- This video will give you step by step instructions on checking and cleaning the engine EGR ports. This is a very common problem with regards to check engine lights and misfire DTCs (P0301 thru P0306, P1399, P0133) You should check for fowled spark plugs and ignition coils along with this procedure.

Just did a valve adjustment to 02 acura mdx same engine as yours put everything back car still got misfire couldn't figure out why opened everything up did valve adjustment again still check engine light came on looked at your video this morning realized I had the egr gasket on up side down, thanks for your video may the Lord Jesus bless u for helping me!!!
2004 Honda Odyssey - A Week ago, a mechanic replaced the EGR valve and cleaned up the Intake manifold passages, and they were plugged severely. Cleaned to be sparkling clean. Installed the gaskets and buttoned up the intake maniforld. But the TCS and CEL lights came back on, and diagnostics said same as before this upgrade which was random misfire. Then I watched this video which said if these lights come on check to the top gasket if installed properly. I checked it just now, and found it was not installed properly, as the holes for passage to the EGR were covered by the gasket. That was a joy to see, because of the alternative. So I turned the gasket upside down, and buttoned up. The dash lights are gone, but I still have to drive it for a while to be sure the lights do not come back on.
Thank you Edward Naso II
Was about to get rid of my 2000 TL 159,000. Instead I cleaned my ports in January 2019 and it misfired a couple of weeks later. But it hasn’t misfired since. Thanks for the video the TL lives on!
You my friend are a saint. You've probably just saved me hundreds of dollars taking my car to the shop. I took it in the other day and they couldnt figure out what was wrong or what was causing the misfiring, after following they're recommendations I ended up spending the money and buying OEM (NGK) plugs and installing them myself. After all that I still had the same issue even after the new plugs, I had misfire codes in every cylinder and also a "Random Multiple Misfire" code and after watching this and checking out my gasket it was indeed backwards. Swapped it back the correct orientation and PRESTO like dark wizardry it's running like a CHAMP again!!!
THANK YOU SO MUCH!
Thanks so much Ed. My girlfriend's car had a bad coil and clogged EGR ports. Running smoothly now!
226,000 and still going. Knocking on wood every day. Thanks for video. I'm going to have mine cleaned this month after replacing plugs and coils this week.
It's been up for 7 years but thanks so much for this vid!! I had the EXACT same issues! Even from the gasket being upside down. Thanks!
I had cleaned my intake and EGR ports about 2 years ago and thought no way they were the cause of my p1399 code and rough engine/misfires, but I followed these same steps to clean mine again just now and the rough idle went away and no more misfire. I was surprised because it wasn't even that gunked up because of the previous cleaning. But this helped for sure. THank s
Thank you for the video. This was exactly my problem. It would have probably cost me $150-$200 with the mechanic and it cost me $10 and 1hr of work but totally worth it!
Great Video, I have had my check engine light on for months. I installed the brace like in the video and now I’m light free! Thank you very much for posting this. It’s very much appreciated!!
I found out that the EGR valve code that was popping up is associated the random misfires. I unplugged the coils one by one while the car was running and found the one bad coil that caused all the problems. Thank you very much for your help!! I was soooo worried.
Mine was installed upside down as well on a 2000 TL. I was so close to trading this car in because of this issue. Thanks so much for your video it saved my ass!
Thank you very much for sharing!! I recently purchased a 2000 TL and this procedure, along with a spark plug change made all the difference in the way it drives.......really enjoyed the post. Thanks again
Thank you so much for this video! I just cleaned the channels out on a 2000 Acura TL that was giving misfire codes for all but one cylinder on its 3.2L V6; sure enough, all the channels were clogged except for one. Bravo!
Great lesson my guy. I always said that TH-cam’s my professor. Who needs college when you can learn step by step, hands on with demonstration. Research is key if done right, if still not positively sure, just look up one of the professors on TH-cam. Hey, thanks and keep learning and teaching my guy.
Hahaha words of wisdom! You're so right, TH-cam has almost everything! Glad I could help :) good luck with your project
OMG!!! my car wouldn't start after I cleaned it. So a mechanic came over and cranked it and help the gas pedal down all the way until it started!
He said I did a great job :) and explained what he did for future reference.
Woop woop!
