Really loved how direct and easy he put this information I had a hunch on it being my coils what led me here but the way he put the info just about validated what i'm experiencing thanks bro!
watch in 1.5x trust me
lol alrrady had it before seeing your comment. youre so right
lol it makes him talk normal not like a slow stoner
1.25 is perfect
I feel like it should have been obvious but you are the only person to mention the gas smell because of bad ignition coil. I was racking my brain trying to figure out if it was a clogged fuel injector or the coil but that last comment seals the deal hopefully replacing the coil fixes the problem thanks!!
You can tell he really enjoys this stuff. I know nothing about cars so I'm glad you are here..lol My car started with the Trac Off light then the Check Engine light came on. I had two readings of cylinder misfire. Yep its hard to accelerate now. This is definitely my problem.
OMG thank you for being so "to the point" last thing I wanna hear is a bunch of no-need BS. this was beautiful and helped me know my coils were bad. God bless
You're the best bro, for many reasons, here's a prime example I've watched other videos today pertaining to bad ignition coils and how to troubleshoot them properly and not once has anybody said to simply watch for the rough idle and simply change out each coil pack until the rough idle stops lol, everybody was using multimeters and 20 minute videos blah blah blah you're the best man thank you
Brief and to the point - perfect! Subscribed for that one thousand horsepower!
Haha your awesome!
Accurate, right down to the smell of gas. Thanks for confirming my suspicions!
i started to smell gas coming from my exhaust
I subscribed, but my 2003 Acura TL only saw a 950hp increase. 😂Thanks for the simple yet informative video.

Love how detailed this video is!!! Thank you ❤️
Very nice, thank you!
Had this happened to me while on the freeway, going 100 km/h. Sudden loss of power and excessive shaking. Decided to keep driving to the garage (~10km) where they concluded it was indeed the ignition coil (as i suspected). They had to order the part, but once they had it, it was fixed in 20 minutes. Including parts and work, it cost me 165 euro's. It sucks, but compared to other car trouble, this was nothing :).
I'm afraid they ripped you off as it's a very simple fix, should have been about 70 euros
@@stevenmack9948 and the time for diagnosis is for free? The part itself I'd assume they take 50-60€ for. Installation is really done within 10-15 min, but idk how easy diagnosis is to find the right, if it's just giving an error code for the one to change.
@@l3138 I work as mobile breakdown in UK & could diagnose that in 5 mins & show the member how to fix themselves, you usually only need a 10mm socket, not really a garage job
So it's not convertor
Not always parts can cause problems check ground wires may be broken don’t have to spend money on parts unless it needs to be replaced so
Sounds good I just ordered a new set. I'll check it out as soon as they come in. Thanks 💯🏁🏁🏁
Need another one, these are outstanding.

One problem that is not often mentioned in the many videos I've watched on Ford / Mercury ignition problems. If you replace plugs and coils and other parts, and find your engine light still comes on after a while, or shortly after replacing parts, the real problem is that the main computer needs to be reprogrammed. I spent about 800 dollars replacing plugs and coils twice, mechanics replacing parts, etc. all which did not solve the problem. You may also notice the car jerks when you accelerate, as though you have a transmission problem. The real problem is not the transmission. The main computer has to be reprogrammed. Another symptom is the air conditioner compressor will shut down; you will not have air conditioning. That is to protect the AC compressor. Once you have the main computer reprogrammed, the AC compressor will work. I went to 6 different Ford dealers in Miami / Ft. Lauderdale, and none of the six mentioned a thing about reprogramming the main computer. I was told by several dealers, not knowing about the main computer at that time, that "there's nothing you can do."
One Ford dealer had the car a full day, and said I might have to replace the main computer, and that they cant do that , because Ford no longer carries them.
I finally found a Ford dealership (Pines Ford) who said they could reprogram the main computer. Regular scanners can't reprogram your computer. It requires a bi-directional scanner, a Ford subscription for the scanner, and someone who knows the procedure required to reprogram. For that reason, IMO, it's best to take it to a Ford dealer who can reprogram the computer, and they can also check to make sure your plugs and coils are all functioning correctly. They can also check for vacuum leaks, vacuum hoses that may need replacing, bad coil connectors, etc. Not cheap, but better than paying a mechanic to replace parts that won't fix the problem.
Bro this comment thank u man 😃
Disconnect your battery and let the negative and positive terminal lock together for about 20 minutes then connect back to battery. That will reprogram your car.
@@BlackWhite-ru8gm Not saying that will work. What vehicle have you tried that on ? Here's what we know for sure about scanners. The typical low priced scanners, or any NON bidirectional scanner can't be used to reprogram your computer. At best these scanners can tell you if a particular cylinder is misfiring. The most these scanners can do is shut off the engine light, TEMPORARILY. The light will come on again eventually, as soon as the main computer senses that the car is misfiring.
