Hi, I am Francisco.
We are a group of vehicle enthusiasts looking for Car meets, car shows, drag racing, roll racing, New cars, etc,..
after replacing the spark plugs on this N63, the misfire stay on cylinder number 7. the coil was good, the injector was good but still misfire.
the leads to a internal engine failure that can can by a low compression in the cylinder No. 7
by pressure testing the cylinder you can tell from where the leak is coming from. at the end, the leak was found in the intake valves.
but, that is a problem because, to really clean the intake valve you have to remove major components of the engine.
this could be a problem, but, there is solutions. using a intake valve cleaner can help as i showed in this video. so now you now, if a misfire never goes away, clean the intake valve
VERY IMPORTANT: MAKE SURE TO DELETE THE CODES OF THE COMPUTER BEFORE STARTING THE ENGINE OTHERWISE THE PEOBLEM WILL STAY PRESENT.
intake valve carbon build cleaning can help to fix problems like
drivetrain malfuntion errors
misfires
low power
low fuel economy
unstable idle
check engine light
smoke for tailpipe

Muchos Gracias, Señor Francisco! I really appreciate your N63 videos as well as your mechanical ingenuity! Best Regards!
Thank you for the n63 videos.
Thank you for the videos keep them videos coming on the bmw N63 engine
Thank you keep making videos !!!
Man you just saved my life ...thank you so much
Brother francisco amaya you are a doctor for N63 engine
Thank you so much for the great video
I am from srilanka... really great video
Thank you! Worked for me as well on N63 engine. Cylinder #7 Misfire!
I also have an n63, having a misfire on 4 , just wondering where did u spray the CRC cleaner and if u removed any ma sensors
@@aaftlifemuzic I sprayed it into the intake boots on either side with the engine running AFTER the maf sensor. Just loosed the clamp and slide the straw into the boot
@@Johnathan_Waters I'm trying this as we speak connected the compression gauge tester in fear of no compression and to my relief I had 175 compression on suspected cylinder!!!!! 🤗So now time to give this bottle a try!!
@@jrpcoins Just to add some more updated info to this, the particular engine I was working on before ended up (again) with misfires, and the owner of the car continued driving it despite my warnings (and the engine running like total crap) and ended up with a broken timing chain within a month or so. So, CHECK YOUR TIMING CHAIN!!!! Valve timing being out due to a stretched timing chain can also cause misfires!
Great vid

Hey man! U need to clear adaptations in DME after your procedure, so DME misfires counter will be zero again.
Nice video, thanks!
I have a missfire on cylinder 4 on my n63. I changed plugs and the coil is good. Trying to figure out where to spray the CRC cleaner and if I need to remove any sensors
You are a patient man. Lol.
Thank you! Plan on doing a carbon clean on my F02 but was wondering where the best place to inject the CRC was. Please keep the N63 videos coming. Interested in seeing coolant replacement (including intercoolers) and transmission fluid.
Did you do this procedure? if so did you do it on both sides of the engine? i have an n63tu motor, and was wondering if i should run a can of this between the 2 sides, as i do get a DTM and misfire message rarely...
@@ShailenPatel22did you end up doing this? Also curious if I should do both sides like you mentioned
thx
I don't have a problem with mine but I will do this as a preventative measure unless anyone advises I shouldn't
Hi May I ask how to keep rpm running steady at 2000rpm while spray?
Hi
I have the same engine and sometimes when accelerate a misfire on cylinder 4 pop's up.
I checked the compression test and the results was fine.
Just one question I saw that when you did the HPFP test it shows 100 bar.
My engine shows 50 bar.
Is this the problem?
You are knowledgeable abt the n63 engine. Where ur shop? East coast?
I will try the crc
Do you have a shop I’m having problems with my 550li
Is this the intake boot that you are spraying into?