This very informative video really fix my Acura TL 2000 misfire problem, I have to actually do it twice since the ist time I only did clean 80% of the EGR port, have also made the same mistake by returning the clean gasket upside down like originally found. 2nd time , I did a really thorough cleaning....like this video showed.put all the cleaned parts back. run the car for 20 to 30 miles and my check engine light just disappeared without resetting. I save money and have peace of mind driving my car, he now runs like a champ. without fear!......Thanks Ed and more power to you!!!
:) glad to have helped you!
Just finished watching your video and cleaning my 2000 3.2 TL's engine EGR ports and my gasket was also turned the wrong way covering the holes. Hopefully mine doesn't throw anymore codes. Thanks for the video.
why post before testing it?
Twoo_Wheelzz glad to have helped
Twoo_Wheelzz glad to help!
Thank you, glad I saw this easy fix before jumping into a valve adjustment. Replaced plugs and coil packs but still have code showing miss fire despite running much better.
these valves are non adjustable
have a 2005 acura mdx losing power when the maw-4 light comes on do u think that cleaning the egr ports will help?thxs
Thnx for the vid because my 01 acura tl is having 4 misfires , this helps
Edward Noso,
Thank you very much, I watched your gas cut video, my car had the same problem and with the help of your video my car's problem is solved. I changed the plugs, coils, cat lick converter and oxygen sensor. Your video helped me a lot many many thanks to you.
common issue you identified, i just looked at my the other day, they looked like your finished intake. my car has 170k (2004 acura mdx), just replaced iridrium spark plugs i got online for $9-each, coils look fine (brand new), i also bought mine second hand. coils are cheap, i saw ebay/online as low as $8/each. great video!
Thanks man, car idling so much better now!
Thanks Edward, worked like a charm. Went thru all the stuff you mentioned 1st. Easy as shown.
Video Very Helpful , Going To Check Mines In The Morning . Like The Other Comments A Shop Replaced My Spark Plugs And Coils. Now This I Can Do Myself . Appreciate The Time You Took To Post This
glad to help, it's an easy process that always fixes the problem! good luck
Found the problem. I had to keep pumping the gas to get the car started. Engine started but it kept misfiring. It ended up being an ignition coil which I already replaced. Thanks man.
My intake manifold looked just as filthy as yours when I removed and cleaned it. I didn’t know anything about the gasket possibly being upside down though! Maybe that’s why my Check Engine Light (CEL) came back on so quickly. I had enough been able to find anything else wrong. I do hope this fixes it! Thank you!
hey man great video! to bad didn't have camera man lol...anyway ima be doing that first thing in the morning all thanks to your video....wen you did clean the egr ports is there another end that the sludge drains out of? thanks again for great information
Hahaha! "If you don't have 10mm you should not be working on cars.." *drops bolt like someone who should not be working on cars* 😂
CHE3M.body obviously don't work on cars if you never dropped a bolt. Especially with a camera.
Adventureboy1231 haha thanks, so true! 😂
Thanks. I have a lready the same problem. I will try your method to clean and fix the problem of misfire cilinders.
Have a lot of thumb up.
sweet! thanks a lot for making this vid. I'm having a misfire code on my 03 TL. I'm working on it first thing tomorrow morning.👍👌
Evad82Arr6 _ great good luck, it solves most people's problems :)
Thank you. I just bought a CL last night and it's misfiring. I got it for cheap so I was hoping it was an easy fix like this sounds like it might be.
great to hear it! let me know how it works out :)
awesome tutorial!! Thanks!!! I'll try this before replacing coils/plugs
So many people suspecting the ignition coils first. With these 01 and 02 acura/honda the EGR system should be your first stop. Clean the entire system from the PCV, ports down thru and to the EGR valve (and it's ports and pintle).
Know how to test a coil first before condemning and replacing. Not saying it's never ignition related but that on these model years the EGR is more likely.
Those were all cleaned and still have the same problem.
Stores did not have ignition coils.
Swapped front left coil to right, right to left: no improvement.
Praying that ignition coils will correct the problem when I get them.
