EXCELLENT video. Not only do you show it being checked, but you actually TEACH us how to check for ourselves. I wish all youtube car videos were like this. Thank you for making it.

Thank You SO MUCH! I was able to narrow it down to a bad spark plug in cylinder 3. I replaced all 4 spark plugs for 20$ and runs great! Saved my mom money by not bringing it to a shop. THANKS AGAIN!
I have had my forerunner at a certified Toyota mechanic shop. for at least four years similar situation and no one can tell me exactly what’s going on. Your video has been great and explaining and diagnosing the misfire. I now can’t wait to try it out thank you so much.
Thank you very much for the videos. presented in a logical and realistic way. i like how you use customers vehicles for the repairs, can't get more real than that, real world situations.
@@realfixesrealfast i literally just used this method to fix my neighbors buick park avenue. It was running really pporly and by doing this I discovered that it was only running on 4 cylinders. Thanks again!
There is a leak in the middle cylinder coil boot. High kv under load induces the spark to go to ground via the spark plug port. No load kv at idle will allow current to flow through the spark plug. I would love to work with guys like this. Great video I'm sure this will help a lot of newbies.
Man I love these videos where we have to guess what the problem is!! It makes it so much more interesting! Duane you are a true professional and I can tell you love what you do. :]
Really nice video I think you showed us that we really may not even have to use the paper clip trick at all since by pulling out each core individually gave us indication of spark and yet did not indicate which cylinder was mis-firing until you raised the core itself. Simple enough for me. Thank you much, Keep up the great work!
You gave me a good lead on how to fix my issue. I started per your video but also placed a timing light at the end of each wire by the plug and found on wire was bad. Replaced wire and runs as smooth as new. Thanks for posting.
Thank you so much it really helps me out i hade the same problem with my car take it to 3 mechanics and none of them told me what was the problem they just told me to take to the dealer cus they couldn't find nothing so after a couple of videos i finally found wht was the problem thanks to you i save a lot money
Great demonstration of logical troubleshooting 👍 . I believe the cause of the misfire to be one of the two plugs fed from the center coil which was not contributing under load. It is possible that maybe the center coil is breaking down under load - however when you lifted the center coil out of the spark plug well - it appeared to have a good spark jumping / arcing from the spark plug boot - so I am thinking that maybe the center coil is still good. 👍🧐✌️✌️
EXCELLENT instructive procedure for spark wire coil and plug diagnosis. the ONLY flaw in the whole video is your statement that spark is coming UP from the bottom of the plug. It is not, it is coming DOWN the wire TO the plug FROM the coil and choosing the apparent path of LEAST resistance and going down the side of the plug in the carbon filled crack to get to ground where the plug screws in to the head. So it does not come UP FROM the ground point it comes DOWN from the coil Voltage travels + to - not the other way around.... But needless to say that changes nothing if someone does not know that it will not hinder the purpose of this video in any way anyway. Absolutely fantastic video other than that pick at you point well done. I am a Mobile Tech been doing it since 1994 i actually helped a customer avoid spending money with me and CURE his 1997 3.4 toyota misfire with THIS video as his aid (send him the address) so again, great job thanks much.
Man. My hemi is misfire crazy with zero codes. New motor. New plugs. Old coils. Runs great. Only misfires under load around 3k rpms. This makes me think i have a bad coil. Gonna test them like this. Thank you.
You could swap the coil pack to see if the trouble followed to another cylinder, and if it does... coil pack, if it doesn't... spark plug. Great video illustrating basic/advanced troubleshooting skills! I think I'll subscribe!
Thanks!!! for share your experience! I did have a problem with one coil in my Hyundai, I did the test only to a normal speed; I could not find the one that did not work. You help me to find it out the one that is not working!🙂🏆🏆🏆
When you shorted the ground wire the flame was the same size on each. As you pointed out, if a wire is bad the flame would be bigger, because of more resistance in the natural pathway through both plugs on that circuit. If either plug was bad, I would expect a bigger flame as well, for the same reason. So, those of you who say it's a bad plug are ignoring that part of the evidence. Of course, inspect the plugs, but I think it's something else.
could be the coil, but really could be the wire as I found in my problem with a 2000 Chrysler Intrepid. I did the same but then switched the coil on the misfire with a coil from one that was firing to see if it was in fact the coil, but all coils on that side worked.
Suffering Saints and Angels, Batman! This guy is incredible! We need to watch the conclusion, but i already suspect we've found the culprit. It's time to close the gate and spring the trap!
Very old school would call for a coil replacement. I once had a bad coil on a 1959 triumph motorcycle. I found myself driving into eagle pass, TX to a general store and bought some birthday candles and a roll of electrical tape. Meled candle wax into the hole and wrapped in electrical tape and the bike ran very nicely after that. Back in the 60's thats all there was to eagle pass.
Very important .. As a pseudo mechanic.. I cut tip of boot off as far as I felt safe. To get them to snap on. And thus began firing my spark plugs. On the side where I felt that catalytic had melted down. Or became a second sun..
I would swap the coil pack in the middle with any one on the out side, if the misfire go to the outer cylinders then I could say it is the coil pack that is defective. However, if it remains in the middle cylinder then I would conclude that the spark plug is defective.
hello, i read this and agree with you. however, i have an annoying one. what if after concluding that the plug is bad, you replaced the plug on the bad cylinder just to find the misfire still remains at the exact same cylinder. would you suspect that cylinder to havr a bad compression or a bad PCM??
Thanks so far. Number 8 when under a load seems to run good but idle and to 30 miles an hour smooth out. Engine light will not go off so no tag Mike chattanooga
coil 2/middle, under no load or just on idle still was firing when you pulled the s.p.boot allthe way out.....i am thinking bad s,plug or coil is failing under load...hence need coil. you guys are a big help,,,,thanks joe boston ma
I have a ford e150 5.8 very smooth until held steady 35/45 then slight missing. New ignition control module plugs wires distributor. Very smooth until high gear.
Next step, now that you know which cylinder is missing, switch the coil with one next to it, and see if your problem moved, if not, replace the spark plugs if you don't know when they were done, and if that doesn't fix it, you've got a fuel problem, or a compression problem.

