Thank you for your video! Newbie here... Got a 4-cylinder misfire code and panicked. Watched this video, went to the auto parts store with 5 minutes left. They had one more Cylinder Coil left for my car. Yada Yada Yada .. Kids get presents this year lol. Thanks again.
Well if he wasn't going to do it right then he was smart because if youndont don't right then but leave it off. You might lose it before you do the job or even lose a nut or anything. If I take anything off i put it back on unless I'm doing the replacement right then if not always put the thing back together with all nits secured because if bot by the time you do it and then go back you can't finrmd the civet or the nits that fasten it down. But that's me do as you do but when you lose it or fasteners you'll be in posdobltmote trouble than before
@@jevonlemmermann4576I’m not saying it’s a big deal or anything but it’s literally two bolts, if you needed help with that then I’d say you don’t need to be watching a video like this anyway lol
I need your help please, I have a 2012 jeep patriot I been having a cylinder #4 issues, I install new spark plugs and i switch coils and injectors to differents positions and when I disconnect coils and injectors # 1,2 and 3 the iddle changes and with the #4 nothing change, I did a compression and #4=190 #3=160 #2=190 #1=180 any ideas? Thanks
@@Singleturbocobra Thank you. I did what you said and swapped out the ignition coil to the 3rd cylinder. It was indeed the problem. I appreciate your helpful video!
I have a 2014 chevy cruze .My car engine shake under red light but runs smooth.I took it to a mechanic shop i m told the Cylinder 4 is weak but they refuse to fix it they want me to replace the whole engine.
Hi, my car lost power becasue of this and got it diagnosed at my local garage and they said the spark plugs are fine and they even changed them around and it was still number 4. They said it was the ECU, i went and started it up and let it idle for over 5 min and everything was fine. I didn't drive it as it failed it's MOT anyways but that's beside the point. So, what might it be as i dont want to spend loads of money and fiat quoted me nearly 1K for part and labour all that BS
And what happens if you switch the bad coil and put a new one. And keeps appearing the same code p0304?? Little help... you think i have to replace the fuel injector #4??
I have the same issue my 2012 jeep patriot have a code p0304 for misfire on cylinder #4 and put new spark plugs and same code, a swap the coil and injector to #1 and I still have the same code for the #4 any ideas?
Good day, thank you for the video. I was wondering if you happened to know, what is the difference between check engine codes p0304 and p0304p? My 2004 base model Pontiac Vibe has both of these error codes (as well as p0354, p0354p and p0420), even after swapping ignition coils and replacing spark plugs. So the problem has remained on cylinder 4... so not the ignition coil or spark plugs. When I unclip #4 wiring (with the vehicle running), nothing changes. When I unclip the other 3, one at a time, the engine idle clearly changes and decreases as expected. I wonder if this indicates a fault in the wiring, or could it still be the fuel injector or something else... I appreciate your video. Cheers! Laura
To my knowledge there is no difference between the P0304 and the P0304p. As for the P0354 that indicates you may have a faulty ignition coil on that cylinder aswell.The P0420 is the scary one because it indicates a problem with Catalytic Converter system. Have you tried swapping the coils? If not do that first 👍
@@Singleturbocobra thank you for the advice. Turns out, after new spark plugs the blinking check engine stopped blinking and then went out altogether after a short test drive. No codes anymore so I'm tentatively hopeful it's resolved. Thanks again.
Yes it does .. I know this is probably really late but I just figure my problem out and I got a p0304 code and the check engine light does blink .. it’s because that code means it’s causing misfiring
Late or not I like the reply. Ty. I fixed mine by getting new spark plugs put in. Was going to do the full Injectors next but I didn't have to even tho I am still eating up a lot of full atm
@@ItsTheKris that’s great! I’m glad it worked out. mines unfortunately did not fix w new spark plugs so we’re going to test the ignition coils tomorrow by switching them out and see if it moves w it .. I’m praying it does bc anything else is Gona be a lot pricier and more difficult to fix .. to fix anything w the fuel I gotta take out my whole trunk carpet and my back seat since they decided to place it right in between the both.. it’s even worse bc I got a new (used) engine put in 2 weeks ago and already got to fix something
@Singleturbocobra Hey, thanks for replying. It's a two thousand eighteen toyota camry SE. 4 cylinder. I already swapped the coils. Remove the check engine light, drove it and the Check engine light came back on again for the same four cylinder misfire.
@@Singleturbocobra That's exactly what I'm looking at right now. Online. I will do that today. It's 4:26 PM. Where i'm at in california. I should know in about a couple hours just because I got stuff to do. Thanks for bringing it up. Hopefully I come back with some great news. I will keep you updated. Thank you so much anything helps

