I had to drive home on a missfire and after replacing the spark plug and coil was hit with "catalyst system efficiency below threshold bank 1." I didn't know what to fix and started running down a bunch of clean catalyst rabbit holes. Finally found this video. I've ordered a new O2 sensor thanks to you!!
How did you get on?
Thank you for explaining. I just replaced o2 sensor but now i know what caused it to fail. Thank you Sir
Manufacturers program computers to cut off injectors to misfiring cylinders; as a result, you will experience a 25% drop in power. If the engine is a four-cylinder, your MPG will decrease by 10%. If that's alright with you, you can drive the car for as long as you want, assuming your country doesn't require emission tests. If it does, the only reason you need to fix it is to pass the inspection.
not all vehicles do that! I had 2 coils fail and i could smell raw gas!
Thanks for this detail explanation. Had me wondering to know why check eng light kept coming back after replacing both 02s... since not replacing the head gasket seals, yet
It been causing oil on the wires. Even though itvmay be 1 or 2 cylinder misfire only... 😮 need to get the gasket and seals replaced finnaly. Thanks bro
Great video. Also some manufacturers set computers to cut off injectors to the cylinder that is misfiring 👊🏻👍🏻
If the injector has missing signal, the computer cut off that injector. Then can I drive the car safely for some hundreds of miles until I get it repaired?
@@Knobber yes but it will be running rough
It has 6 cylinders, with 200HP. With 5 cylinder i still got 170. I just fear a little it can damage the catalytic converter. I've added some injector cleaner into the fuel to help out the remaining 5 injector. @@sheerwillsurvival2064
You’re the best. Thank you for all these tips.
Thank you brother I got a code of misfire on cylinder 3 i recently changed my spark plugs it cannot be the spark plugs time for new coil
It was the spark plugs actually that needed replacement lol i bought a coil for nothing
not for nothing bro now you know that you have a new coil if you need it better to be prepared than not be
@@yosoymichaelmyershow much was it to change the spark plugs
Straight to the point
Wow! Thanks
My moms car is a four cylinder and it had a P0304 and the check engine light was flashing. I actually seen a video talking about flashing check engine light referring to misfire and potential fuel getting into cat and damaging it. Idk if its true what another commenter said about manufacturers programming injection to cease in the event of misfire but me and my brother came to the conclusion to unhook that injector on that cylinder to keep fuel from reaching the cat and monitored how it was running on 3 cylinders. Didn't seem any worse so it was probably already only running on 3 cylinders. Hopefully the cylinder will be ok as long as its being oiled it should be regardless of combustion in that cylinder?
My 04 Sebring has a P0300 code (misfire on cylinders) and I took it to my mechanic and he said that the problem it is not the air , electrical, and fuel system but it could be the timing belt or worn lifters . What do you think it is ?
I ordered 8 fuel injectors and they delivered 1 😮. Amazon fixed the issue rt away though. I had a misfire on cylinder 4. Took the fuel injector out cleaned it up and codes went away. I don’t trust it which is why I’m replacing all 8. Fresh start. My question though. Is it true that can cause engine overheat? Needle goes up then bk down so idk what else might be going on.
What Catalytic converter?
I had all three of mine removed years ago.
I've been chasing a misfire code for about 2 weeks now
It started as a P0303, I switched cylinder 3 and 6 coils around and the code was the same. Later it changed to a P0300, I replaced all 6 spark plugs and got one new ignition coil for cylinder 3. The misfire was still there and the code was back to P0303. I've been driving around like this for awhile now just waiting for this car to blow up lol.
I'm still trying to figure out the problem, but at the same time I i dont care.😂
Were you able to resolve the issue? course I am facing similar problem currently

Funny thing is I found the problem. It turns out it was the injector wire on the connector, it was broken. I checked all six and what do know you all of them are dry and cracked. 😂
Low compression, 5 of my cylinders read 140 and 1 of them reads 135. Is that too much of a difference that would cause a misfire?
I have a misfire the codes are 300, 303 and 305…mechanic did an compression test and said cylinder 3 should have PSI of 90 and above but mine is at 25 and told me I need a new engine…is this the case or can this be fixed without replacing? I have a 2011 Acura Mdx
Informative
Do you think my car has gotten serious damage driving about 50km on a misfire
I have replaced, 4 coil packs, 4 plugs, 4 injectors, and I am still getting p0304 code. You can feel the slight missfire while idle but no loss of power while normally driving. Cam/Crank POS sensors were changed, no vaccume leaks, MAF cleaned. Wiggled the coil/ injector wires to see if possible issue and nothing.Did compression test and all cylinders are at 115-125psi dry and about just shy of 150 wet. Any ideas?
Same prob
@@392-oj-da-apeboys our transmission is gone 😔,gone continue driving till it goes out ig .Same problem
I’m wondering the same thing I have a misfire on cylinder 1, idle or low rpm’s are rough but smooth when up to speed or coasting.
