SIRxMARCUS why did blown oil seal cause misfire? I've some oil found around two spark plugs and I have hesitation and inability to accelerate beyond 4000rpm. Can't go any faster than 120kmh
In my car, i had a valve cover oil seal fail around 100000 km. Somehow i eventually decided to bring it to the mechanic and have the valve cover opened, what was inside cleaned up and the seal replaced since it also had noisy lifters and once the engine went warm most oil started leaking and getting onto the converter making things smelly. Well, the mechanic also had to remove the coilpack in the process and found that oil was starting to get around the connectors and sparkplugs (coil-on-plug design) and cleaned everything up. The engine could have started misfiring any moment once enough oil built up inside that area. And the lifters became quiet again too. All of this costed 80 bucks, a new converter and coil pack could have been a lot more expensive than that.
Experiencing the same issue too. Engine runs fine until you get to higher rpms, then it throws a check engine misfire. Compression is good, fuel injectors good, spark plugs and gaps good, coil packs good. Mass air flow sensor is good (although these are known to fail without throwing codes. Haven't checked fuel pressure or catalytic converter yet. My bet is a bad catalytic converter, just by smelling the fuel enriched exhaust.
@@danielsotelo44 The problem for me was a bad intake camshaft due to incorrect specs for the valve clearances from the factory manual. The camshaft grinded all my high cam lobes and broke 2 rocker shafts causing the misfires in the affected cylinders.
@@cartels. Catalytic converter cut. Turned out to be a wiped intake cam again. Ordered new intake rockers and intake cam and all is good for now, power is restored.
@slotskingsget a code reader that can record live data and record the issue happening multiple times go thru the data and try to make a diagnosis like that. Don’t just start replacing shit, the commenter above shouldn’t be giving advice the difference between a parts replacer and a mechanic is the ability to properly diagnose a problem. Changing everything related to the problem until something works is a horrible way to diagnose 😂
My car did that once unless I kept it above 3k. Under load and under 3k RPM, the number seven cylinder would misfire and the whole car would shake pretty badly. Had a bad coil.
Ignition coil Fuel injected engines have these things called coilpacks. The computer talks to them and tells them when to fire instead of a mechanical distributor. Much more reliable and much more efficient system, but more annoying to work on. They call them coil packs because instead of a wire going down to the spark plug, it's a long spring, or coil if you will
Every heard of a go pro camera? They attach to anything. Clip to your shirt, clip it to your hat bill, anything 😉. Lot of TH-camrs use go pros to record with.
I have an 03 Acura rsx. Once I hit 4K rpm is starts idling and jerking. I have to drive the car for like 20 min before it starts doing it. I’ll be at 4 rpm on 5th gear , drop it and the car just doesn’t go it just loses speed
I'm currently having the same problem with mine. Gonna sell the whole car and someone might want it. Has some new parts in it from previous recent repairs. Currently it honestly scares the shit out of me driving it because it randomly stops for a second then goes again, and it feels like the car is about to throw me out of the car through the glass.
I must have been lucky. 191,xxx miles on my rotary engine with zero issues. But used mixed fuel and always kept it in high rpms while driving warmed up. But I had a 12a engine.
