09 Toyota Corolla Misfire Fix 1.8 Coil and Spark Plug Replacement 

I don’t know how much money you just saved me, but I can tell you I just had the easiest time diagnosing and correcting the issue I’ve almost ever had. She’s purring like a cat! Thanks much

Hey update. I did this exact check and sure enough I had a bad coil. I bought a new Denso coil online from some Toyota OEM place and I decided to change all spark plugs too with new iridiums. Perfect video to help me do this myself. I REALLY appreciate it man. 180,000 miles and running strong again.

One of the BEST troubleshooting videos I ever seen. I fixed mine myself thanks to you.

Went to Autozone this morning and those codes came up so I made an appointment with Toyota this morning to look at my car next week. Then I found your video and went back to autozone and bought my coils and spark plugs. Even bought my own code machine. Will replace them all tomorrow morning and then will cancel Toyota appointment. I most likely paid for the parts what they would have charged for just labor. Thanks

Great video, Toyota wanted $422 to replace the bad coil, going to subscribe so that I can check out other vids. Thanks

I've literally just finished fixing my Corolla using this video, thank you so much 🙏🏻

207,000 miles and just had 2 coils go litteraly a few hours apart. Felt it go from 4 to 3 to 2 cylinders. Still ran though lol. Took a few minutes to hit speed, and hills were no fun. Anyway, your video helped me diagnose which coils were bad. Thank you sir! 0h more side note, Car is running great however driving around for A-day on 2 cylinders has now seemed to have caused an o2 sensor to go bad. Ill replace that soon.

Exceptional learning moment here. I bet I got an ignition coil pack problem. Seems to have same exact issues as this car. Mines a 2009 with 180,000 miles. Just happened today. All the symptoms are as described. Now I know how to check! PS - never changed any of these and also never changed plugs before ever.

My wife’s Corolla is idling like a Harley. I got codes for misfires in 3 and 4 and a bad crank shaft sensor. I switched out the sensors and it helped some but still not good. I was going to just change the plugs but I’ll have to try switching up the coils to see if the codes change first and see if I need new coils too. 👍

This was a sick video man! The POV of how you do things is really awesome!

Excellent video. My 09 Corolla has 400k and never had a coil replaced. It’s in the shop but I’m almost positive new spark plugs and a coil is the issue. Thank for the video.

Same exact issue on my daughter's 09 corolla, P0302. I replaced all 4 coils and all the plugs, thanks for the video, saved me some time wrenching on her car!

Great vid,this is my second time having this problem witk my 09 Toyota it's been a month since they changed #3 coil,plus my car is over 200,000 miles

Great video and instructions. I was able to fix my 2006 Corolla. It had the same issue. #2 coil had to be replaced. Once, again thank you for helping others save a little money.

I had my coils replaced in October, now it's doing the same thing. I think I will change out the spark plugs and recheck the coils. Thanks.

Just got a p0302 on my Corolla. Your video was well done and informative. Thanks!

Hey bro, thank you very much for your video, I have the same reading on my car but thanks GOD i saw your video. Now all i have to do is order the ignition coil. Thank you and my gratitude to you.

Very good video. Straight to the point instead of beating around the bush.

Thank you for the video very informative and not drawn out.

I LOVE you! I have confidence that I can fix this on my own. 😃🙏🏾💕

Thank you for all the help!!! Had exactly the same issue. #2 coil pack r&r runs great again. Again thank you.

Thanks for making this video. Save me hundreds. God bless👍🏻👍🏻👍🏻

Nice my #3 coil was bad went to autozone bought the coil ordered a set online all 4 for the same price as 1 in autozone. Replaced all new coils once they arrived and returned autozones temporary coil i borrowed 😂.

Well demonstrated and simple explained. Thank you Fixitphillip!

You saved me over 500.00 bucks. Thank you!

You made that look easy enough for me to fix. 😂 thank you!

GOOD VIDEO GREAT JOB I DID SAME THINK. BECAUSE GOT THE SAME PROBLEM WITH TOYOTA COROLLA THANKS..MERRY CHRISTMAS ........

I purchased a special socket. One magnetic and one with a slight friction grab. I like you magnetic screwdriver too.

Thank you man i just put in a new fue injecter, and piston 2 still mist fire , and yes injector was bad i put a new 1 next plugs and check coils, thanks one more time nice video information keep up the good work and information.

Really appreciate the video! I’ve got a cylinder one misfire that isn’t resolved by replacing the coil pack and I’ve had a rough running motor for a long time with no codes. I can’t for the life of me figure out what could be causing my cylinder one misfire now, any guidance?

I love you brother, it helped me alot today. My car's Third was the culprit lol

My car has exactly the same issue, thanks legend.

Outstanding job showing this video. I like what u did with the testing.

love your videos man stright to the point

Thanks for the diagnosing help, I'm sure this will help me replace my coils!

I really liked your video. In my opinion is very well explained, especially when you mentioned the parts already changed. Thanks.😊✌️

Wow... simple and straightforward, ❤

I have a 2009 corolla with a cylinder 1 misfire. Tried to pull the coil pack and it was stuck so I used a hammer and long extension to break it loose, when I pulled the coil pack out it was rusty. Any idea why or how moisture gets into the port

Hey Philip Great Video! Just wondering what OBD tool you use for diagnostics? OR if you could any reviews on the OBD Diagnostic Toolkit, that would be awesome too! Keep up the awesome videos!

Heard about your channel on Eric O’s what’s up wednesday video, keep up the good work I hope your channel gets big!

Good video, explained well! I noticed the roosters crowing and the beautiful view on the test drive! Are you on Kaua’i?

