BMW E36 Rough Idle & Stalling Diagnosis
Вставка
- Опубліковано 21 січ 2017
- This video describes my diagnosis of a stalling bmw E36. Typically if the car turns over and idles rough or wont hold an idle it has either an air or fuel delivery issue. The first thing to examine is any check engine lights, afterwards check if the car will hold an idle with the foot on the throttle.
Many of these issues can be contributed to cracked air hoses or a bad ICV, MAF, or Throttle Control Sensor.
Bad sensors and valves don't always come up as a check engine light, which makes it a little more difficult to diagnose. - Авто та транспорт
thanks for this video i am a mechanic from the GAMBIA, WEST AFRICA. i worked on different types cars my neighbor a bmw e36 and it never hold idle. after watching this, i follow your steps and i have a good result
from gambia too nice too meet up here
Thanks for the review, I started to go down the path of the Mass air flow sensor and found the problem immediately, The hose to the Idle control valve had come disconnected. Back to normal operation ! Thanks
my BMW e36 94 model just been doing that, i changed 4 coils, sparkin plugs, air filter, cleaned the air filter box and sensor area, i started it, it was smooth like a babies ass, but the next day it started to stall again, i changed the fuel filter and fuel pump, shit, if i came here before lol it might be the ldle then, THANKS HEAPS BROTHER ,
i think you saved me from buying a computer code reader lol . i have been with out a car 7 days, .
Awesome video I just bought a 318ti that's doing this when cold I'll give this a go!
Save my life and money bro, thank you, you have a new disc🙌🙌
It works! Bmw e36 320i 1996 thanks alot :3
Your video saved my life today 🤣
How do you clean the metal mass airflow? everyone has videos of only the black plastic one.. do you still spray MAF cleaner in the metal one once removed the same way? thanks
I got 316i with a 318i engine the idleling is crazy I don't know what to do but I love him alot
I had/have the same symptoms. I replaced the MAF and that didn't work. Today I cleaned the ICV per your video and that helped for a few miles and the problem is still there. After more inspecting I see a hose broken from what I believe is the vacuum box. Would that be possible and how difficult is it to replace? Do I have to remove the upper and lower intake? Unfortunately, I can't post the pic I took.
very informative...thx
Great work my friend.
Thanks a lot!
I have an 1998 323i convertible. It runs great but I have began preventive maintenance on my vehicle. One of the issues is the window. You touched on a few of the issues in a video you made where you replaced the bushling (excuse my spelling) in the drivers side window of your brothers car. I would like to send you a video of my window while I trouble shoot the problem. I dont know how to private message on here.
Rico B send it to me on Facebook, bimmer craze
Hi! I need your help. I have a 1994 318i convertible. For the life of me I cannot Remove the blower motor. The passenger side cover of the blower box is pinned under the sheet metal. Seems to be an issue only on the convertible models. Any advice would be much appreciated.
Could you please tell me about the breading hose, the small vacum hose where do you put it inside. It is out on my bmw 318i
same thing happened with my IS . tha camshaftsensor was putting the ecu in protectmode . thanks BMW 4 saving my baby
Can you tell me more about that? I’ve had my thoughts about my 93 318i it will start run for 10 or 5 seconds then die and now it just idles and dies when you hit the gas and revs when you lift it up
@@blakecook1104 I have the same problem on my 318ti, did you find what is it?
@@blakecook1104 did you found solution? I checked almost everything, cleaned the icv etc etc, still does same as yours
good vdo thank you.
Hi guys I replaced my motor 316i e36 aluminium top the car starts and idles but after a few km cuts off and only starts once cold the mechenic says its the airflow is this the case or should I check something else?
I had the problem , tightened that idle screw and then problem went away , idling at 650rmp . What are you’re thoughts ?
excellent vid. TY. :)
Marcus Triton thanks a lot glad it helped!
