- Testing spark plug wires and diagnosing bad spark plug wires. Learn how to test spark plug wires with a multimeter. If your car is stalling, idling poorly, hesitating, getting bad fuel economy, misfiring, or you have a check engine light, you should check your spark plug wires. This will also show you How To Fix P0300 random misfire codes in your car.
There are 3 main tests I go over
1. Water spray at night (look for sparks)
2. Visual inspection (cracks, burns, etc)
3. Using a multimeter (ohm meter resistance test)

Chris, I'm about 65 years old and working on cars were long time and I would like to say you're doing a great job on the videos.
Keith Lamport Thanks a lot Keith! I appreciate your feedback!
You are right sir,
Chris, I to am 65 y/o like your videos....When I change spark plug wires I mark the cap & wires with paper tape and number them so I don't get them mixed up....this is for people who may get the turned all around...
im 68......and still remember , me stripping down my 62 ss impala blk/red... and me and the boys pushing it up the driveway....and leaving it under the Penn railroad trestle in J Hts Q Ny one summer day... my point,,,,,,,Ahhhhhhhh hhhhhmmmmmmmm,,,, ...I forget.... butt keep on doing what you do...
Thank you so much for your name is jobs that the errors in hand to be a good day at our place. Florida State Tyler Johnson said the errors in hand to be a good day at work
Awesome video. Worked on cars throughout the 80's into the early 90's. Carburetors, distributors, etc. Then I lost my garage due to divorce. Didn't open a hood for 20 years. When I finally did I didn't even know what I was looking at. Went to work and learned these ECM controlled engines. Now I'm doing my own work again. Thanks a lot for your awesome content!! New sub here!!
👍👍👍👍
That spray bottle trick was a good idea! I saw sparks and then tested my wires with an ohm meter and saw they were bad! Thanks a lot!
Thanks and glad you diagnosed your wires!
i licked mine and got killed
What's should the reading be?
Water test is for sure the best method i have ever seen. Little cracks can't hide from water. Thank you for the great info.
@Mr Hansen it isn't lazy to be logical and save yourself some time. More like the fastest method.
That water test saved me a huge headache! Been tiring to diagnose a misfire on my Mazda Lantis for ages!
I love your channel. Your guides have helped me not only with my daily driver, but, also with my classic project car.
I'm currently replacing ignition wires on my project car. It's a 1959 Ford Fairlane Galaxie 500 that was owned by my Grandfather. It has been garage kept but hasn't been run since the mid 1960's.
Thank you for your content!
Fantastic how-to. Thorough explanation, great demonstration of concepts and techniques. You aren't just showing how to do these tests, you are showing how to show things.
The best teachers a more than just good at the craft.
They're also good at relaying information.
That's why you can have working professionals be some of the most useless teachers. Despite being a Master of their Craft.
This guy is so good, he can even turn off the SUN!
Great videos though.
James Kinyanjui Haha, thanks man! Glad the video was helpful!
@@chrisfix sir, my car i20 has 2 separate coil packs controlled by 2 wires connector which controls 2 high output terminals. However, one high terminal pin 4 of first coil gives less spark than pin 1 on the same coil pack. Why such less spark being provided by the same primary coil??
VERY GOOD INFO. THANK YOU!!!
Thank you so much Chris, I had a very rough idle and bucking at 70mph.
Troubleshooted and replaced parts after parts for 3 full days with no luck.
Just a hour ago I did your spray water test and discovered one lead was burned by the exhaust with no insulation left, and was grounding out!
Thank you so much!!!!!
+Hector Garcia-Martinez, I cannot reply to your comment for some reason, but you can check your spark plugs visually. I will make a video on this but for now, look at the ceramic and make sure it isnt cracked, look at the tip of the plug and make sure it is gapped right, and look to make sure there arent too many carbon deposits on it. It sounds like you got platinum plugs which last 100k miles so dont worry. I had plugs from the factory in my van for 200k miles before they were changed and she ran fine. You will experience a rough idle, hesitation, etc when your plugs are starting to go.
Ok. Thank you..

