P0300 Explained - Random/Multiple Cylinder Misfire Detected (Simple Fix)
Vložit
- čas přidán 6. 07. 2024
- The FIXD wireless OBD2 scanner and free app for iPhone and Android translates your check engine light into plain English so you can rest easy. In this video, we explain what OBD2 code P0300 means and possible causes.
P0300 means one or multiple random cylinders misfiring in your engine.
A misfire occurs when an insufficient amount of fuel is burned in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine. A misfire from two or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure.
When P0300 occurs, it should be fixed immediately as long term driving with engine misfires could cause consequential damage to your engine and catalytic converter(s). Many times, P0300 occurs when there are worn out spark plugs, spark plug wires, or a faulty ignition coil.

“Don’t ever trust a mechanic “ words of wisdom right there! Same with lawyers, real estate agents and doctors 😆😆😆
Only trust in the Lord, for all men are liars
Lol *brings car to a mechanic when he doesn’t know what to do*
Doctors?
My rule of thumb is to never trust anyone who knows more about something than I do and can charge me money for it.
I love this video and saved me a tow and dealer repair charges. My 04 Golf all of a sudden gave P301,302,303 and 300. Could not drive the car and ran ultra rough. I swapped out the battery first and that fixed problem with no more error code and motor runs perfect as it always does. Thanks again for the video and saving me lots of money.
Yeah there is literally no way a bad battery would cause a car to run rough. What do you think a battery does exactly? You probably had bad gas but had already burned most or all of it before changing the battery. When you disconnected the old battery you reset the ECU and all DTCs with it. See what happened here? Since you cleared the codes yourself they weren’t there anymore and since you probably burned off the shit gas the codes weren’t about to come back.
Congrats, you spent $200 on an issue that would’ve sorted itself out with time and a $7 bottle of Lucas fuel treatment.
Yeah a battery wouldn’t cause that issue , I bet fowled spark plugs , bad wires and or ignition coils are shot . I have a mk4 golf gti vr6 .
I had P0300 error code on my Jeep Patriot and took it to my regular repair shop. It did not seem to have any abnormality. The shop manager ran a computer diagnostic and it turned out there is nothing wrong with it. He said sometimes one random misfire on any plug for no reason will cause the computer to remember and display this code. He reset the computer and charged me $0. He told me to come back if I get P0300 again. Just wanted to share my experience here and great job explaining the potential problems.
Did it happen again?

Glad to hear it! Thanks for watching!
Fixed a f150 with a P0300 and multiple misfire codes for all cylinders. 96 straight 6 low data rate misfire monitor and a stick transmission. It was the Ujoints. They were binding and slowing and speeding up the engine causing the misfire codes.
I kept getting the P135B code on my 17 Traverse. I had a hunch it was spark plug related. Shop couldn’t find anything wrong or misfires. Today it started throwing P0300 codes. Putting new spark plugs in now. Will update later . Thx!!!!
Results?
Changed ignition and spark plugs but don't seem to work, what could be done next?
Or you can always try putting the antenna up and tune your radio to 107.7 at midnight to receive the reset misfire signal and you should be fine
Perfect video tenks
So, is it the P0300 that caused the P0014 code on my 2014 Nissan Rogue, or other way around? I’ve read so many different opinions and fixes here on CZcams that I don’t know what to believe anymore. Some videos talk about replacing camshaft, VVT sensors. Vehicle has 101,000 Kms, so I guess I can start with a new set of Iridium spark plugs, even though original ones are supposed to go to 160,000 Kms.
Thanks.
Great video
Love this video it explains everything u my new teacher
I changed every component on my jeep that would cause a misfire and I'm getting a cylinder 2 and a P0300. Not sure whats going on with it. its a 2008 Jeep Wrangler Unlimited

Nice my friend blessings
Will I pass the state (California) Smog test with this code? if there is nothing else wrong and no Check engine light?
Great explanation.
Very good!!
Thank you, Alberto!
I got this code on my mustang 5.0. Everytime the check engine light blinks the car stalls n u can hear it n when I try to hit the gas it goes nowhere.
i got this code on 98 tacoma, after reading some comments if a battery had to do something with it, I was skeptical too, and after watching an Scotty video he mention that a bad battery can affect the computer and send all kinds of codes , in my case i cleaned the terminal connectors , and after 300 miles no codes so far