None of these scanners can sense a bad wire, or if they do, it may be a bad connection or connector on a particular cylinder. The scanner doesn't say "Faulty connector, Faulty wire," etc.
The few truly qualified Ford dealers that will reprogram a computer, Like Pines Ford in Hollywood, FL,
have the factory authorized scanners, codes, generally parts and wire connectors, to fully assess ignition problems. Expensive yes, but far less than having a general mechanic replace lots of stuff, and still not be able to reprogram you main computer. If you go to any Ford dealer that tells you your main computer can't be reprogrammed, or that the main computer needs to be replaced, then you may want to find another dealer. Unless someone has damaged the main computer in some way, they generally should be reprogram-able.
@@BlackWhite-ru8gm what do you mean by lock together??
@@willardferguson7818 connect together i think (like shorting the circuit without the battery idk)
Does this affect oil pressure too? I changed my oil pressure sensor and when I was reassembling everything I broke and ignition coil connector terminal. I started the jeep just to move it out of my cousins garage while I wait for a connector pigtail to arrive, it obviously hesitated to start and once it some dash lights came one. Check engine, the red lightning bolt light and the oil lamp light.
Helpful and right to the point with no bs filler talk. (the like and subscribe bit was earned and justified)
Awesome video. This is the EXACT problem with my vehicle. The smell of gas and a rough idle. Purchased 6 new spark plugs, a coil, and gasket. Putting them on bright and early tomorrow.
Did it work?
I have a misfire but without any code or warning lights on dash? Tsi 1.4
was on my way home from work and barely made it, luckily my mechanic makes midnight repair trips for me. second time in a month this issue occurred. don't smell gas, but a foul gross stench. acceleration is difficult- can't maintain over 40 pushing the max, very rough idle. thanks for the video! went and got all new spark plugs and coil packs today!
Dang! You have a Mechanic that gives midnight repairs?! You are special and you know it! Lol. That's awesome! You definitely need to send him a gift card showing appreciation.
And how’s it running now
@@gabegarcia7779 running way better. still running rough but it needs more work done.

Midnight repairs trips huh? You might repay him in some time of way..
Will small break on the top plastic part ring around the epoxy is fatal and need a new one eventhough it still work? Mine have a break/crack on top when I tried to remove it by a tool. The motor runs fine so should I have to waste money to buy a new coil?
is standard blue streak ok to use on pontiac grand prix. they have o.e.m. ones.
Wow tnx straight to the point no bs for 1 hrs
Very, very, very helpful. Thank you!
Would you recommend dielectric grease on the coil connectors? Thanks, good and informative.
Thank you for this. When you said the smell of gas i realized this is what is probably causing my engine to misfire. I’ve been smelling gas for the past week and didn’t think much of it. I got my resonators removed today and the problem started happening. Hopefully it’s just coincidence and the ignition coil is what I need to replace.
Comment what it is
@@MuscleCarMike piece comes in tomorrow, will keep you posted
Was it your Coils?
@@talamantezfamily3123 yes it was. Car runs great now
Thanks Bro appreciate it 🙏
Thank you. I know nothing about auto repair but now at least I know what is wrong with my daughter's Ford F-150. Very well explained.
Thank you! Be mindful that other engine components can cause similar symptoms so make sure to do research and test carefully. Best of luck!
Thank you. Simple and to the point!
Thank you for being brief & systematic in your description.
I have rough idling on my Lexus gs300 no warning light on the dash…? Any ideas?
Spark plugs are new clean throttle airflow sensor etc.
I got a used 2011 ford f150 ecoboost and i had replaced spark plugs and a 02 sensor & it would stutter when i tried to pass someone or floored it. And no check engine light would stay on but would blink then go away. I really didn’t want to spend on a new fuel pump so i further investigated, what i did noticed was residue on the tail pipe like carbon build up at the tip. Meaning running to lean or to rich. Boom changed the Coil packs and it worked like a dream. Got me some msd coil packs fpr $365. My opinion is spend $25 more for the msd than the duralast brands and the motorcraft are even more expensive might i add they the same as denso. I also have a oil catch can to protect the intake manifold and turbos from blow by oil. 😎😎😎😎😎
Thank you for simple advice
This was really well explained and written!!!!!!!!!!!!
I got my ngks spark plugs in. In the morning I'll be doin this looks easy and I'm glad I did my research💯🤝🏾
Good info, thank you!