How can I use throttle cleaner where can I put it in
Thanks for the video. I’m having this exact scenario on my 2016 750i xDrive. Replaced all plugs and coil packs to no avail and found no compression in cylinder 7. Picked up the spray today, OBD2 will be in tomorrow. To clarify, I do the spray, then clear the code before restarting, correct? Or do I clear the code before doing the spray?
How did you make out?
Clear code before spraying. If it works light won't come back on. If it does come on then I recommend having walnut blast the valves, which is the proper way. Quite expensive but the come up like new.
Thank you for all the videos they are very helpful. I have a question on my 2012 750i xdrive, I unlock all my doors with my key fob but my driver door does not unlock also all my other doors do not lock. Any idea what I can do ?
Ivan Quirino hi check if all the doors are closed check the other key fob not in the car check for the key fob battery
@@MsSheikh111 I only have one key fob and have changed the battery on the key fob multiple times. Thank you for the suggestion
I think this is something that can be coded with an enet cable ($25 on amazon, will need an ethernet to usb-c or ethernet to lightning adapter too) and bimmercode app on your phone
It's the fuse. I had the same problem
Great videos man you are a genius I wish I could get my car to your shop.! I have a question. My 2011 550i show up a misfire when I push the gas hard over 50 or 60 miles. Any idea what causes this problem?. Also I turn off the engine and start it up again and the problem gone but it comes back when I force the engine. I will appreciate any answers thank you.
I had the same problem. I changed my coils and plugs. It runs great now
this happen because not using high octine gas, or use cleaner with the gas like lucas fuel cleaner
2nd can you should have done on bank 1
No oil change after?
Would it have worked better if you had sprayed the cleaner in at the bottom of or at the inter coolers? Then it wouldn't have as far to go to get to the intake valves. I don't know if the boost from the turbos would be to high but I'm guessing at that low of an idle and not under load it wouldn't be boosting to much
i got a 2011 750lixdrive 182k miles starting to get the drivetrain yatta yatta...replaced coils and spark plugs, problem comes back after a couple days if I let it sit it goes away, where do I start...had misfire codes, i think it may just be a leak somewhere
I know this is a fairly old comment, but it could either be the high pressure fuel pump, or it could be a partially clogged injector that is causing your drive train malfunction. I own a 2011 550i xDrive and had the same issue you are having on your 750li
Does the intake valve cleaner fix the driver train malfunction code?
Yes. If you have no other issues and it cleans them the drivetrain malfuntion will not come back
lol send me some of that blessed carbon cleaner😂 my cars completely f'ed im almost certain.
actually i just checked the compression of suspected cylinder (#4) and it passed at 175. but the damn code wont go away even after clearing all codes. i have yet to change the fuel injectors and have yet to hit it with carb cleaner
I need some help with my 08 750i twin turbo. Misfires jumping around. New plugs and coils. Compression on 5-8 = 200 cylinders 1-4 = 110 to 140
That is a low compression.
Maybe you have a compression leak in the internal components of the engine
@@IEEuros the entire passenger side has low compression. Maybe the Vanos solenoids?
@@IEEuros it will run right for a minute then it acts up
I changed the coils, spark plugs, and pcv valve on my 750i n63 engine and I'm still getting multiple random misfire. Any suggestions?
Injectors
My bmw x6M kept having manifold absolute throttle angle too low can you help pls
Did u fix ur issue? Having the same code
My gt 550 is in limpmode with code low pressure (fuel) bank 2 half of the engine misfiring... fml
This will happen again but I mean hey f it lol, better than taking off the intakes although I would do it on a 4 banger no problem.
Catch can. Problem solved.
how do you make your car hold 2k rpm when in park??
theres a 2nd person in the car with his foot on the gas pedal
Seafoam works better
Can I bring my car to you?
that particular year was garbage....the N63tu was a lil better....stay far away from 2013 and down....2014 on up much better improvement
also you are a genious
I think thats very bad idea,and dangerous for the engine...but its my opinion like 20 years mechanic
How much did CRC pay you guys? Lol
these engines are pure shit