Hey, i have a grand Cherokee laredo 2009 3.7L , there was a problem with coil number 5, i'v replaced it also replaced spark plugs, but some times when i'm driving the car suddenly i feel a high vibration it looks like from the engine but when i stop the car and start it again after 1 minute i don't feel any vibration, with a scanner there is misfire with cylinder 3, any thoughts about the problem please!!
Misfires can be caused by several different things. It sounds like you're on the right path with replacing the coilpack and plugs. Always be sure to replace the spark plugs with a good quality plug. Example is an O.E recommended replacement, and be sure to replace all spark plugs at the same time. P0300 is a fault for random multiple misfire, P0303 is misfire cylinder 3. If cylinder 3 now has a misfire you can quickly find out if this is a coilpack issue by swapping the coil pack from the cylinder with the misfire code to a cylinder that does not have the fault. Example for cylinder 3 misfire. Engine off Locate cylinder 3 coil pack. Standing in front of the engine , driver side (bank 2) there will be three coilpacks. Counting from the front of the car to the back these cylinders are 1,3,5. Remove the coil pack from cylinder 3 and swap that one with cylinder 1 or 5 (all coil packs are the same so whichever one is easiest to get to). Reinstall and start up engine. If the misfire fault moved from cylinder 3 to the cylinder you installed the coil pack, you know that you are looking at faulty coil pack.Now there are a few other things that can cause a misfire. Look for any vacuum leaks. There are many plastic / rubber hoses under the hood and over time these can become brittle and crack or break. When this happens unmetered air can be entering the system causing the vehicle to run lean and causing a rough running issue or misfire. A vacuum leak can be hard to find and may require a smoke test to be performed in order to find the leak. There are a few different ways to quickly check for a vacuum leak. First do a visual inspection looking for any cracked lines, hoses etc. Then gently move the hoses, lines etc around and listen for any hissing noises or changes in idle when doing so. Another way is to spray a small amount of brake cleaner or carb cleaner on connection areas. This will increase the idle also letting you know there is a leak. BE SURE TO NOT SPRAY CARB CLEANER OR BRAKE CLEANER ON HOT SURFACES OR IGNITION ITEMS AS IT IS FLAMABLE! A few other things that can cause random multiples engine misfire are faulty fuel injector, dirty fuel injectors, dirty or clogged fuel filter, vacuum leaks, mass air flow sensor along with other sensors in the system. Once all other items are ruled out next step would be to check engine health by doing a compression / leak down test. This may be something you will need to have your local auto shop do as special tools are required.
Hope this helps!
Only problem is most cars now a days the voltage regulator is computer controlled like with Honda and the ELD in the underhood fuse box, it reports to the ECU to tell it what to do as for charging the field of the Alternator to put less load on the engine. Turning on thing's like headlights and blower motors should make the ELD tell the ECU to crank up voltage from the Alternator and if it doesn't you could get the wrong reading
You guys are like donut. I dig it.

I have a 2000 JEEP Grand Cherokee with the 4.0L Straight 6 and when starting it up sometimes it will have a really nasty misfire and if I just rev it up or just start driving you can hear when the other cylinders actually start firing. I have codes P0138,P0300 has anyone else had the same issue as well??? I've changed plugs and didn't really help then I bought the coil pack and yes its the weird one where you get all 6 on a long bar. When I replaced that my JEEP would not run at all. So I put the old one back on and it ran fine other than the misfire once in a while. Its not every time I start it just when it wants to be stubborn. Any ideas anybody??
Check the compression first. Then look t the fuel injectors. Could also be bad ignition timing due to a worn timing chain.
I can not find how to check my battery in the app