ChrisFix Scott said u are wrong on another video what's up with that 🙄
I have question. Right now I have spark plug 16mm (hex size). Can I put 21mm (hex size) spark plug ?
Hey, great video Chris, and good background info - I always like it when people explain the 'why' and not just the 'how'. Thanks
James Booker No problem James! I am glad the video was helpful! New automotive 'how to' videos every Thursday and most Mondays so stay tuned!
I like how your older videos sounded like you just woke up and started recording, and your newer videos sound like you just discovered coffee getting all fired up to do car repair videos.
Lol I never thought of it that way
I have seen many videos on this subject and I can easily say this is the most informative, hands down. Great job! You’ve got another sub.
You are my teacher for automotive. ..thank you so much for your kindness to share your knowledge
As always, a good visual tutorial from Chris. Thanks.
Hey man you’re awesome I’ve done so much work on my car and saved thousands thanks to your videos , I can’t seem to figure out why my AC keeps coming on and off and it gets worse when it’s cold outside
This was great. From simple no tools to more tools. Thank you.
Amazingly useful and on-point.
Thanks! Glad the video is useful! I try to make all my how to videos concise, educational, and watchable so that anyone can fix their car!!!
As a fellow Jersey guy, you are the best "go to guy" for automotive repair and knowledge. Hope to meet someday.
Great video, straight to the point. Easy to understand. Thanks.
Thanks a bunch. Super video. My boat engine (2 cycle) has old plug wires that have "tarnish" on the terminals. I have replaced two of them. It seemed to help my engine run a bit smoother but there is an occasional miss or rough idling. I believe I'll replace the other four wires as well.
Great video. Another subscriber here now! I never thought of the mist test. I had an intermittent miss that wouldn't throw a code since it wasn't exceeding the threshold for the number of misses the ECU needs to rigger that code. I changed the rear coil pack due to the connector on the coil being loose but still functional. The miss went away. The coil was working fine but I did reroute/move ALL of the wires to do this. I bet I have a insulation breakdown somewhere and I've already bought new Motorcraft wires and plugs anyway so I figure 21 years (98' ranger) and 243K miles on the original wires isn't bad. OEM stuff really lasts! I have no idea how long the plugs have been in so they need to go anyway. Bet it runs like a new engine! Thanks for your time making these vids. They are helpful for the DIY'er.
guess it's time to order 16 of them for my old s class. thanks Chris!
Thanks your videos really help. And becoming a mechanic after wacthing each video
Thanks Chris, as always a very useful video. Please keep making them as it makes doing a job much easier 👍
Great job Chris. Excellent video
An excellent clear to the point guide 👍
Thnx chris i had noise on my radio , finally solve it 😍
Hey Chris, thanks for another great video. I have a 1980 camaro with a 383 stroker that I built. I keep burning plug wires which results in a cracked insulation on them. Headers get real hot and just happens over time. Even with Kevlar boots they still do this. Eventually tried header wrap combined with the hoot and haven't burned one since
Really good presentation Chris .Informative , and it moved along smoothly .
+Richard Butler Thanks!
Like I said before, you the greatest mr. Fix
Thanks!
Thank you for the explanation Chris!
Hi, Chris. Thanks for this video. Today I could able to detect spark plug wire defect with the help of your video.
Awesome! Glad the video was helpful

Great video. Easy to understand. Hopefully this helps me figure out my misfire in Cylinder 8 code.
Great info Chris. Thanks for your wisdom
all your vids are fantastico man!!! keep it up yo
Thanks a lot man! Will do!
Chris! you just saved my 97 Corolla from the Junkyard. Thank you so much!
I changed my coil and spark plgus but car didn't work properly. So i tested the wires like u did with multimeter and one of the wire were broken. Thank you for the video, helped me a lot.
Much appreciated. Thank you for your time and your video.
This was freaking awesomeI Great video!! I really got a kick out of your Water Miss Test.and your Multi meter part really help me understand the Mult imeter. I was lost in school about the different functions. And we all know how important Electronics and testing them on vehicles are now a days. I'm gonna go check if you have a video on how to use it fully. Thank you again for these uploads!!
chrisrefaei Great and no problem bud! I am glad the video was helpful! I do not have a multimeter video yet, but it is in the works!