Denny chuya, this is a video explaining step by step the actions required in performing a technical bulletin posted by honda/Acura..of course the egr valve should be replaced at scheduled service intervals however the dealer posted a bulletin about this service in response to misfires that were difficult to diagnosis as a result of the egr port clogging. If your 3.2 motor is not in the years specified in this video it will not pertain to you as the ports have been redesigned...someone else also posted another comment about talking about tight valves and a MAF reading: that comment has no relevance to these motors as the valves on these motors are non-adjustable. Hope this helps everyone
Thanks for doing this video man, it fixed my misfires
Thank you for the video Edward. So this procedure took care of your misfire after all? Thanks
Dave, try driving the car....white smoke only comes from coolant (which you should not have been loosening the head bolts if you followed my instructions so your fine) or from excessive cleaning fluid down the ports, which(if the case) will burn off faster If you drive it...take it for a 5 mile spin and see if it stops, if not let me know I'll help you further
I tried this procedure. Thanks for your video. Also, I cleaned off the ports and gasket; put everything back together, reused the old gasket and set it in the right way; and also did sea foam right after. Nothing changed for me however. Still running rough and check engine light on. I have a 2003 Acura TL-s. Everything was working good until a few days ago; I changed the plugs last year and had no issues until now. But I have never changed the coil packs. my code is P1399. Can it be anything else? like the idle air control valve?
sounds like a bad coil...try idling the engine and one at a time disconnecting each one. the engine will idle much rougher after disconnecting a good one. keep trying this until no change is noticed after unplugging a coil and that will be the one requiring replacement 👍 ..of course a proper diagnostic tool will tel you which one but this is a great way if you don't have the right equipment
thanks. it was one coil. i replaced all of them. we back riding like an acura!
+David Johnson, that's great David, happy to hear it!
Can I use acetone ? Instead of break cleaner . I’m cleaning it right now let me know thanks bud
I have a 2005 acura tl that I just bought. And it misfires too. Do you think this could be my problem too? Please let me know, thank you.
Another very common cause is tight valves. Most of these engines will suffer from many misfires if the valves haven't been adjusted. A quick easy way to check is to find someone with a scan tool and at idle with all accessories off watch MAP voltage. It should be no more than 0.90v you can also do it with a volt meter but you need a wiring diagram.
Hello....good vid. I just bought a 2001 cl and I'm going to check this. What is the name for the gasket if I need a new one?
what is the name of the gasket that was installed upside down? I am going to start this project tomorrow. thanks
thanks a mill just did this job to my 01 acura CL earlier today. Gotta wait to get a jump my battery was dead before i did it so i wont know if this will clear my problem or not. I didnt do anything to the egr vavle so i dont know if i need to replace or clean that as well but i will say that my ports were beyond clogged and i mean every channel and the length of them were clogged so crossing my fingers and hope this gets me back up and running.
hey Marco, I'm positive you will see a drastic improvement!....good luck with the jump, glad I could help.
+Edward Naso II (Naso Pools) no prob bro thank you for the vid. I got her all patched back up so far so god sounds runs feels and drives a whole lot better so for anyone having misfire sputtering and loss of power issues ig you've tried everything and its still not working try this and its super easy and i do mean super.
+Marco McClure . thanks for the nice post Marco. I'm glad it worked out for you
i have the same. problems with my 01mdx i did afull tuneup still gives me the coeds hoping this. will do the trick
Im about to do this to my 02 tl type-s & get rid of the vibration, misfire problems.
awesome! thanks. did you have p0455 evap leak top?
Thank you for this video. Auto zone suggested the same things as you started with. I saw this video and was like hey let's check it out. What do you know it was backwards and dirty. $3 and 30 mins later problem solved. Double checked plugs being it was a cheap replacement but they look ok for now.
clion520 that's fantastic! I'm glad it worked for you :) it took me forever to figure out this misfire problem, it's nice to hear I'm saving people some headaches and time. thanks for the reply :)
I am curious to know why you chose to solve the problem with the most expensive options; i.e. plugs and coils, first instead of doing the air plenum cleaning first.
Mileage would dictate replacement first. Coils and plugs should be replaced every 100,000 mi. If you haven't replaced them that's a good start You will get better fuel economy. These are known to fail
OBD II connector is located in the tray/dish area between the seat heater switches. There is a little tray/dish like area in front of the gear selector, all the way down under the nav unit. You will have to open it / take off the cover.
