99-10 HONDA ACURA V6 3.5 MISFIRE CYLINDERS 1 and 4
HTML-код
- Опубликовано: 25 дек 2017
- Hey guys! I just wanted to share a quick tip for anyone dealing with a 1999-2010 Honda Odyssey, Pilot, Accord or Acura MDX. Really anything that has the V6 3.5 J35A Vtec engine with a difficult misfire on cylinders #1 and #4 during cruising speeds. Especially when your trying to pass another vehicle on the road. Did you recently work on or have work done to the motor? do you have misfire trouble codes P0301 or P0304 or P0300? This may be related to a problem with incorrect EGR flow due to an incorrectly installed intake plenum cover gasket. I also show you a quick test you can perform to determine if this may be your problem.
Thanks for watching!

nice job Eric used to work in acura dealer happened a few times Austin Tx
Thanks for the video. Good knowledge to know. 👍
Thank you so much , I was having a headache with a 2002 Acura MDX. Had codes for misfire cyl1 and cly4.
Glad it helped
Thanks for sharing informative video. This is what happened to my 2002 MDX. I cleaned the throttle body on the top phlenum only for the first time. Rode test showed check engine light went on and the VTM4 light too after the install. Im glad I saw this video, I was thinking of bringing to the shop, but thought to myself I brought the problem.
Thanks for sharing sir!
Wow, that Gasket appears to be in the correct place when its on the wrong way. That is wild.
It looks more natural for it to be upside down which is of course wrong.
Good video.
Thanks for watching!
Thanks for sharing your video , I had the same problem. This helped me a lot, god bless you.
Awesome!
Great call on the gasket backwards/upside down! Like you say, if you didn’t know which way it goes, it would be pretty easy to install it the wrong way!
Exactly! Thanks for watching!
this crap should have been RECALLED by Honda USA !!!!
Great video man!
Thank you bro I’m gonna have to check that gasket again 😅🤦🏾♂️ I did a valve cover gasket replacement/engine coil/spark plug and a manifold kit gasket after install started up giving me a misfire code cylinder 1/2/4/5/6 smh on a 05 Acura MDX 4wd 😅
Great video! I took my cover off and was blown away by how much carbon and oil had deposited there. The gasket was actually on correctly though. I cleaned everything up, put it back together and started the car. It pretty much ran the same --rough. I had the codes read and then erased but they actually showed even more misfires on cylinders. Any idea what to do next? Thanks.
Gracias por tu video pude arreglar mi Acura mdx
Awesome video help me fix A car is a similar situation where it came from another shop I cares. I’m going to share it on my How to Automotive Facebook group page . Hopefully somebody find this useful.
Thank you for the support! I'm glad I could help!
also forget about the fancy IRRIDIUM skinny plugs ... bad!!!
Firing super lean mixtures, the "Double PLATINUM" plugs FIRE MORE CONSISTENTLY, engine runs SMOOTHLY with nice low end torque at 1,200 Rpm. No need to keep mashing the gas pedal to keep up with traffic flow.
Those skinny IRRIDIUMS electrodes are JUNK (random missfires) !!!!
Try this test:
- TRANSITION in P: PARK
- Ramp up engine speed slowly from idle up to 1500 or 2000 rpm
- If your engine randomly shakes, coughs, its got random misfiring (no DTC code).
These SparkPlugs are usually good to change at 80K to 90kMiles - They run okay pass 110K if your pushing your luck... but as the gap gets wider more misfiring cause a leaner mixture... not good for anything.
👍🏻
I had all of these flow paths clogged, the key is to look at the holes that go into each cylinder and align them when putting that gasket down. If you noticed, some holes do not match at all when put incorrectly; those holes must match up. I'm here because I have a very corroded EGR valve and I did not want to take them out, the issue that I have is that I read 1.86 volts, snapon says that it should read around 1.2v when engine off (indicating that pintle is closed). I manually power the EGR valve and I get the engine to stall but I only see around 3.5 volts for the current position. The issue that I have are misfires in cylinders 4 & 6 and sometimes 5. I replaced the PVC valve because it was open (pintle inside was loose); I don't know if that was my issue for sure but I still feel a slight misfire but no check engine so far, I think it may come back since the EGR being slightly open is also contributing.
VERY helpful video.I have been dealing with a check engine light for cylinder misfires 4,5 &6. My mechanic has looked at my car several times for the check engine light.Everytime he tells me its fixed and a few days later the light is on.This is definately something i could try out.Do you happen to have an email i can possibly run a few questions by? Im not sure where to look next if this doesnt solve my issue.If thats not something you do thats all good.Thanks!
I subscribed because of this video! I’m going to remove that cover, make sure the holes aren’t plugged and doublecheck gasket installation. 👍🏽👍🏽👍🏽
The squares in the EGR gasket have NOTHING to do with diverting the gases!!! The round EGR hole cutouts in the gasket are offset, and if you install the gasket backwards, the EGR ports in the intake manifold will be blocked off.
What are those 3 lines with black caps connected to the front of the engine block called? One of mine blew off while driving and now my car sounds straight piped.please help.
Good one 👍
I keep forgetting the EGR as a cause of misfire. This one is odd, not really sticking open or sticking closed....
100% same thing happen to me - my dumbass me put the plenum gasket wrong. Thanks brother !
My 2010 Honda 3.5 fouls out the spark plug in cylinder number 1 n starts miss firing but only that cylinder I have to change the plug every month apparently it is a common thing does anyone know the problem n fix
EGR flow > lean condition > random misfire.
(Not cylinder specific misfire)
Wondering if anyone can help me with my frustrating misfire in my 2008
acura 3.5l v6 172k. It only misfires when cold or sitting for a lil
while. When it misfires it only lasts for 5 to 15 seconds then goes
away. Things iv done: replaced all the spark plugs and coils. Replaced
all the fuel injectors and did a valve adjustment. Cleaned egr and
intake manifold. Put in new pcv valve and map sensor. Sometimes it will
throw random misfire p0300 or just a #5 cly. misfire. Then some days it
wont misfire at all. Im lost. Please help!!!!
you've done more than the basic would call for 👍🏻👍🏻
Get a scanner to LOOK AT LIVE DATA for your engine fuel trim: short term, long term.
Without that you ate blind as to why its misfiring !
I bet you will find your fuel trim is too lean because engine is not burning good enough.
- Fuel rail pressure regulator
- Crappy Iridium plugs
- OEM O2 Sensors
Using a scanner will help you see what the engine computer is doing.
👍🏻
I have an 02 Acura MDX an only has a miss fire at aidle
If you dont have any DTC Code then simply replace your plugs with "double platinum" (NOT the skinny Iridium pin). This curred my random misfires near idle.
if you get codes then diagnose by
moving spark coils Front to Back to see if code follows bad coil !
👍🏻
I have a 2004 MDX, ive installed new spark plugs and replaced bad coils, but I am still getting a hesitation\pull back when taking off from a dead stop.. I will try to clean the EGR Ports and remove EGR Valve entirely and clean it out.. But has anyone experienced this issue before?
hey did you figure out what was the problem afterall ? My mdx 2003 has the exact same symptoms you're describing here. Thanks
U should check the coils
Bad ignition coil for sure, I have the same issue end up cylinder 1 ignition coil is bad
Bro thats old is common on hondas egr and idle air control for misfire working on cars is not rocket science