Does your car buck and jerk when it misfires? I have the same problem but it happens at low speeds also and it doesnt matter what the rpms are when it does it
Auto Care Advice: Misfires and Their CausesIgnition Misfire An ignition system problem is one of the most common reasons for an engine to misfire. As the spark plugs, ignition cables, distributor cap and rotor, and ignition coil wear over time, their ability to transfer the needed spark to ignite the air/fuel mixture inside the combustion chambers becomes compromised. In the early stages, the spark will only be weaker and the actual misfire will be subtle. As the ignition components continue to wear, the misfire will intensify and the combustion process can be interrupted completely. This will cause a severe jerk or shock in the operation of the engine (the engine may even backfire through the air intake system, producing a loud "pop").Lean Misfire The lean misfire is another common reason for an engine "miss"-this is due to an imbalanced air/fuel ratio (too much air/too little fuel). Since an engine needs a richer (more fuel) mixture for a smooth idle, this problem may be more noticeable when the vehicle is idling. The lean misfire may decrease or disappear as the engine speed increases because the efficiency of the volumetric flow into the combustion chambers increases dramatically. This is one reason why a vehicle gets better mileage on the freeway than in the city. An EGR valve that is stuck open, a leaking Intake Manifold Gasket, a defective Mass Air Flow Sensor, a weak or failing fuel pump, or a plugged fuel filter are some of the many causes for a lean misfire.Mechanical Misfire Mechanical problems can also cause an engine to misfire. Common causes of a mechanical misfire are worn piston rings, valves, cylinder walls, or lobes on a camshaft; a leaking head gasket or intake manifold gasket; damaged or broken rocker arms; defective fuel injectors (and/or the electronics that control them); and a slipped or incorrectly-installed timing belt or timing chain. Generally, this type of misfire has more of a "thumping" feel to it. It is usually noticeable regardless of engine speed; in fact, it may even intensify as the engine speed increases.Powertrain Misfire Sometimes, the engine has nothing to do with a misfire. One common cause for "jerky" performance that feels like a misfire is a problem in the transmission and its ability to properly up- or down-shift. If the misfire occurs during higher speeds, it could be a problem with the operation of the overdrive gear or a chattering clutch in the Lockup Torque Converter. If the vehicle jerks or feels like it is "missing" during deceleration, it could be due to harsh transmission downshifts, badly warped rotors, out of round brake drums, and/or sticking brake pads or brake shoes.Make sure that you have the vehicle properly inspected in order to determine the root cause of the misfire. Entire engines have been replaced to solve a wrongly perceived mechanical misfire problem that was actually rooted in the transfer case, transmission, driveshaft, or front/rear differential.
Way safer than the dumb whores scrolling through Facebook at 30mph or in traffic. Less annoying too, he’s probably not even looking at the camera too much.
I had the same issue in my 2013 Genesis Coupe. The check engine code told me there was a misfire in cylinder 1. The issue got so bad that the car literally could not go over 70 mph. A month later a head gasket blows and my engine block cracked. Now I have a totaled car :)
Mazda Rx8. Redlines at 9k. Cuts spark and fuel at around 9.5k ish. And they are balanced to run up to 11k, which some people tune for. But there's little to no power there without a turbo.
You can fix this for free. Hold the odometer reset for your trip meter and turn key on but don’t start engine. You should see the word “test”. Turn off and repeat. Next, turn car to on position and pump brakes really fast until the oil needle spikes. This resets your eccentric shaft position sensor and your car should stop misfiring.
I'm having this problem on my 5.7 hemi I've already changed the spark plugs and coil pack on the misfiring cylinder and pen pointed the issue to being the lifters and maybe the cam
Shit really? My ram has been doing the same thing and I changed the same parts on cylinder 7 along with a new injector and still doing it. Driving me nuts trying to figure it out
Simillar thing hapened to me. I was very lucky that the problem was just a faulty ignition coil and I self diagnosed it. Just get a Toyota and you won't have difficult problems xD
I have got it on Opel vectra c above 3000-4000 rpm it misfired, shaky motor and engine light goes on. I have changed coil pack, bougies it didnt work, please help.
spirit Rx7 Well if you "LOOK" carefully on the steering wheel you'll see the "MAZDA" emblem on it. So that's how "I know". Which is not really knowing it's called being observant. The tachometer doesn't tell me much because I DON'T know the model. If i observe that it was a mazda doesnt automatically mean ill know what the vehicle is. And thanks for the answer though.
I have had 3 rotaries, 2 at the same time for about a year. Every one of them drove me nuts and there was always a different issue. Damn things never ran right.