@EasyAutoFix i have a '91 Chevy Caprice Station Wagon = no gas smell, but same symptoms = why when my mechanic replaced the ignition module, it improved slightly imo. QUESTION: would bad ignition coil lend to low (15psi) pressure in engine? Another nearby mechanic shop says he believes it's the floating valves & wants to rebuild/replace engine🙃 The issue came out of the clear blue: car ran fine, came out of a store & was barely able to drive to mechanic - determined to get it running = great car & sentimental😳🙏
So my 97 civic is randomly dropping power while driving but then (within a few seconds) it pops back on and continues driving. The couple times it didn't come back on I pulled over and restarted the car. Usually starts within 1-2 attempts. Does this sound like ignition coil? I also idle super low at stop lights and it dies on me sometimes. I even adjusted the timing of the distributor all the way up and it still barely idles right above 0 RPM.
Hello! Thank you for the video. We changed both the spark plugs and the coils yet it doesn’t seem to have fixed the problems. I am experiencing all said symptoms as well as bad gas mileage. Where can I look at next?
Thank you so much when I heard you say you can smell gas I was like oh that’s what’s going on this is a great help thanks
Well my 15 Ford Fusion SE 2.5 L is stalling a lil. Tried the switching the cylinder 1 plug to cylinder 2 and vice versa. Still have code P0301 the cylinder 1 misfiring. So it’s not the plugs. Going do the coils next. Do the same switch them around. If no change the same thing code P0301 then it’s the injector. Right ? Any input be appreciated
straight forward explanation. I recently had this issue but instead of fixing the ignition coil, i changed my spark plugs (which is almost due by the way). not long after the spark plugs replacement, my car was still jerking on low RPM (1,000 - 1,500). after inspection at a proper workshop, they discovered that 2 out of 4 ignition coils were not working properly. Now waiting for the parts to be delivered and hopefuly this will solve the jerking issues.
Thank you. 2 out of 4 ignition coils is a definite cause to the engine not working properly! It should solve the issue. Best of luck!
@@easyautofix yeah, will revert once the replacement is done. On another note, is it worth it to purchase your own OBD device to scan error codes? Just wondering.
@@ernestjion8006 Personally yes for two reasons. 1. Could be an easy fix and if you got time to work on your car, it could save you tons of money.
2. If you want to have an idea of what’s wrong with your car before you go into a mechanic it’s good for that reason as well.
It’s an investment in knowledge + application= power.
@@easyautofix much thanks for the reply. WIll definitely look into the pros and cons of it. Anyways keep up the good work mate. Channel like yours is a huge help for idiot like me. Subscribed!
@@ernestjion8006 Not an idiot, just haven’t been exposed to it that’s all. Thank you, I appreciate you 🙏🏼
This was what was wrong with my car, but this video talks about the symptoms as if they’ll happen at least a few days before your car breaks down. My car only had low fuel economy before the drive in which it broke down, and only began occasional vibrations about 10 minutes before it broke down(I thought it was a wheel problem). Stopped at a red light and could barely accelerate and car began shaking badly so I pulled over. It’s weird because usually I’m hypersensitive to anything wrong with my car and it’s noises/movements.
My cars got the exact same problem. Can I ask what car you have?
that's just how your car behaves his diagnosis is spot on sir
Can it be catalytic converter to
Same problem also
Bad ignition plus pressure loss maybe. How since you’ve changed any gaskets
Soo you need a good battery for your coils to run good right? Or what does a battery do in a car like what’s it’s purpose?
Hi Bro whats up? I am from Dhaka, Bangladesh. Hope you are doing well. My problem is after started the car engine, race just increased and it is fluctuated. Once i pulled my ignitions coil from any of, the engine race came down and smoother. But once i put the ignition coil in the engine race goes high. Pls advise.
Good information. Thanks!
my 15’ dodge dart is slow to pick up speed fast enough. Do you think I have a ignition coil issue?
Great video bro. Precise/Straight to the point 💯
I appreciate you
Thanks…!
Well taught 😎
my car (when its warmed up) makes a jerk when pressing gas pedal on low gears/low rpm. Does that have anythjng to do with ignition coil? pls help
Hi, i have a vw jetta 2005 and suddenly the engine start shaking and a check engine appeared. It has misfire on all 5 cilinders. Is it possible that all 5 ingition coils are bad at the same time???
Great video I like how you slid that (like) comment into the fix salutation 👍
Very nice, thank you!
When changing my spark plugs do you think it’ll be a good idea to change the ignition coil?
Is it possible no code will come up? My 12 Sentra runs rough only on drive when idling other than that it runs smooth. Changed motor mounts, belt pulley, and a complete tune up. Coils are all original 130K miles no code yet.
My Jeep started to Crackle a shit ton when I step on it and idk what it could be ima change the spark plugs first
Great job. Thanks
Change your smoke detector battery
If I replace the plugs and ignition coils in my car, should I also replace the wiring harness that clips onto the ignition coils?
