, in this case, closing my eyes and replacing parts would have led to the solution, too. But I find it immensely satisfying to get the engine to tell me what is wrong, before I buy possibly unnecessary parts.
Excellent video. Thank too for sharing valve information
very helpful, you guys are the best a special thanks from Kurdistan always to you GOD bless.
Thanks! I recently purchased a used car, I put spark plugs in and about a week or so later it began to misfire, I guess I need to look at them plugs again!
I like all of your videos I have learned alot that I didn't know and hope that you continue to make more videos for us thanks ,Karl
That was a cool set of videos! Thank you for sharing!
