Thanks, Mr. Finn! My wife was going to take the Corolla down to the Toyota place for repair, but your video showed me how to easily find the broken coil and replace it. Your explanations made perfect sense, so I definitely learned something today. More than that, you saved me time and money! Thanks Again!

Thank you all your videos is very helpful 😬👌leaning all I can Toyota dealers love your money and also mechanics this was very easy hate it when they over charge you for a very simple job 🥴
Mannnn you jus saved me some money $$$ i jus found and changed the broken coil ... thanks so much i hope this comment finds you well during the pandemic and anyone else reading it thanks godbless
something about your voice is very clear and able to understand!!! alot of help my friend definitely subbing and i also found out I have two coils that are bad and will now know how to replace thanks to you!
I have a question. I replaced the rubber boots that go over the spark plugs and the kit came with those little springs that contact the top of the plug. How do you remove/replace those? I tried unscrewing them, but they just spin freely in there. I'd like to try replacing the springs before I buy new coils. Thanks!
Hi Peter I just want to ask for your advice, is it a good move to use a 800 grid sand paper to sand rusts around each ignition coils and put back, I would like for your help cheers 🍻
@@PeterFinnTheCarDoctor thank you so much Peter im truely grateful n thankful for your help and answers 🙏 and all you videos 📹 🙏 you are GOD send 🙏 😊 ❤ 😀 ☺ 💙
Hey Peter, when I try this unplugging 1 ignition coil, my car wont run it starts but shuts off as soon as it starts.. when I have them all plugged in my car works but rough
Lebron James did this help you diagnose the issue? Following Peter Finn’s method here o got the same exact result as you. Car starts briefly then dies and throws an error. What solved your issue? Thanks !
A test done in autozone came with the diagnosis of cylinder 3 and 4 coils are misfiring but when I did the test according to your video, all four seems to be bas as the RPMs in all four test were the same, above 1,050 Is it possible all 4 are bad? Did I miss something on the video?
Hi peter, i have a toyota spacia, so instead of single coils.. ive got 2.. 1 for 2 sparks. Would i try the same thing as above to find which coil of the two is faulty? Thank you
I saw the same video. Mine have 4 prongs as well. I tested them in the same manner. For instance: 1&2,1&3,1&4 2&3,2&4 3&4 All coils gave basically same readings. But i didn't realize when the coils are disconnected I was only testing for resistance. Turned out to be bad coil. Replaced it and all 4 spark plugs. Ran great for a day, now its worse. Good luck!
Hi I went to autozone to do a check engine light test and they told me that there is a misfire in ignition coil 4. I followed this video on the instructions and replaced the ignition coil to my furthest left (which I assume is ignition coil 4). My check engine light is still there even though I replaced the old ignition coil with the new one. Did I replace the wrong one? The car runs fine, but I am just curious if I did it correctly.
Peter, I had codes P0352 and P0354 on my 2010 Corolla. All Spark plugs, boots, and cylinder 4 coil pack are new. The codes reappeared with a slight shake that is not constant. Dealership tried to sell me an "intake cleaning" for $250, which I declined. Before I pay someone is there something else to check? If I disconnect each coil you see RPM loss, so I feel like I'm chasing a ghost. Thanks!
Mr Peter. I copied u after I watched this video clip. we have exactly same cars. I take first coil wire plug off. Then turn on engine, it failed totally . Then i did one after another with same result. The engine only be able to turn on with plug in all 4 coils. Base on my experiment, don't u think I have bad coil pack?
You may have 2 coils out. Buy one new coil. Measure RPM with original coils. According to this video 1 coil out =1050 rpm and 2 coils out =950 RPM. Mark 1,2,3,4 on old coil tops with marker. Replace coil 1 with new one and see if revs go up. If so, coil 1 bad. If not, coil 1 good so replace coil 2 with 1 and see if revs go up. If so coil 2 bad. If not, 2 is good so replace coil 3 with 2. Repeat with 3 into 4. If you find a bad one (example coil 2) and the engine is goes from 950 rpm to 1050 rpm and is still rough, get a second new coil and swap out the remaining coils (3 then 4 in this example). If no change with coil swap out, it is another problem and save coil 4 as spare.

Hello Peter, is this test reliable enough? What about different behaviour of coils under other circumstances, i.e. faulty coil appears to be OK on idle RPM and faulty under the load ? I do have a problem with my 2007 Corolla 1.4VVTI. It seems to have power lag between 2000-3000 rpm and then it gets power kick and accelerates linear as this atmospheric engine should, or it's accelerating hard and at 5000rpm it gets power lag for 1 sec and then continues to accelerate. From time to time I'm trying to accelerate, revs are increasing but there is no power.. I have tried to clean MAF, there are no DTC codes... Is it caused by coils or I should to try something else. Thank you in advance for your ideas. PS: great video.