@@Singleturbocobra i like that
This was easy to understand, and professionally done. Thanks
Wuaaa gracias por ese tutorial me alludo en mi problema y yo mismo lo resolvi viendo tu video.
Thank you so much very straightforward no bullshit! ❤
Not sure why you put the cover back on when you have to take the coil back out
Well if he wasn't going to do it right then he was smart because if youndont don't right then but leave it off. You might lose it before you do the job or even lose a nut or anything.

^BS. Not necessary for a quick swap job. You do you.
To teach the people how to re install it. After the job is done?
@@jevonlemmermann4576I’m not saying it’s a big deal or anything but it’s literally two bolts, if you needed help with that then I’d say you don’t need to be watching a video like this anyway lol
Why did you put the engine cover back on after switching coils to test?
He doesn't need to put the engine cover back on
@@konstantin-bigexactly. Thats why he asked
Did you have to drive the car in order for the new code to come up?
Does this also cause a tick noise ? I have that code on a yuckon and passenger side makes a tiking noise
On a Yukon. In my experience the tick is a failing lifter.
I have a P0304 Misfire but I just recently got all my ignition coils, & spark plugs changed & tested however, my check engine light isn’t blinking.
I have the same code. Is it ok if I drive it for a day with this code
Great short video. Thanks for sharing.

Are there any other codes or is that the only one?
@Singleturbocobra yes, all fuel injectors codes and #1,#3 and #4 ignition coils and misfire on #4
@@sergioramos2413 That would lead me to believe you have a wiring or computer issue
@@Singleturbocobra so, it could be the ecm?
Thanks
Mine Lexus RX350is showing me p0304 cylinder 4 misfire detected. Does that also me that the coil is bad also?
@@urielnnadi9755 Did you switch the coil and recheck the code?
Thank you soon as my mechanic put my spark plugs in my engine light start blinking. Autozone had to tell me it was ignition coil4
Glad this video helped 👍
So the light won't reset automatically? You have to clear it out with the scan tool for it to go away?
Yes

@@Singleturbocobra an also now the car steering wheel lock when I'm not driving
Good but show us the rest how to troubleshoot shoot it completely like you said might be injectors or vaccum leak

You said your car was a Fiat?
What model?
What year?
Mine is not changing still get p0304 and have changed all spark plugs also !!!! What else it could be?
check your injectors for a leak good luck
Gracias por compartir tu conocimiento !!

And what happens if you switch the bad coil and put a new one. And keeps appearing the same code p0304?? Little help... you think i have to replace the fuel injector #4??
I would do a compression check next.If compression is good.Id definitely do a fuel injector
@@Singleturbocobra And if I did one and #4 is at 35psi. Now what? I got cam sensor and #4 after I changed it. Please help. Cali is killing me on smog

Aren't the coils 1342? Number order
That would be the order they fire in and not the cylinder location 👍
Thank you sooo much.
Cross my fingers hope this works or im gonna be f**ed 😢💰
I was just saying this cause I changed the spark plugs but the code still pops up on that cylinder😂
Con k m9delo de escaner cuentas
too bad my caravan has a coil pack, not indvidual coils.
I thought the firing order is 1,3,4,2. ?
That's right firing order is 1-3-4-2
