P0300...How I fixed My code....P0300. Simple steps!

[@FixingWithPassion]

I hope I explained this PO300 trouble well enough for everyone. Bottom line my experience with code, seems to always be a broken/bad connection, bad sensors. ------Here is an Example and this one is a bit easier to figure out... .....(PO300 AND SAY A....PO304, tells you where to look) Cyl #4.

Nathan Rohrbough you did an awesome job! Currently trying to figure out the same issue on my ‘07 Camry

[@Nimatoofan]

Nathan Rohrbough now mine also threw a P0305 code so I know to look at cylinder 5. About 2 months ago I had changed all spark plugs and coil packs and the car ran great (check engine light never went off though). Now just recently the car started running pretty bad and idling hard and the check engine light started flashing (and that’s when I got a P0300 and P0305).

Great tutorial....!!! I have de same situation in my Neon... I did basically everything you did, which means, I wasn't so wrong, so next will be camshaft, and crankshaft or wires related, since I had also a P0499. Thanks so much for sharing your experience...!!!

[@andrewarmstrong7310]

The biggest cause of a P0300 is the battery. Every inspection should start with testing the battery, then go from there. To set a P0300 code it has to be something the computer directly controls, like the coils and injectors. It will not set a P0300 from carbon build up, sludge, worn or bent valves, worn rings or a hole in your piston.

[@FixingWithPassion]

Good point! Thanks for sharing!

I'm in the P0300 boat too. My wife drives a 2016 Nissan Rogue. It has very few miles on it - 4,400. All the sudden she took it out the other day and she said it was shaking. When I took it for a ride it was misfiring badly and I got codes P0301 P0300 P0219a. Since the P0301 is cylinder 1 misfire I first swapped the coils of 1 & 2 cylinders. Same P0301 and bad misfire. Then I swapped 1 & 2 plugs and the misfire code went to cylinder 2. Thought I solved it with a plug replacement but day later got rough idle and check engine light again but now P0303 P0300. So, I change all the plugs. Still rough idle and check engine light with P0300 code. Looking closer at the removed plugs they showed some carbon and fuel progressed up the threads - this was on all cylinders. Messing with my code scanner I found a monitoring function that shows how many detected misfires in each cylinder. Letting the car idle cylinders 1 & 2 show zero but cylinders 3 & 4 have progressively growing number of misfires. Just to do something I swapped the 1 & 3 coils and the 2 & 4 coils but no change. The car is running much better than when it had the first problem but still rough at idle and misfires sometimes at low loads. Seems better under load. Any suggestions on what to try next welcome. Thanks - Mike

[@billsmith2212]

I believe on the fuel pump there is a check valve . When you put your pressure gauge on to test , it should hold pressure after the key is off for a certain time period . If it drops too quickly , the check valve is bad . On a volume test , if your pressure gauge has a dump valve , with the car running , I believe about 16 ounces should come out in 30 seconds . That is a ballpark number . A clogged fuel filter or bad pump may slow it down .

I'm saying if you have a real loose timing chain or loose belt...it only takes 0.5 degrees for the cam and crank to detect a difference between the two of them. They may spin at the same timing marks, but the slack will noted in the sensors if slack or a different point of reference is seen in the cam and crank sensors. Even if one sensor starts to fail...it see's this as one of the two (crank or cam) are not in time, or thinks there not spinning the same time....then gives a code. In a nut shell.

Wow, can i just tell you that you know your shit!! The way you explained it was perfect. I've been dealing with a few weird issues in my 6mt 2003 350z. Once in a while i'll see a P0300 code stored but I would just clear it and it won't return for a few weeks, then back again. The moment you mentioned that the P0300 is misleading and is actually getting triggered by camshaft and crankshaft sensor values, it all made sense. My car is notorious for chewing through cam sensors and that one statement you made verified it in an instant. My other symptoms were slightly rough idle, and after a cold start with a minute or so warming up from a stop to crawling and driving if I hold the clutch a little too long at the bite point its starts jerking till it catches gear and gains speed. Never have this issue when fully warmed up driving throughout the day. Cam sensors work with oil, so temps matter which further proves my point that the culprit is cam sensors since the oil is cold and electrical signals are weaker, thus my jerking. Thanks a lot for giving info that would've taken me longer to find on the internet!