Okay I'm just asking cuz I've done a bunch of stuff and I don't have any friends so any tips, tricks or anything like that definitely welcomed So car runs fine, gets up to temperature and then randomly decides to have jittery throttle that continues to rev when you clutch in and then at standstill it falls on its face catches itself rinse repeat until it stalls out now I have replaced the throttle position sensor. I've replaced the intake boot intake hose that goes to the ICV and the thing that allows it to connect to the underside of intake. I have cleaned the ICV twice makes the nice sound. And clean the mass airflow sensor and the issues still persist. I'm I'm so f****** confused man. You said there could be other things causing it and I'm like what are the other things I need to know?
hi i need help with high revs i replaced my head cylinder when the engin is hot the engin over rev i brougth down
I could use some help/pointers. 96 318i. 94k miles, 5spd manual. Car was running fine but 2 weeks ago the plastic water outlet failed on the back of the engine. All coolant leaked out as the large nipple broke off. A major pita to replace but I did it. At the same time I was thinking the similar water outlet on the driver side of the block could be just as bad. So i bought that as well and took the upper intake manifold off and replaced that as well. Changed most hoses too, incl. the ones to the injector as they were in bad shape. After that I noticed oil leak at cyl # 2 so I changed the valve cover gasket. As I was putting back the throttle body, I noticed there was a lot of oil smudge deposit around the butterfly valves, so I cleaned the batterflies and surroundings with kerosin (I had no carb cleaner left) It removed the nasty oil deposits and the valves seem to open and close a little better. No more sticky feel. I then put everything back and now I have a rough idle. It never stalled yet, but its rough. Like its too low, as if I tap the accelerator pedal a little, it smooths out. I drove the car today about 30-40 miles. It did feel slightly better after driving it but once cooled down, its really crap again. It hovers around the 700rpm range but rough, shakes the engine. Here is what I did so far as an attempt to fix it. I put 4 new NGK spark plug on it. I removed the idle control valve and cleaned it. It was not really dirty, but cleaned it anyway. The valve was turning freely and the whole valve seems ok. I also sprayed a lot of intake/throttle cleaner into the throttle body. I cleaned the Mass Air Flow sensor with the MAF Cleaner as well. No changes whatsoever. Once its revved, the car seems to be running perfectly fine, no hesitation, no vibration, smooth, power seems to be all there, no hard starting, no stalling. I did around 70mph the fastest and it was fine at that speed as well. No other issues but the idle being rough. Its almost like when you have a large V8 with a lumpy idle. Engine shaking, etc. Also, no check engine light, so I can't try and read codes. I tried spraying carb cleaner around the intake manifold, throttle body to see if the idle gets rougher or stalling happens but nothing. Also as the engine gets warmer, it gets slightly better. Still very bad, but a tad smoother. Its like 1 being stalling 5 being perfect, it gets from #2 to #3 and if you drive it a lot, it gets #4 but never smooth like it was before I torn everything down. I'm pretty sure I did something during assembly. It does not seem it just happen to go bad. Right before I started working on it 4 days ago, I pulled into a garage and smooth idle, etc. I ran it only for 40-50 sec as it had no coolant, but car had butter smooth idle. I ordered an O2 sensor, as I was going to change that anyway. I used BMW parts and NGK spark plugs. I appreciate any and all help as I'm a bit lost at the moment.
hey man i have the same problem but with a 328is u ever get it figured out?
Think we might have the same issue. It's got that v8 rocky feeling, but runs great except for the idle. Not sure what it is.
ever figure it out?
Hey! :) What is this 2nd bowden by throttle valve was go to AFM?
I have m43b16 in europe, but i have no this secondary bowden to AFM.
This is one issue upgrade, or original part?
Can u helping for me?
Good job.
Gerry Reggea thanks a lot!
Thanks buddy for sharing. I have too much fuel consumption problem with my 1997 318i. I changed fuel pump, oxygen censor and also cleaned up injector, but my problem remain the same. It is giving 4 km per litter of fuel. can you suggest me what to do. Thanks dear
Shaheedul Islam I had a problem with fuel consumption, and replacing the pcv and connecting hose solved this issue. Good luck
where to go if there's high hydro carbons? have a vacuum leak? what could it be
hello.. pl hel me.. my car(E36 328 WITH M50 manifold.) working good when its cold(normal temperature) .. driving -- engine hot- when I try to stop the car then the engine goes off .. idle valve cleaning .. not working oxygen sensors... can cause oxygen sensors engine off ??
thank you for this video. just what i was looking for!
