Mystery Misfire? STOP WASTING YOUR MONEY

This Video im helping a lady find out why her 2005 frontier is running rough. So im showing how to properly diagnose what is causing the misfire before spending a dime
**FLASHING CHECK ENGINE LIGHT, whenever thats flashing instead of steady, thats your computer letting you know that its seeing an event that can potentially harm the catalytic converter. yup! eventually a simple misfire can turn into a very expensive fix if not fixed quick enough**

I had an intermittent misfire on my '98 LeSabre 3800 engine under acceleration. No codes. Idled fine, ran down the road fine. Decided to look at the plugs. #4 plug had a crack along the porcelain portion of the plug causing occasional missfires. Didn't find the problem until I physically removed and inspected the plugs. So yes, it could be a plug problem.

I love intelligent people ! so many shops just love to replace parts due to lack of proper training .good job you made my morning coffee taste better ..ha !!

Perfect explanation, thank you.

[@LIFEJOURNALTV2021]

great video, very well explained and nice tip. Thanks. Keep up making videos like this.

[@mattwensel7676]

"simply" switch a fuel injector- someone hasn't worked on many direct injection engines

[@chrisdavidson3180]

Love it! Thank you..

Great keep up the good work !

@@NoNeedGaragewhat if after moving the injector. It doesn’t change? And even after performing compression test ..all cylinder found to be okay….what is next?

[@NoNeedGarage]

@@efivegauthierchryslercanad3066 So a compression test is a bit of a broad test and doesn’t always show a smaller compression leak, a proper leak down test would be better suited We can chat further if you would like, Please email : [e-mail]

[@NoNeedGarage]

@@efivegauthierchryslercanad3066 also another possibility could be the wiring to the specific cylinder, for either the injector or coil, or a possibility even an injector driver in the ecu depending on the car You would need to verify if the plug is actually creating spark, and if the injector is getting a proper pulse signal from the ecu (via a noid light) But as mentioned, email [e-mail] and we can chat further in detail about your issue

[@MUHAMMADKHAN-pe7ez]

sir, you ignored the ''first thing first'' rule. your video should have been covering the ''air-fuel issue'' first/ anyway, everybody is his own boss

Really good video.

So previously the car blew the head gasket and the coolant was escaping into cylinder 2 but that's fixed but I also had a red hot catalytic converter, could this be fuel related

[@ismaelmelendez7808]

2020 Jeep wrangler 54,000 Multiple Missfire took it in to the dealer blamed. Me for slush in engine so I took it home and changed spark plugs and coil and still acting up jeep told me I need a New engine now it sits in my Driveway I change the oil every 3,000 miles but since I never used there services they gave me the Finger

[@BLACKWOLF-1911]

My V.W. shows misfires on 2 and 4. Bought new plugs and coils cleared codes, came back 2 and 4. Changed coils to Bosch o.e.m. cleared codes, still 2 and 4. Compression test good, plugs and coils look good. I'm out of ideas.

[@Farhad_ZKD]

You need to check the Injectors. They might have got clogged. Just put a bottle of Injector cleaner in a full tank and drive the car or let the engine run idle

[@Dont_stay_long_k077]

I've just been told to scrap my 2014 vauxhall Agila, 62k miles , had reg services , cylinder 2 missfire , they told me plugs and new coil pack still ain't cured it and they've gone on to say the engine needs stripping etc etc , I'm devvoed

[@alext8828]

Did they do a leakdown test to determine what the problem is?

[@SuperBC10]

Is it still running ok apart from that misfire? Vauxhalls are well known for this misfire. A lot of the times it’s the damn EGR valve especially since this crap E10 fuel. I’ve changed 3 on my Zafira since this stuff has been forced on us. Try giving it a clean or get another one. They’re simple to swap over, 2 bolts but they are a Torx head so be careful they’re not rusted up. For the sake of £20 it’s worth a try. Otherwise run it until it dies. Or then get a new engine. It’ll last much longer than any off these newer cheap, not built to last engines these days. Good luck.

[@vince2113]

Hey, I got a P0300 code on my 2009 Infiniti G37. my mechanic told me to install new spark plugs and which did (NGK iridium the best I could buy). AFter a week same P0300 code came back. Would i need to change all coils? because my code does not pin point like this video which cylinder is misfiring. Any help would be appreciated.

[@amkande9230]

Hey Vince Have 02 Q45. Can you update me how you fixed your problem since I am experiencing the same issues. Thanks in advance!

[@BuckingHorse-Bull]

misfire but throwing no codes on my 2013 hemi 5.7 it started after i put some oreily brands fuel injector cleaner. matter of fact the drive after using the oreilys fuel injector threw a flashing check engine light while driving. and the misfires are random

[@NoNeedGarage]

Sometimes the codes take a little time to pop up, But I’m personally not a fan of adding those shelf fuel treatments, If I want to service my injector, then I personally take them out and take them to a place who can clean/ flow test them to ensure they are matched and have a proper spray pattern

[@buckweezy1942]

Im getting a p0300 on a 2018 jeep Cherokee.... swapped da plugs and 02 upstream and still getting code?

[@NoNeedGarage]

So a p0300 is a random misfire Which is typically caused by something that affects all the cylinders, are there any other codes accompanying the p0300?

[@buckweezy1942]

@@NoNeedGarage I had a p0171 but I replaced the 02 sensor in bank 1 and it went away, still getting da p0300