Finally found a video that actually helps. Thank you sir.
Picked up an 06 CTS few months back. After engine poped on, found a P305. Been driving, but now time to correct, and this video really helped. Bear
Excellent. Very practical clip. Well done, sir!
Man I love these videos where we have to guess what the problem is!! It makes it so much more interesting! Duane you are a true professional and I can tell you love what you do. :]
I love the videos on checking out your faulty car engine parts. Keep it up
Thanks for sharing. You are such a good teacher. I experienced the same problem on my Toyota RAV 4.
Very nice and professional explanation. I will try that on my Z3 and update after my diagnosis.
Thank you for being a Teacher ... Thats sooo Ol School ... But Faithful ... Great Video ...

You could see the hoses actually stopped vibrating as much during the clip test
this was actually very very helpful and i learned how to test spark plug wires easily
Excellent diagnosis, thank you
Thanks for teaching us personally I appreciate it your time really valuable 👍👍👍👍

Good explanation, thank you.
Wow great video. The rear bank of cylinders on my Ford Edge prevent access to the rear plug’s coils but it’s good information for the front three!
wow that's a new trick i never thought about using wires..nice video good job
Absolutely great video thank you so much
I just learn something new today. Good vid
Excellent video to repair olds cars. Thanks
thank you that now l know how to test my coil pack n spark plugs

Thank you sir for this detailed info on testing the coils. You also remind me of Ed McMan from the Johnny Carson Show. :)
I love this video.. Really useful. Thanks a lot.
ty for uploads qualified mechanic by paper, but I don't have much diagnostic experience I m hoping to start my own mobileshop soon.
Thanks that's helpful! I will try it.

This is an old video but super helpful! Nice work

excellent video! now i wanna see you do this on a 5.4 expedition
Spark plug or a cracked plug. also check for carbon track on spark plug and boot.
Very old school would call for a coil replacement. I once had a bad coil on a 1959 triumph motorcycle.

Meled candle wax into the hole and wrapped in electrical tape and the bike ran very nicely after that. Back in the 60's thats all there was to eagle pass.
Coil #3 or passenger middle is bad. Great lesson. Thanks
thank you sir ive learned somethin g today thank you
Very important .. As a pseudo mechanic.. I cut tip of boot off as far as I felt safe. To get them to snap on. And thus began firing my spark plugs. On the side where I felt that catalytic had melted down. Or became a second sun..
Too awesome
I learned something today so it's a good day to me,,I'd say bad boot,,short or something
Good man. Thank you
I would swap the coil pack in the middle with any one on the out side, if the misfire go to the outer cylinders then I could say it is the coil pack that is defective. However, if it remains in the middle cylinder then I would conclude that the spark plug is defective.

then its a bad fuel injector
Bigvik Or a burned exhaust valve.
Oops burnt valves.
or change both coil and plug