Nathan I need your opinion, I have a 2005 E36 6 cylinder Altima and it was getting P0300 so I caught a special on the spark plugs and coil packs and just went ahead and bought them. I changed the plugs and no difference other than a p0303 popped also so we know where to look. So I pulled the coil pack and closer inspection showed a hole burnt thru. So I changed all 6 coil packs as well. While I was in there I replaced the two sensors just to be thorough and it has been a while since anything other than oil change had been done. I cleared the codes and the car was running very good and no codes came back. The next day I start the car and starts hard, then test drive was very sluggish like starting in 2nd gear or something. Went back and checked and it had a new code pending whatever that means... an almost code I guess? P0171 bank one too lean. Quit for the day and came back the car won't start... turns over great but no fire. I went back to the sensor and noticed a problem with the sensor connector wire. Did not have one but pulled sensor, it was fine and put it back in then plugged in the connector and wire and tie wrapped it so it could not come loose. I ordered the connector and wire. Car starts right up and runs like a race car again. Get back from test drive and all is good, come back later and starts hard and runs sluggish again??? Like starting in second gear ? I cleared the codes and it is not posting any new codes, and one time it starts and runs great next time very sluggish? Several days later and still no codes but same issue?

The thing about the solenoid shorting out to the block was that it melted the crankshaft position sensor in the block ,which was next to the starter, so I thought it was the sensor causing my problem.

[@300zxdriver]

Most of the steps you did were not related to a PO300. If it was a plug ,coil, wire, or compression you would have a fault for the number cylinder ie PO 302 etc. You need to look for something common to all cylinders. Also most of the time the PO300 code the engine runs fine sometimes. If you had a bad fuel pump and or fuel filter it wouldn’t run good period. So what’s left? Cam position sensor and crankshaft position sensor effect all cylinders.

[@FixingWithPassion]

True, but if there is a issue with s plug, wire, or compression its good to resolve that first. If there is actually a miss, bad coil, low compression its not going to help anything. Just verify that stuff, Then move on to electrical codes etc like you said. Never stop learning! Thanks for watching!

No compression check cause I no th block is fine do to it running perfect on and off. ......long block 4.3 litter v6 vortec intake. But ya everytime it starts to misfire...witch is at ...always stop signs and starting out all of a sudden it stops that little tick noise then runs like its normal self then like a switch stops running good loose hores power and the whole thing shakes them again is fine. It's obviously what is making the ticking noise but I can't figure it out . So I guess fuel injector on 4 but not sure. Basically before I get into this I live in this van for the next 3 months so hard to work on. Is it a known thing that fuel injectors make that tick tick noise louder if they at bad ? Or do you think I have something else. ?

Ticking lifters are not a bad thing just annoying to here. Probably no whats causing the miss fire. I start looking at the fuel pressure first. See if it looses any fuel pressure when you shut it off. My neon gave me a po300 and found out it was a loss of fuel pressure.

[@bigOsharp]

If not a blue spark 💙 need a coil yellow bad 💛

[@ceezauto213]

@Nathan Rohrbough Hi thanks for the video I have this p0300 code in my 99 Infiniti i30 and my spark plugs have oil in the threads. I changed the spark plugs and fuel filter and still have the code. Also I hear a hissing sound around my throttle body. How can I locate this hissing sound and will it have anything to do with oil being on my spark plug threads? Thank you

[@sublimegabe]

Old but just in case you haven't solved it. You need to replace either your valve cover gasket or sometimes a small gasket that's just for the spark plug tubes. The oil is bypassing the gasket entering your spark plug tubes and that could be causing your misfires.

@@sublimegabe Fixed it already. It was 2 bad fuel injectors. Thanks tho

[@sublimegabe]

Thanks friend good video

I have 2017 Kia Sportage I changed all wires and plugs still misfire 1 &2 what else should I do

[@ZeJama]

Check air leak and ignition coil pack most of the time ignition coil pack are going bad

[@RobS282]

lol you dont want the engine to take off when the plugs are out ????? how does that work ?

[@JuliusWballoverflag]

Mine was the ignition coils and spark plugs

[@asiroproductions]

Mine tho

Did you place your mic down into a deep cup of water to try and record your audio?

[@yardkidd87]

Good video

[@Warrior_6416]

Great video! On a side note, what did you use to record the video?

[@BigJuanG]

What if I just got my spark plugs changed

[@Anthony-tg9vs]

10-4 thank you

[@JasonSmith-qx3zh]

I thought it was a good thing to check the gap on the plugs make sure they are gapped right!