Marcos Mendez you are right there is a trailing and leading for each rotor only thing is if you have more rotors such as the 20b engine which has 3 rotors 6 spark plugs you won’t always have 4 plugs. There is even a 4 rotor called the 26b and it has 8 plugs
My shit hits 4,000-5,000 rpm when going 30 miles per hour. not every time. Not sure if thats a missfire. the only way to stop the loud noise it makes is by coming to a complete stop. also if i let go of the gas when it makes this loud as noise it stars slowing doing so fast as if i were slightly hitting the breaks... very dangerous because it slows down really fast and im not hitting the breaks so the person behind me doesn't know that im slowing down fast, to remedy this i have to leave my foot at the gasspedal so it will continue at a steady miles per hour. This happens even at 30mph actually very offten if i acceleatere too quickly. so im crusing down the street at 5,000rpm at 30mph XD!
same here, i think its the fuel pump going all bad. When i press the accelerator in first gear the car isnt showing any significant change in how fast does he go. Its bad at idle af too. But if I change in fourth gear i feel like its better but its still shaking.
This is not a piston misfire but a lost in compression I think, rotary engines loose compression overtime when apex seals start to wear out, I don't know whether rotors misfire, this is only true if this car has a rotary engine, which I think it does because it sounds like a rotary engine and the dash looks like an Rx8 dash to me 🤔.......
What kind of car is at 4K rpm in 6th gear at 75? That’s surely insane? Unless it has like 9 gears then that’s pretty crap! And misfiring lol, whatever it is I won’t be getting one! Revs up to 8.5k but just as well, it would probably need that to go 100mph! I don’t even think my car sits at 2k rpm at 100mph in 7th
it is the the coils but i'd also get the shutter valves looked at "ssv" or even known as the runner valve on the intake manifold look and see if all is secured and tight. also while you are looking in that area, might as well look at the gaskets for the manifold as for they could be crumbling away. if you already done this and replaced the gaskets and the runners, i'd also check the e-crank and the maf sensor and also check all your grounds. it could be a fault wire touching metal somewhere in the engine bay. if you have done this too replace the intake breather tube. sometimes in time. on where the tubes go they seem to tear a bit and hot air seeps through the little crack which makes your car run poor, i know this isnt the situation on your part but this is just some helpful pointers to look at in the future if the car would ever fault on you once again. another helpful pointer to know, if you noticed your car idle under 1000 then thats a side seal blown and would need a whole engine rebuild. the reason for this to happen as it this car revs high, which makes every other object move at that same speed of the car and with that that makes heat, and as all rotor heads know rotaries love heat and they drink oil. if any other questions about this car please feel free to reply on this comment and i'll try to help you with your issue. i hope this sums up your situations
luigi martinez I'm throwing a code P0300 P0032 new BHR Coils new cat, once warm the car idle low 700 rpm explain you mentioned a side seal motor rebuild ? do you mean the Apex seal? I have not tried a compression test
TheTechCguy I’m not to sure tbh I just know not to buy a new Mazda unless it’s got a 13b quad rotor putting 1000hp just like mad mikes look that thing up on here mind boggling lol.
my truck only goes 10 mph climbing up a hill from a cause of misfire then it has a high rpm out of nowhere then i release from the gas then it drives normal it makes no sense!
damn if it's not you, the problem might be that your car can't even get to 5k that fast? of course if you drive a car with 9k on redline like that, problems like this are gonna appear sooner or later
I fixed da sparkplugs & the cables & still misfire from the 4th cylinder , I popped the hood at night time just from curiosity & saw a literal tiny spark from one of the cables. . Don’t know if that’s normal
cars been gone for 2 years. thanks though. blown oil seal was the issue

Coil packs, wires or plugs. ICM as well, but highly unlikely. My money is on the coil pack
Vacuum line....
its a rotary engine ...
lol wasn't it
I missed my RX8. Had that issue too but all got replaced.
MSA what did you replace?
Buddy there is Check Engine light blinking up. Take your car to the Service Centre...!