Help I can't unplug the wire

For more convenience you can measure with a infrared thermometer each exhaust tube...The one who has lower temperature has the faulty coil....
Gracias Peter, muy buen tutorial me gustó , saludos desde Sonora México

Awesome video Mr. Finn, I learned something new today. Thanks for taking your time and doing this video.
You are Welcome Sir. :-)
Had my car parked for months no time and not knowing what to do... thanks for this video!
Glad it helped!

Thanks for comment 😀👍
Thank you for making this! This is a very good video!
Thank You, Great to hear. :-)
I love your videos & love your accent .... so cool.
Wow, thank you! 👍 😀
I have a nice evening, thanks! A separate thanks to your attention of a safety work with HV coils. )
Thanks

Great video. Does it matter if engines is wormed or could ?
Not at all
Legend!
Thanks for the video
You bet!
having an issue where the coil goes out often, any sugesstions? coil 1 keeps going out i replaced the whole pack recently on this same car.
Ok. How it goes out...?
@@PeterFinnTheCarDoctor well the head gasket is the newest issue hoping it resolves the burn out problem.
@@PeterFinnTheCarDoctor the engine will misfire then the cpu reads coil 1 misfire replaced it 3 times in 1 month and all 4 the 1st time
FYI these cars are known for blowing coils.. I keep spares around.
Yes, European made coils are weak, Made in Spain.
You are amazing. Thank you so much!
You're so welcome!
U should change the title How to replace instead How to repair... I though u can repair the broken coil.
Thank You for feedback. :-)
OokTiaopi...that was the only reason I clicked on this video too. I was amazed to think that one could actually repair a coil rather than replace it.
You saved me time
Do you have to change out the spark plug as well?
Yes
I have a question. I replaced the rubber boots that go over the spark plugs and the kit came with those little springs that contact the top of the plug. How do you remove/replace those? I tried unscrewing them, but they just spin freely in there. I'd like to try replacing the springs before I buy new coils. Thanks!
Hello Jonas.
You don't need to replace the springs, because you have the car named Toyota 😀😀 Have a nice weekend

Yes, absolutely

is this procedure just for Toyota or for all cars???
Yes
Good replacement. But the idle rpm seems very high
Hey Peter, when I try this unplugging 1 ignition coil, my car wont run it starts but shuts off as soon as it starts.. when I have them all plugged in my car works but rough
Maybe some other coil is Bad too
definitely just replace all the coils at that point my friend

Is it possible all 4 are bad? Did I miss something on the video?
Is it safe to do this with the battery connected? I saw another video where he unhooked it first.
Unhook is the Best 😀👍
Thank you. very good video
Thank you too
Very informative great video I wish you all the best with your channel bro
Thanks Sir. 👍
Hi peter, i have a toyota spacia, so instead of single coils.. ive got 2.. 1 for 2 sparks. Would i try the same thing as above to find which coil of the two is faulty? Thank you
Yes
Peter is there a way to test a four prong coil with a meter. I saw your video for a three prong but I need four prong for my Camry
Ok, I will do new video
Peter thank you so much for responding to my comment you are a blessing
I saw the same video. Mine have 4 prongs as well. I tested them in the same manner. For instance:
1&2,1&3,1&4

I changed the coil that seemed to have gone bad,and my car is running fine but the check engine light and the trac off light is still on.
Ok

I went to autozone to do a check engine light test and they told me that there is
a misfire in ignition coil 4.
I followed this video on the instructions and replaced the ignition coil to my furthest left
(which I assume is ignition coil 4).

Did I replace the wrong one?
The car runs fine, but I am just curious if I did it correctly.
What happened with this
@@crackerjackB It's running fine now, I just had to get an obd scanner to remove the check engine light after I replace the bad one.
Thanks for comment. I appreciate 👍😃
Where is the fourth cylinder? Was your problem the fourth cylinder?
Fourth cylinder is OK. Like First cylinder. :-)
Good job 👌
Thanks 😅
nice video thank you
Thanks, Your comment is great. :-)

Is it the same method on a 99 Corolla ?
Yes

Can you Convert Coil on to 4afe?
Maybe 👍
nice done!!! thank you
Thanks for comment. :-)
Thanks! My question is if you have to disconnect the battery before changing a coil?
+Vlad Gazi Yes, it is always good to disconnect battery.
Not necessary to disconnect the coils
Pitääkö kone olla lämmin kun tekee tuon testin.?

Welcome
Hello my engine didnt want to start when i tried this
Let's fix Your issue. 👍
i thought i would learn how to repair it and save £50 oh well
Ok
Incorrect title. You should name it as replacement. Not repair
Hello. Nice you noticed my mistake. I will fix it soon.
thank you

hey +volkovski, were you able to find the problem? i have the exact same issue you have.