[@FixingWithPassion]

yea

[@gregjack8632]

Great video sir ! 👍

[@90struckscene75]

Hello this is the 3rd time I’ve gotten p0300 code on my 1999 5.7 Tahoe. I noticed it sometimes starts a bit sluggish. I replaced spark plugs and wires along with coil and ignition module but hasn’t fixed the problem. The code appears when driving at 40 mph. Any leads on what it could be?

[@jeronimocarrizo9962]

I HAVE THE SAME PROBLEM. AND IN MY CASE WAS THE CKP SENSOR THAT HAVE A SHORT

[@davidortiz4903]

Wow great video🏆🏆

[@FixingWithPassion]

wow!

[@roadstar499]

I watched a video that was a year old finding po 300 the guy used a TopDon obdcan plus scan tool...it showed which cycl was misfiring and how many times..i think it even did live data...they are under $50...i think scanners for the dyi guys are getting better all the time and less expensive... currently i use a cheap app that gives codes...

[@FixingWithPassion]

Good to know! Thanks!

[@azolivas]

Well I changed my spark plugs but still no luck but now I’m getting a new error about Traction and Stablink not working now. Ugh. I’m biting the bullet and having it towed to a shop.

[@joseloterry]

I Start to use chevron gas 93 and fix my problem

[@Pooponthecouchh]

I have a p0300 now, I’ve replaced coilpack, spark plugs, plug wires, and new injectors (e85 ate through the injector) could fuel pressure be my problem?

[@aaron5785]

I would check your fuel pressure at your fuel rail with a fuel pressure gauge. Could be a weak fuel pump or faulty fuel pressure regulator.

[@daverees8644]

I removed my egr valve and cleaned it although it was relativley clean, i changed my cam shaft senser but still no change so im gonna replace my coil next, the p0300 code is a pain on the ass.

[@FixingWithPassion]

Check your fuel pressure. I had the same Issue. It should not be loosing any fuel pressure when the motor is not running.

[@drew2truth]

@@FixingWithPassion if it loses fuel pressure after shutoff it is most likely a bad check valve in your fuel pump(hopefully this, it doesn't need immediate fixing as its just a startup commodity) or a leaky injector which must be replaced immediately or you will have a visible leak in a line somewhere maybe a o ring whr lines go into injection.

[@mike856ms]

Hello Nathan. I have a 2003 Oldsmobile bravada. I have 2 codes P0300 and P0113 Which is intake air temp sensor. Would a bad intake air temp sensor cause a P0300 random? Thank you

[@carlosmejia5728]

🤔Think this way :The intake air is for THE ENTIRE ENGINE=ALL CYLINDERS ...so of course it can trigger a P0300 code..😜

[@mike856ms]

@@carlosmejia5728 thank you for responding. It turned out one of the connector wires was cracked. So I replaced the sensor and it cleared the code. NOW I still have P0300. After replacing all coil packs and checking the fuel delivery I'm stumped. It runs rough. Any suggestions? Thank you

[@strategicservices9906]

p0300 only w/ cold engine- miss. when warm runs great. What could it be?

[@FixingWithPassion]

Borescope the cylinders for a leaky head gasket.

Where is EGR located on porsh cayenne v8 2008 model

[@FixingWithPassion]

[@soondarlalkemraj9742]

Code po300 your have to look for a vacuum leaks first that is what i did and was the throttle body gasket

[@Bruce-mh8mo]

what if i get a P0300, and a P0301, P0302, P0303, P0304 but my engine runs fine? is that just a vacuum leak in the intake somehow? almost like a bad/dirty FITV?

[@FixingWithPassion]

Add them all up and you got a sinking ship!

[@bryanviveros]

Has anyone ever worked on a 9 cyl engine but doesn't have a cylinder one? Asking for a friend skip ahead @2:47

[@themostsecretscience6409]

I saw that too.

[@duanedonaldson2262]

I do not keep cranking until I get max compression, I look at the first good compression stroke and the 5th stroke and compare all cylinders. a weak cylinder can build up to max after enough cranks, not a good procedure. A running engine will act differently. When I say first good, you may already be on a compression stroke and get half a pump so do it again. Also be aware of a weak battery and as you work your way around the cylinders they may be lower and lower based on weak battery. So of course I need to be able to see my compression gauge while I am cranking from the key to see the first and fifth strokes. DONT TRUST scanner codes, it is only a guide, prove out your problem by testing. The older the car, the less smart the computer is, its simply a fact of life.

[@carlosmejia5728]

You chose an extremely easy car for your demonstration, everything is handy !

I get lucky sometimes.