Thanks , very useful video , very practical

Definitely helped me. Subscribed!

Very instructive. Very well done.

Hi did this proceedure all ok for two months and im back with the old problems again on 2009 toyota corolla 1.8 LIT.

Thank you very much brother you are a master of mechanic 🖖🖖🖖

Thanks that's a big help I did it

Great vídeo sir thank you much.

Mine was cylinder 1 I did the exact same thing ran fine for about a week and a half then the problem came back could it be a faulty coil? Any recommendations?

Amazon sells those parts for $20 each, are these any good? the auto stores sell them for $80 each.

wow you have just solved my problem man

I'm having a issue with coils right now on 2003 Corolla. My in law changed the plugs and he was putting the coil back in and apparently he dropped a piece of plastic from the socket packet he jus bought. I didn't notice bcuz he started on his own. Today i looked in there and plastic was not allowing the boot to go over, so like a genius he holds it down and tightens it. I think that damaged my coil bcuz car was running fine before, now it's misfiring, so im waiting on my set of coils to come in. Jus gonna change them all i think they are manufactured part and this car has nearly 300,000 miles on it.

Thanks for your video. It helped alot

Thank you 👌🏽💫

How much tight should the spark plugs go? 18ft.lbs, 15ft.lbs, 13 ft.lbs or just 90 degrees more of ratcheting after you can't no more with hand?

Thanks for this great video

.Thank you FixitPhilip. I notice that you didn't use anti seize compound on the spark plug threads nor dielectric grease on the coil boot. Do you think theses would be helpful?

Thank you for you helps

Gracias amigo por el video

Great , thank you so much.

I have the exact samw car with the exact same issues. My car sounds exactly like this.

Great video thank you

Every ignition coil has a number. I mixed mine now I don't know the correct order which ignition goes to which spark plug. Toyota corolla VVT I 1.8 petrol

Nice video .. big help

damn my #2 coil is misfiring too, crazy that its the same one lol (although 25% chance is pretty high i guess)

Thank you so much!

Question I just got all of my plugs an coil put in an Still giving me same code you think it's the wire in the coirl

IF YOU ARE ACCELLERATING SLOWS DOWN A BIT PRESS GAS AGAIN AND VEHICLE MAKES A SUDDEN JUMP ... IS THAT A MISFIRE.... HELP PZ....

Thanks for a great troubleshooting vide. I also got P0302 code in my corolla. Anyone please advise me if I did this right. I swapped the coil 1 with coil 2 and start the engine - still same code. So I think the coil is good but spark plug in 2 is bad. Anyway I ordered new spark plugs and waiting for delivery. Will update after I got the spark plugs replaced.

Hey boss. If one coil goes bad do you recommend changing them all?

No change when swapping coils or with a new coil, car runs smooth for a couple hundred feet of driving then misfire comes back, shut it off turning back on car runs good for a short time them misfire is back, bad fuel injector or possibly pcm is shutting off power to the injector? A couple of weeks ago multi cylinder misfire came up, replaced all coils was fine for a couple of weeks until now, 236,000 miles on car. There's another video on here where a shop replaced the plugs coils maybe injectors and the pcm for a similiar issue, it was ultimately diagnosed as a dead cylinder and the engine had to be replaced. I'm trying to Help my neighbor by fixing her car, I don't have a scan tool however just an actron code reader, I'm stumped.

I changed the coil and spark plug on my 10 Corolla 1.8 on cylinder 2. I can still hear a misfire but the code does not show up on my ObD11. What do you think it is?

What is you switched sparks and coils and keep getting miss fire on #1

So coil and spark plug replaced but still getting Po301 on 2014 Corolla with 111k miles... Any idea? I reset the Odb runs well for about 3 miles then light comes back on

Great video!

I have a p0300 error code but I’ve changed coils plugs fuel injector and my car runs clean but the code comes up every now and again why

Hi I have 2006 Corolla car suddenly shake and get code p0351 I replace coil of cylinder 1 and 4 plugs and it doesn’t fixed. I checked wires and don’t see a dommage. What can it be?

here from south main!

What plug are you using for new ones in this 2009 1.8

Wondering why my Corolla dies when I unplug cylinder 1or2

I changed all my spark plugs and ignition coil #4 was misfiring I changed it but the check engine light still comes one about #4

You are good 👍 God bless!!!!!

Great work man

How common are multiple misfires caused by an intake gasket?

Can you list the tools used please

What sort of power tool is that?

If you didn’t have the coil specific code, and only had the p0302 code, what would have thought is the most likely culprit?

So easy I will check my car

Hey buddy. Its there a way you can help me out. Look i took my toyota corolla 09 1.8 liter to O'Reilly so they put the scanner and came up that the cylinder 4 has a misfire. Right!!! So i bought a new coil and all 4 sparkplugs and its keep appearing the same #4 cylinder so what can't i do.

I change my cylinder 2 misfire and again came up

I’ve changed all my coils and spark plugs, but still, there’s a misfire in cylinder one. What gives?

And may I add that maybe you dont need to spend money on a scanner if you check each individual coil like he did.

I get hungry see the pizza

Bro this happened to me at 169 thousands miles tooooo

Hey I have a question is a torque rench needed or no?

@fixitphilip. Please how possible can you help me get those original spark plugs and coil because am going through same experience.. would have brought my vehicle to you but am far away in west Africa. Please help me🙏 Please help me🙏🙏 I will pay 💰 for the package

Replaced my coil pack and now my car won’t start. Radio won’t even turn on. Did I blow a fuse? Or is a bad coil?

Do you have to gap the NGK laser Iridium plugs ?

Replaced all spark plugs all coils no power

Is it the firing order or just go across 1234