Thanks Chris, always helpful
Thanks a lot!
sparking under water mist was a cool new tip to me thanks Chris
Chris… You are awesome man!
I love your videos Homie!!!
Thank you buddy that was a good video I never thought about the misfire test at night we could see the spark that’s a genius
I'm glad the video was helpful!
This guy is great. Like everyone need to be like him. Step by step. Most just make a video and send it out lol idk if they every review their stuff. Or rehearse it nothing wrong with that.
I love this video, the way you explained things to details. My problem is I just bought spark plugs and wires not too long ago and two of them will not connect at all on my tester and read anything, so I'm going to try that SPARK in the DARK method. 😂
Yes I finally found my dream channel
Cool tests bro! Thanks for the uploads.
+thealvaco Thanks!

ChrisFix Subbed!
Someone told me to check my spark plugs and I didn't know how. Lol. But thank you. You got a sub from me.
Never heard of the water mist trick before. That is a new one I can add to the bag of tricks. Thanks.
***** Awesome! Glad the video was helpful and taught you something new!
Excellent and glad you showed that a multimeter has more purpose then just showing battery voltage lol. My friends been bugging me to buy one or use my “ohm” meter. I let him wait a bit since he’s a pain in my butt and went over and said I’ll bring it. I got there there and said “hey can u grab your multimeter just wanna make sure they read the same voltage on battery” Then I switched to ohm “20,000” and tested his allis chalmers tractor wires and various other electronic components. “I heard him say” “you a** hole”. Lol. I just smiled and told him to use the inter web lol
Great vid. Like from me. Lifetime ASE certified mechanic
Very smart...great teacher...Thanks
Nobody else has ever diagnosed the high pitch radio nois! Now I know why I heard that the other day, thanks. Will change the spark plug wires, plugs, and ignition coils soon, before the 100k mark, car is at 85k currently and yesterday just heard that radio high pitch noise
I'm glad the video was helpful!
Thanks dude. On my way outside to check mine.
Thank you Mr. Fix
classic chris fix. this video is great!
Really good info! Thanks so much. No wonder I subscribe months ago!
Thanks Chris, u are the best
I should try this with my outboard motor. One of my small outboard can't get over 3000rpm or high speed. In visual the cable somewhere crack and looking bad. I should perform the multimeter test for it
Thanks for your great tips! Really clear to show how to do for me as i am new for engines.
+Jerry Chan Awesome! I hope that it is an easy fix! Good luck!
Thank you. Appreciate this one.
I love ur videos chris. thanks
Awesome video, Thank you.
You are the man BOY !!!
thanks, great video and instructions
Great heads up stuff!!!!
great video thanks!
wow 3 million subs already! thats great
Well done video. Thanks.
Really appreciate your videos, Chris! Always very informative and very well done. I hope you're making some good income off of these, as it's well deserved.
I'm going to check my wires using your methods, but is there a general rule as far as mileage goes as to when you should replace them? Answers to that are all over the map online. I have a '97 Toyota 4Runner with the 3.4 liter that I just put head gaskets on and it seems to be running slightly sluggishly since the rebuild. Of course, I parked it and waited two years to repair it after one blew, so for all I know it runs no different than before! Gotten used to the new car maybe. I put fuel stabilizer in when I parked it and have now run several fresh tanks through it and replaced the fuel filter, as well, which seemed to help slightly. New plugs were installed right before the head gasket going. Thanks in advance!
Good information
Thanks
thanks very much for the very helpful tip on my engine misfiring problem.
Emmanuel Santiago You are welcome! Glad it was helpful!
Excellent---I'll subscribe and see what you've done since them (4 years ago)
Hello Chris. Thanks for the videos man, you always make them full of helpful info and simple explained. I have erratic idle and that's "killing" me. It's interesting you pointing out about the high pitch radio noise. Its like 1 year that I hear that noise from time to time and I have thought it might come from some air conditioning tubes or valves. Sometimes I hear the noise even if my sound system is off. Does this noise definitely indicate that the coil wires are to be replaced?
Very good clear video, you know your stuff.