@@FFARGONE yeeep same issue
I gotta Nissan doe ,wb yall
Hey man, love your explanations, vids. , T.Y. Q.Q. is it o.k. to mix manufactures when replacing cam,crank and coils ?
Yes it's fine
People with misfire you can’t fix check pcm mine just burned back somehow but still ran good would hesitate on light throttle heavy gas it was fine idk, plus my exhaust still leaks condensation driving for whole year
Fuel would also cause a fuel lock similar to a furor lock
So I had a 4th cylinder misfire... I didn't do anything for about a month using my car.
I initially changed all the spark plugs, but the problem still resided..
Then I changed one of the ignition coils. Problem went away.
But the problem I'm seeing now is that the car is running rich. My mileage reader is saying its knocking down 2 mpgs at a time sometimes, or more frequently.
If I put in new oxgen sensors, would the new one become contaminated??
How’d you fix your problem ?? I got the same problem right now
Did you fix it?
I have a cylinder 5 misfire that I am unable to resolve. It’s a GMC canyon. I replaced the coils, spark plugs, and fuel injectors.I am going to replace the fuel filter next but I am sort of fearing the worse case. I also replaced the valve cover and gasket prior to all these replacements. You think I need a new engine? I have 327,008 miles on it right now.
Were you able to resolve the issue? course I am facing similar problem currently
@@user-bo8cg9ur1l no unfortunately. The next thing that I would need to do is replace the cylinder head and gasket. I believe the valve springs and piston valves need replacing. The cylinder 5 misfire causes the inside of truck to smell like fuel which is really bad. Can’t run AC bc of it. Overall, truck runs like a champ.
I have a ford granada 1984 2.0 and it only runson 3 cylinders. How can I fix the car? I really don't watn to sell it.
I've done everything. I could to my trailblazer. We switched out the spark plugs. We switched out the coils we switched out. I am a gas thing. I don't know, but it's still only running on 5 and I can't figure out the problem. Maybe you can, is it the Cadillac converter right now? The engine light came on and my car shakes. It stays started, but I'm only running on 5. Can you tell me how to fix this? Or should I just take it into my mechanic? I have another mechanic and he's one that did the switching instead.All should be OK, it should be OK, but it's still running rough.Do you have any ideas?Thank you I don't have enough money to go to mechanic. That's why I chose this other guy who knows about cars and he got it running several times beautifully, but this time he can't seem to get what to do. He's done everything that the book tells him to do and still it doesn't. Change anything it still runs on 5 cylinders.
Not sure if you got this fixed since it’s been 2 months but changing the O2 sensors is worth a shot after you’ve replaced coils, spark plugs and valve cover gasket. I have the same issue, misfiring cylinder 2. Changed spark plugs, ignition coil and spark plug tube seals..no luck. I then plugged my computer in and got a threshold code for bank 1 and 2, or in other words O2 sensor. Replaced and fixed the rough idle and misfire.
@@Sohidden well I found out what was wrong the oil seal on the left hand side was bad so we changed it and everything's working right now, it was just an oil seal and it was leaking into my fifth spark plug put everything's going to be okay now thank you for getting back to me
Is it possible that the ECU can cause an engine knocking ?
Yes or no ?
Unlikely. You're most likly to experience stalling, no start, multiple engine codes etc... caused by a failing ecm
Got a question i just started my car (93 nissan 240sx) yesterday and it was having that missfire sluggish choppy idle even when driving it , would it be from my timing chain going out since its been rattling or my spark plugs that i havent replaced ?
if your timing chain is rattling, you better fix it. sooner or later it'll jump a tooth or 2 and smack your valves into the piston, and yes that'll cause a miss fire!
How can you fix an emission engine code P219D?
If the engine knows there's a misfire why won't it it turn off the fuel Inkector
My Madza 323f still misfire after changing spark plugs, coil
I have P0300 Code (Random misfire) 2013 challenger 6.4l how do I fix it!
Do you honestly expect an answer? Why not pay for a tech service or hire someone competent to diagnose and fix the issue. Geez!
My coil pack is more exoensive than my O2 sensors. 😂
Not a problem with my old '46 Ford Jailbar which had multiple dead cylinders. No computer, no fuel injectors, no catalytic converter. 18 years no problem.
My car is toast I need to sell it.
Same, idk if anyone will buy a broken car tho so idk what to do anymore 😅😭
Your holding something that most causes misfire, yet you talk too much about oxygen sensor that can be clean up and not talking about the thing that your holding ..
His topic focuses on ***consequences *** if NOT fix misfire, NOT the causes of misfire 😅😅😅😅😅😅😅
the Crack head take my caterpillar conversion thing 😢
Your comment just made the right side of my brain hve a misfire😂
That was suler c,ear
Are not that👀👀👀 cheap 😂