Great video! Without realizing it, my son's car went a year (10,000 miles) without an oil change - YIKES! The engine light and caution light went on this morning, and it drove very rough. Oil change light was not on. Checked the oil, and it was very low. Put some oil in it and drove to Valvaline, where they checked the codes. Misfire on 1,2,4,5 cylinders and P1399 code. Have a 10mm ratchet - have done electric and plumbing, but not cars. Should I try this, or take to a dealer??
My,gasket was on backwards too i been lookin for one but i cant find them could you tell me were you bought yours please
Shindemon33, it sounds like you have an air leak, I would remove the top again and check the gasket make sure none of the seals are crushed. You may need to replace the gasket and when reinstalling make sure you torque properly in a criss cross pattern
Great video. I have a 2003 MDX and keep on getting the multiple cyl. misfire. Seemed like it went away when I put in the fuel cleaner but it came back. Any suggestions? I got a 3.5, so it a little different, do you need to change the oil once you clean it with the brake cleaner?
I would perform the steps I point out in this video. it should resolve this problem you are having
How r u what did u use to clean the egr port on the engine
had my knock sensor replaced .. got an "engine lean" code.. then it went away but car still feels hesitant.. changed spark plugs.. hestitant problem still there.. very minor but still there.. do u know how i can fix that?
Glad to be of help to everyone
Thanks so much for the post! I saved the me money and time.
great to hear it...happy to help
I have clean up everything, but still kick in the P1399 code. Took the EGV off and try to clean it nothing work either. Really need help on this.
Could me cleaning the ports have exacerbated any problems that already existed?The car was misfiring prior to me cleaning the ports, hence the reason I looked up your video.
Excelent im glad to help a fellow honda/acura driver! :)
Hello I just finished cleaning my 2002 acura tl but won't start do u have any clue what might be going on
Hello I have a question as well I'm gone post a link and hopefully you can tell me what's wrong
Does this really work? My 00 tl has recently been misfiring and just idling when I try to accelerate unless I put it in D4
Do you believe this also occurs with other newer years? (Upside-down) gasket. Maybe 05 and up?
I sprayed carb cleaner in the far right side of the manifold, would that cause the car not to start after the valve and ports have been cleaned??
Hello I have a p1399 misfire and I’m worried I haven’t moved my car in days
Fantastic video!
Thanks! Very informative!
I did this, thanks for the help. But now I don’t have vtec, any ideas would be great
Possibly bad camshaft position sensor
The intake manifold cover was on backwards too!
I used break cleaner. It was starting prior to me cleaning the ports.
My car was misfiring. I found the bad coil and replaced it. I also changed all of the plugs. I saw this video before a started, so I took the cover off and it looked just like yours. I Cleaned it up, and then had to crank the car for about a minute to get it started. Now it runs great. But Im curious why I had to crank it so long to start it initially.
Maybe the air you let into the top of the motor? Maybe the cleaner you used made it have a rough start .. don't think it's anything to worry about
same thing happened to me.
Mine did the same thing. After a few tries i decided to push the gas pedal, though it is fuel injected; that seemed to work. Unfortunately, i still had misfires, in fact, i had more than i had when i started? Still investigating.
Should I worry about getting break cleaner in the manifold when cleaning the port holes? Won't it get into the the engine and mix with the oil. Thanks
What about 04' models?
I have a hesitation at around 1750 rpm below 40 mph only...Doesn't do it above 40 mph.
Car jerks until to give more gas or let off throttle. Feels terrible
Seems like a bad coil, dealer will not look at without a CEL on. I made it go on once while beating on it and there were misfire codes. They swapped coils around and still same issue. Im going to pull the coils out and check for a bad one.
Plugs are 6 months old. Im afraid to even open the cover on my engine like you did and clean it.
I had a transmission issues. Trying to get it covered under warranty now.
Going to do this anyway because I have gotten P0301 and P0305 codes before.
Can you tell me where the OBD II connector is located on my 2001 Acura CL-S 3.2. Ran the battery down listening to the radio, now having intermittent engine shutting off but restarting going down the road. The dude at advance could not locate the connector to get a code for me. Battery connectors have been cleaned, believe atleastba contributing factor. Thank you for any and all help.