Glad it helped, thanks!
Hie,,, my E36 318is does that but when i start it and give its little bit of gas its will be fine
Or if i start it for the fourth or fifth time it will be fine,,, can you help me out please😭
Bad camshaft Sensor gave me the same stalling regardless of throttle position.
My car suddenly stop while i'm driving , try to start it again , but it won't start again ,
Before it happen my car idling like it want to die
where does that small breather hose under the intake manifold go to?
Also true for e46 318i with m43
Good upload! The problem with my 1994 316i Compact is on repeat starts sand stops it idles very unevenly for about 20 seconds then runs as it should. Its a low mileage car - only 95 thousand kilometres. There's no missing or uneven running when driving or accelerating. Hot or cold engine, dry or wet weather, same thing. Only this rough idling for a short time but it doesn't cut out. Does this sound like a problem you recognise? - thanks so much in advance.
What was the problem?
Did you find the problem?
i have an m44. i need help finding that rubber hose that connects to the air flow meter throttle boot. its the rubble hose that id under the upper intake. would you know the part number?
Chris A _Operation Get Sexy 13711247031
My car runs stronger when the ac is off is this a battery issue?
man my e36 318i is without power. and on the test diagnostic panel, He gives me the code 1224.
in the manual means that it is defective in the intake air temperature sensor. but I can not find this part in the engine. Where is it located? HELP ME PLS
Patrick Galter its on the airfilter housing box with a connector attached to it
Friend, what engine does that m42 or m44 car have?
now I gotta go drag my 95 model 325i out of its resting place and check the ICV on it because I ran myself nuts trying to diagnose this issue. mine wouldn't even start and run at all unless i held the gas down and if it did start, i had to keep it above 2500rpm or it immediately died. and being a 95 and OBD1 I cant use the adapter and software from bimmer forums to check anything. it will only read OBD2 96 and up
really would have liked to see if that diagnosis did anything. i mean, it's cool to know where that stuff is but did the car turn over and hold idle?
freshmeatpopsicle it had a clogged icv, I had to pull the upper intake off and clean out the valve.
My bmw z3 1996 4 cylinder is doing the same thing but my car when I give it gas it does not rev up it just stalls do you think it could be the same thing or that fuel could be my problem.
Hey am having the same problem did you ever got yours fix
Where u based at guys?
What is that intro song Id ?
Hey man, you wouldn’t happen to have the OEM part number for the idle control valve would you? I also have a E36 318i 1995
I have replaced the PCV and am looking to fix this next.
This is the Bosch: 0280140549, should be correct number.
E36 Fanatics you bloody legend. Thanks mate! Hola from Australia 🇦🇺👍🏼

Have anyone ever noticed that the parts on a BMW that goes faulty is usually the parts they don’t make themselves ...like bosh, Lukas, Siemens, ZF etc.… these parts make lots of people think that BMW is a unreliable vetches but I’m convinced that if they BMW make all parts of the cars they make it would 10 to one run for at least 10 years before breaking down. just something to think about.
hm interesting point
@@Boz1211111 Bosch, Seimens, and ZF are companies that supply parts that exhibit a high degree of reliability; Lucas is another story.
Does this engine need regular 87 octane gas? or does it run better on higher grade?
89+ octane
This car run on gas or petrol?
Does anyone know where I can get the hose for the icv that runs to the intake boot?
Online ebay or Amazon make sure I type every detail ur model
Hello, I am writing to you from Turkey. my vehicle is e36 m43b16. the hose coming out of the flow meter bellows remains empty. I don't know where he went. can you help me?
Have you figured it out I’m looking for where it goes
Almost always an unmetered air hose vacuum leak.
Mass flow to IAC or IAC to fuel injectors.