Yes, that was the *_point_* of the video.
Just like happen to me. Symbol check appears
That's an RX8 right? Mine is doing the same thing now.
theguy1991 its your ignition coils or spark plugs
it is the the coils but i'd also get the shutter valves looked at "ssv" or even known as the runner valve on the intake manifold look and see if all is secured and tight. also while you are looking in that area, might as well look at the gaskets for the manifold as for they could be crumbling away. if you already done this and replaced the gaskets and the runners, i'd also check the e-crank and the maf sensor and also check all your grounds. it could be a fault wire touching metal somewhere in the engine bay. if you have done this too replace the intake breather tube. sometimes in time. on where the tubes go they seem to tear a bit and hot air seeps through the little crack which makes your car run poor, i know this isnt the situation on your part but this is just some helpful pointers to look at in the future if the car would ever fault on you once again. another helpful pointer to know, if you noticed your car idle under 1000 then thats a side seal blown and would need a whole engine rebuild. the reason for this to happen as it this car revs high, which makes every other object move at that same speed of the car and with that that makes heat, and as all rotor heads know rotaries love heat and they drink oil. if any other questions about this car please feel free to reply on this comment and i'll try to help you with your issue. i hope this sums up your situations
luigi martinez I'm throwing a code P0300 P0032 new BHR Coils new cat, once warm the car idle low 700 rpm explain you mentioned a side seal motor rebuild ? do you mean the Apex seal? I have not tried a compression test
theguy1991 Better change the oil seals 😂
@@A17SNIPER P0300 is a random misfire. Get that looked at. P0032 is "Oxygen Sensor Heater Control Circuit High
"
What kind of car is it? I'm surprised you didn't even say what make and model it was.
TheTechCguy is a Mazda rx8 plus look at the rpm has Mazda symbol on steering wheel
Curtis Hest Yeah I saw the steering wheel but you didn't say what model it was. I was getting to that.
Well I did say it’s a Mazda RX8. The only thing good above t this car is the motor lol. Other than that I would junk the car
What year? There is a website called carcomplaints.com that can tell you what common problems your car has. From real testimony by real drivers.
TheTechCguy I’m not to sure tbh I just know not to buy a new Mazda unless it’s got a 13b quad rotor putting 1000hp just like mad mikes look that thing up on here mind boggling lol.
That had do be a bad coil but maybe the oil seal was also worn
Thats what happens if you own an RX8
my truck only goes 10 mph climbing up a hill from a cause of misfire then it has a high rpm out of nowhere then i release from the gas then it drives normal it makes no sense!
Did you ever figure it out?
The apex seals are probably fucked up
Its other sparks or fuel injectors
Flashing check engine means pull over lol
Seems like its a blown oil seal.
mine was just a ignition coil. quick $20 fix
damn if it's not you, the problem might be that your car can't even get to 5k that fast? of course if you drive a car with 9k on redline like that, problems like this are gonna appear sooner or later
I have same problem so how can I fixed thanks
Its a blown oil seal. I know cus i read a comment
Why tf is it like 5k rpm 5th gear 70 mph when my fiesta does just a little over 2k rpm at 70 in 5th also only here cuz this has happened to me
maybe an ignition problem or in the comp
Nothing serious going on buddy that cars screaming for help
Redline at 8500 rpm damn what car is this?
Changing plugs in a rotary engine rotary engines are notorious for oil leaks and that will fool out your plugs
I fixed da sparkplugs & the cables & still misfire from the 4th cylinder , I popped the hood at night time just from curiosity & saw a literal tiny spark from one of the cables. . Don’t know if that’s normal
check your ignition system and engine compression
i just wanna know is it safe to drive the vehicle ?
coil pack symptoms this for sure.
Maybe computer? Cause it’s almost exact on 5k everytime.
make sure to spark plug boot is good on
replace sparks plug cable , it will work fine
Rx8 huge nightmare