You dont have to necessarily unless there fried
Another good one! Thanks.
Awesome video! TY
Very nice, thank you!
This was Rt on time! Gratitude 🙏🏾
Can you describe how to troubleshoot a coil on a farm tractor ? Thanks
Sounds good my bro ...thanks
Question, I see a little rubber around the sparkplug, i is preventing the sparkplug tool from wrapping around it to get it out. Is there a way to get it out and remove this circular rubber that seems out of place? The rest of the spark plugs and coils don't have this rubber and there is easy access.
The rubber is probably from the spark plug socket that slipped off when the spark plug was replaced previously since it is only on one spark plug. Use a small pick to remove/lift out or remove your spark plug socket rubber insert and see if your socket fits over the spark plug.
My truck does the rough idling. Thank you. No check engine light though.
What causes spark to jump out of the coil hole. Only #2 does it and the other three don’t. Cylinder 2 is misfiring . When you pull out the plug wire, spark jumps out of the coil hole. Help. Installed new coil and still have the same problem. Help
Thank you for sharing
Great video! Thanks for sharing.
I appreciate you, thanks!
How do you know which ignition coil to get?
It is universal?
Thanks bro. Fixed my issue
Nice video .Subscribed .Ps I had an lpg car years ago and it cooked coil packs .Misfiring and caused the engine temp to go up but always limped home.😅
What if I have those symptoms but the smell of gas? Would it still be the ignition coil?
My 07 Lincoln Navigator has lost acceleration but has no check engine light, also making a ticking noise, could this be the prob?
No acceleration ? Check your throttle body
Ticking noise ? HOPEFULLY NOT engine knock... Which could be the end of the motor at some point , once the knock starts it doesn’t go away
Great channel! So I have a question for you. My 2018 Chevy Silverado from time to time check engine light will come on and my traction control light as well. My truck runs rough and has a hard time shifting. Then eventually the light starts to blink. I check the code 0301 and 0600 ish codes come up but by the time I get it to the dealer the light goes out truck returns to normal and the codes disappear. It literally shows no codes!
It’s done this 5 time now since I’ve owned the truck. And ideas what this could be? Thank you 🙏
In regards to the P0301 meaning cylinder 1 is misfiring. One of the most common causes for that could be a bad ignition coil,spark plug or fuel injector for cylinder 1. As far as the P0600 code meaning the Engine control module having communication errors could be due to low battery voltage, a bad ECM, or a lose connection/wires on the ecm or maybe in need of an update. P0600 code can also be the reason why you have a p0301 code as the ecm could not be working correctly. Hope this helps. Best of luck!
@@easyautofix I understand thank you
i got cylinder 4 misfire. i just changed the sparks plugs as it's going onto 20,000 miles which is probably the base range for generic parts on a 2017 Hyundai elantra. the engine light went off for a few days. now it's on again. i don't think it;s the ignition coil as it's not even 20,000 miles yet. maybe if i check the wires connecting? i need an oil change very badly. i but i don't see how that can cause misfiring.
I appreciate the help my boy, you really helping me narrow down my engine issue 💚💯
and i appreciate you!
Great video ty
I fixed the biggest problem but couldn't handle the extra horsepower it unlocked and I totaled my car.. totally worth it!
My dodge is doing this it will shut off not lose power but shuts off engine wise when I am slowing down and jerks and lower rpm when I’m driving at a steady speed did you figure out what’s causing it no check engine light either
Change of engine tone is also a very important one
You are soo kind bless you 💖✨
Very helpful thank you very much
Thank you!
No bro, you're the greatest. Thanks!
subscribed! i want that more horse power! gonna test drive it now
Thanks a lot 👏🏿
So when I start the car, it idle low and sometimes dies, fine when you’re driving and have gas. At idle or when going into reverse with no gas, it sometimes dies. What you think? Spark? Also mpg is way down, like 9
Will it affect the battery as well ?
Awesome content
Do bad ignition coils cause the car to drop into neutral from drive when cold idling? No issues once the car is warm. I've already changed the air filter and cleaned the EGR valve
Please check your transmission fluid and make sure 1) you have enough fluid on the dipstick 2) that the fluid doesn’t look contaminated. The ignition coils,air filter, or EGR doesn’t have much to do with your problem but it is still a good thing you have those out of the way now ! Good luck please let me know if this helps!
Good job
Can you have this with no check engine light?
Awesome video! I'm currently in the process of replacing my ignition coils and spark plugs.
Sorry to be random but does your car actually move?
Mine doesn’t move at all so I’d presume I need more than just one ignition coil 🥲
If i have PO350 what can be done?
I liked and subscribed n just saying. I an still here on the side of the road w/o my car starting. But thank you for the detailed slow video