Even a bad transmission filter can make your vehicle run ruff, or say a bad catalytic converter.
Can anyone tell me if misfiring cylinders can cause an engine to seize? I have a 4 cylinder honda; the engine seized a couple of days after I had the scan done.
@Andrew Dean Thank you. I thought the guy who sold me the car was just unloading a problem on to me; turns out I got a hole in the oil pan somehow....
Por favor, xq no hacen videos en español así nos ayudaría a los que no dominamos el inglés..gracias
I had this code on my 2001 MK4 Golf gti vr6 , found out that i was running the wrong type of NGK spark plugs , I needed to run NGKR instead , the only thing was that my P0300 showed up as a ghost code on my OBD2 scanner .
2:10 in the video, the issue with a vacuum leak is going to be a lean condition which means insufficient fuel, too much oxygen for the mixture as another way of saying it. I would recommend a correction to the video.
You are absolutely right! The guy is this video said it wrong! A vacuum leak would cause excess oxygen as it would be sucking in more air thus throwing off the air fuel mixture and causing a lean condition!
Help please! So my 370z has CEL on with random misfire code P0300 with high idle of 1000 RPM at cold start. I've changed sparkplugs, welded a crack in the catalyst converter, cleaned air intake filters and CEL didn't go away. What's your advice for the next steps? Should I change coil pack, fuel filter, and camshaft position sensors? Thanks
@@brandontran5160 If the idle will not return to 'normal' with some runtime, also with a multi cylinder misfire code, I would expect you have a vacuum leak somewhere. That would be the first thing to rule out anyway if there are no other codes. The crack in the cat also suggests maybe (not always) but that it could have experienced excessive heat which is another symptom of a vacuum leak, if the mixture is lean it will increase the exhaust gas temp. This can be hard on an engine if it is a large enough leak to keep the condition lean during heavy loads.
There isn't a lot of information in this post to draw any more conclusions, but I would start it and let it idle, listen around the engine bay for sucking sounds, review the vacuum lines for integrity and make sure all are attached where needed. Sometimes during service a line can be left off and it is a simple as reattaching.
Google the year of your car, model and 'vacuum diagram', it's likely you will find a diagram with the lines to check.
@@moparmadness74dodge So I replaced the camshaft sensors. Now my 370z is sluggish and can't go pass 2200 rpm. I checked again and it still give me code P0300 plus new code P0011 and bank 1. I reset CEL and it works sometimes and I could drive pass 2200 rpm but the CEL keeps flashing while driving. Does that mean I need to change ignition coil on bank 1? Thanks
@@brandontran5160 p0011 indicates that the cam timing is more advanced than what the ECM has commanded.
Not following the idea of an ignition coil being an issue, perhaps you have an issue with a cam phaser.
I’m not that familiar with a 370z or the issues that they commonly experience. Some out there saying it could be the cam phase sensor itself.
Can it be o2 sensor fault??
How can I get FIXD for detector For transmission
I’ve been a mechanic for 30 years and never had a battery cause a misfire…especially since the batteries only job is to crank and start the car. Once the car is running the alternator takes over charging your battery and maintaining Voltage to your computer systems… a battery causing a misfire? Sorry can’t agree with that one.
Man I've been a mechanic for 40 years and never heard of a battery causing a misfire I just had to comment on this video thanks for saying something before I did though I can't believe he pinned the comment thanks I changed my battery and it helped me fix my car no way in hell the battery calls the misfire..

My car was shaking and throwing alot of fumes through the exhaust. when i got home it didnt want to turn on until i stepped on the gas and turned it on. not it turns on but burns through fuel quickly and i got the code p0300 can you help me figure out the problem
Check your spark plugs first, probably replace them either way given how cheap and easy they are. If that doesnt help, test or replace the ignition coils with a spark tester or multimeter google it, if the coils are good next check/replace your fuel filter, if that's still not fixing it, try a fuel injector cleaner, after that look for leaks in your vacuum lines and intake system, last thing it would probably be if its not any of that its time to replace the fuel injectors.

Me gustaría oírlo en español gracias
Decent explanation but $60/40 labour to change each spark plug? That's insane. It should take less than half an hour on the majority of cars to change ALL plugs.
Do it yourself then?
That caught my eye/ear too. He shouldnt list "per plug" but he is about right on the costs and even under in some cases. All three of the vehicles we have require the removal of the intake manifold to access all the plugs. Just about any modern V6 or smaller is going to be like that. It took me the better part of two hours to do them on a 2013 Town & Country...and you know book rate will be at least double that. At just $90 an hour you're looking at probably at least 3.5 hours on book rate and if you figure 6 plug you are at $52.5 per so yeah, that's probably about right.
On a 4 cylinder yes, but on a v6 it’s a pain in butt sometimes. My Chevy s10, 4.3 has a spark plug right behind the drive shaft. It took all day to get the wires and plugs out
😅 yeah, BUT on this one you actually bbw l need to pull the engine forward in order to be able to reach back there.
I got an xterra, and I had to dig to get to my spark plugs. Mechanic said it would be $600, I spent $100 and a weekend instead lol😂
See at least one problem, the battery main use is to start the vehicle once vehicle is running the alternator does the power to electrical system not the battery hence cranking amps the ability to crank over the engine
Bro them prices are insane. You getting your work done in a Bentley in Beverly Hills? Lol. It literally took me 15mins to change all 4 of my injectors. $40-60 each if u get from auto dealer. Maybe 150 if you have a serious sport car.

Doesn’t the alternator take over after the battery starts the car?
It takes over most of the load but Not completely, like your radio will shut off, guages, and other electronics , so yes the alternator can run a car without a battery but it doesnt run everything. You wont go far.
If the battery is bad it will suck more power than the alternator makes and kill it. Especially if you have lights and radio on
Let keep throwing parts at it, until you run out of parts.
If you are going to throw parts at it like the video suggest. Take it to a mechanic IT WILL BE CHEAPER.