If my engine light goes away after this. I love you.
ED,
Do you think I can sandblast the underside of the cover where the EGR groves are?
I have a sandblaster that will being it a nice clean bare metal.....
After performing your procedure, the car would not start up. It starts cranking but the car will not completely start. It sounds like it wants to start, and it is about to, but does not. I cleaned the gasket as well as the egr ports, could that be the problem?
thanks for the video. I cleaned everything out and put it back together. the gasket was in the right spot but some of the channels were completely clogged. once I put it back together and went to start it nothing happened. the starter is turning but I'm not getting any compression.the engine started before I cleaned it but now I can't even get it to turn over. my best guess is the spark plugs got some moisture on them and so it's not sparking. is that a possibility? took it apart again to let it air out. any other suggestions? The GF is pissed I effed up her car.
Robert Der I do not mention in the video but you have to reset the car's computer. The computer will recognize different airflow and will have to be reset. If you continue to try it will eventually start and relearn on its own but I might take a couple minutes to start without resetting the computer period if you don't have a computer try disconnecting the battery for 15 minutes. the spark plugs could not have gotten well keep trying you will be fine as long as you reassembled and reconnected everything properly
worked perfectly. thank you. just saved me a world of hurt.
Robert Der LOL glad to have helped sorry about that scare I wish I had a way to update the video without having to repost it to let people know that. It is a common comment I get here. Once those ports are clean there is so much more airflow the computer doesn't know what to do and it takes a while to recalibrate itself. The reset solves all those problems. Hopefully your misfire issues are resolved as well
Acura 2000 TL...engine as per this video. Blew spark plug & melted coil boot over spark plug. Now I cannot screw a sprk plug into the well. Any suggestions?
so I cleaned the egr ports as well as changed out my coil packs and spark plugs but the check engine light is still signaling a misfire?
I want to say thank you for answering my question but I still don't know what to do like essay the first time of change is my plug the coil the oil and also change my pressure regulator and my fuel filter I'm still getting the same result this is the number I am getting p1201 1202 1203 1205 andpo300 and1697 , what to do maybe you can help have done everything I can
I really appreciate your business
Thank you
That does not sound like the problem. what did you clean the EGR ports with? Hey no start issue I would check all your spark plugs and your coils again. Let me know
hey Edward great video. would this process work with my 1999 3.2 tl ?
absolutely!
+Edward Naso II (Naso Pools) thanks bro, Have a great new year
+D Cast thanks same to you. good luck with the process. if you already checked your coils for proper operation and still get a vibration around 60mph and misfire codes this will fix you up good as new
+Edward Naso II (Naso Pools) well ,I had all my coils changed by mechanic, n the plugs n egr sensor. so I'm hoping this clears it.
+D Cast ugh, sorry to hear it..this was probably the only problem. a lot of mechanics unfortunately make that same mistake. when the code reads "misfire on all cylinders" many mechanics will look at the mileage of the vehicle and assume all the coil packs are weak and worn out and need to be replaced... this is a common misconception. coil packs are either good, or bad, not weak or in between, their design doesn't allow for that. besides a quick continuity tests tools would be unable to test their voltage accurately. ....rest assured, this will fix your problem!
Yep, thanks for the vid!
I have a 1999 tl. How similar is this problem to mine?
After performing this cleaning precedure my 01 tl started to jerk after letting off the throttle. Any advice? Replaced front mount
hello good afternoon friend, I am having a problem with my Acura Tl Type S 08. sometimes the engine light comes on. take my car to Auto Zone and made a diagnosis and OBD code P0174 appeared too lean Fuel sistem bank 2. I want to know where the MAP sensor to clean, and also buy the air filter. I'm starting with the basics. Besides my car has a sulfur smell when I go fast on the freeway, I have informed and can be catalytic, but this car has 3 catalytic, two in the engine one in front and one behind and one in the line of exhaust pipe . Not if the term refers to the Bank 2 catalytic front of the engine. Seeking recommendations to fix the problem because they do not have much money to fix my car. Also buy spark plugs to make it a Tune Up. And finally I added injector cleaner the Lucas brand in the gasoline tank
Code P0174 possible causes
- Intake air leaks - Faulty front heated oxygen sensor - Ignition misfiring - Faulty fuel injectors - Exhaust gas leaks - Incorrect fuel pressure - Lack of fuel - Faulty Mass Air Flow (MAF) sensor - Incorrect Positive Crankcase Ventilation (PCV) hose connection
03 TL-s, p0301-06, p1399, but not 0133. I'll try this out in the morning, but, im having constant misfire on two of the cylinders...hope i can get results
Edward, tried this, cleaned everything out real good, now I have white smoke, let it run for about 20 minutes, and still billowing out....help
Thank so much for your nice details video
chanhduc phung glad to have helped! hope it works for you
I'm having misfires on my 02 tl type s, had misfires before and took it into the shop, they checked plugs and injectors, both brand new.. Eventually it started working again but I don't think they even knew why. Now a few months down the road its doing it again, rumbling, low idle ect. so i'll give this a try in the morning and post back if it works.
let us know ! looking to do this soon aswell. thanks ! :)
eddie lima Wasn't a help for me, took it into the shop and its getting a new coil in the morning :P
Did the coil fix the problem?
King Pharaoh yes, 2 could went bad In A span of a couple months, I wish I knew it would have saved me a few hundred dollars changing them myself
I have a 2000 3.2 tl has 216 3542 on it and fot all the coils and egr replaced and it is still reading missfired. And it sometimes it won't start and it it doest i have tp hold peddle all the way to floor and it wont rev about 1000 if i let go pf gas it dies out them i start again hold gas to floor still wont rev fo3 a bit when it start to rev it back fires a few time then if i let go dies out . This happens a few time before it stay started and it smelld like it is flooded and drive fine jusy when it is being started after a long drive
Just want some clarification -
1. What should I use to clean this? Non-Chlorinated Brake Cleaner?
2. I pulled off the cover and it seems like there is a lot of moisture in there. Is this natural?
bsumaverick non-chlorinated brake cleaner or carb cleaner are fine. There should not be moisture inside check your air filter and all your intake tubes to make sure there is not a break. also that might be a sign of a bigger problem, possibly dirty injectors or non fire ignition coil , or bad valve if that moisture is unburnt fuel
Hi Edward. Hoping I get a response from you. I have a 2000 TL. Car has 230K miles. Been running like a charm as I have taken good care of it. Past few months, on occasion, I would have trouble starting it. Then when it did start, it would run extremely rough at idle. After giving it some gas, I could on occasion get it running fine again. Other day, car ran fine. Then went out and it wouldn't start at first. Once I did get it started, its certainly running very rough, not much power, chugging and the TSC light is flashing. Would clogged EGR ports be causing this? I haven't had chance to hook up to computer to see codes yet. A few years ago, I did have to replace some coil packs. To my knowledge, the EGR ports have never been cleaned on this car. Your help would be appreciated!!
sounds like bad spark plugs. change them first... it is a very good idea to clean the EGR ports as well. If it's never been done with that kind of mileage it most certainly needs it if you're not running 93 octane consistently. Let me know I'll be happy to assist
THanks for the reply! I am changing spark plugs as well as just doing the coil packs as well. I'll know today as I had to order the coil packs, if this is the issue. As I may have mentioned, I did clean out the EGR ports as well. Question is, if I do all of this, and it still does the same, which is barely running, what would be the next things to look at, check? Thanks again!
Maf sensor...definitely would be next
Where is this located on the TL? Others I have done, were within the air cleaner. On this car, no sign of it there?? Would this really cause the car to run this poorly or not even start? BTW, I changed plugs and coils...didn't help.
nice video my acura mdx 2002 is workin good now
Jeobani alvarez did you to the same procedure as he? my 2001 seems to be misfiring but I have no codes
leonor rincon I first desconect the battery after clean the egr and change the spark plugs my acura mdx 2002 working nice
ok thanks for your quick response
leonor rincon hola leonor lo primero que tienes que aser es desconectar la bateria y aser el mismo prosedimiento asi como lo esplica el video yo lo hise y me funsiono de mil maravillas.
Tambien chequea las bobinas a veses pueden estar una que no tira buena chispa.
Primero puedes intentar desconectar la bateria por 15 minutos para que se reinisie la computadora. A veses no ay ninguna falla