Just my personal experience
One last thing I noticed a small tube under the upper intake manifold to the right of the logo, I cannot find where it goes
Does it come out of the lower intake manifold? Actually it could be the one that attaches to the vacuum control valve. It's a little black and white valve that runs up to the upper intake from the lower intake if I recall.
It's about 1 foot but bent in a few places. Can I have your phone number so I can send you a picture?
I found your Facebook page and messaged you the photo there
brandon rost its for the Disa Valve. Its goes to the check valve of it
Naush Rhyman need to follow up on this specific topic. I’m lost to which nozzle it goes to. There’s 2 coming from disa and another nozzle looks like could go to secondary air pump. One of my hoses were very brittle and couldn’t be used and now I’m stuck !!
my icv was also bad, cleaning it didn't solve it. the idle was unstable for a few seconds as i first started the car (cold) but then it would go normal, and it would just stall when starting the car hot. after checking the price of a new one (around or over 200€, and wasn't even in stock, probably have to get it straight from bmw themselves) i decided i would risk 32€ instead for an aliexpress/ebay one, and it turned out to work perfectly! so yeah, go for one of those if you ever need one lol, unless you want to swap the whole intake for the newer m43b18 intake which doesn't use that system, like one of my friends did, but that will cost even more, so i didn't bother. fixed for 32€, brand new valve, can't argue with that 😉👌
Yes my brother got lucky with an EBay ICV and only paid $30 something dollars for it and it worked perfectly!
My 93 325is isnt stalling itll run at idle then when i rev up the rpms and let off it dies after i let off the throttle
Brandon Hall my 2001 325i is doing the same thing did you ever figure out why?
@@brandonfarnham1110 yes i did come to find out i had a bad crank sensor to start followed by needing to replace the old fuel pump that wasnt working
that's an AFM, not MAF right?
Sorry for being pedantic but i just have to say that it’s not a MAF it’s an AFM Air flow meter on your car 👍 The MAF is fitted to the later 318is engines not this one. Sorry 😐
crashtestdummy27 no problem man I don't always use the proper term for every part, as long as everyone understands what I'm referring to in happy.
can you locate knock sensor 95 e36 318i ? thank
I have changed them before on a 318i, they are on the drivers side of the engine underneath the lower intake manifold.
E36 Fanatics it only one right?. And it single not duel sensor. Do you have part number ? Thank man
@@MrHengDoItAll No, there are two sensors on the 95 318i. On the OBD2s it is a single wire with two sensors, but there are two separate sensors on the OBD1 318i.
Ill take a look to see if I have the OEM number.
Can you help ? i changed Plugs,Cleaned and Swapped the MAF from a different E36,Cleaned the ICV, and i cleaned the Throttle Body, yet its still running like shit on idle. when i unplug the MAF everything is fine after a couple of seconds.
Any codes at all? Are you sure the maf was good from the other one? You have vacuum lines underneath the intake that get cracked as well.
E36 Fanatics the maf from the other car worked without any issues on my friends car. ill check the lines tomorrow once more. no codes since i dont have a reader and im on a Tight budget. thank you!
Styler144 if it does have a check light you can bring it to an auto parts store and they will check it for you, if it's pre 96 you check the code by pumping the brake pedal twice if I recall correctly
E36 Fanatics mine is Oct 96 and the check engine is off. i also have a video on my Channel. it idles very bad but doesnt stall. i will check all lines and hoses and report back to you if you dont mind
@@Styler_144 have you found out anything?
My 318ti starts and runs for like 5 to 6 seconds then dies. I have to start it and let it die like 10 times untill the air pump kicks on then it runs fine. Only happen when it's below 40 out. It's 97 with m44. Any ideas?
Will it hold an idle if you keep your foot on the gas?
E36 Fanatics. If if I give it a little bit of gas to hold an idle it will die the same way but if I rev it past 4k it will stay on. Cel says cam sensor but it has always said that
graeme petteway if you can keep it alive by holding the gas I bet the icv isn't opening properly, happened to my brother's car.
@@e36fanatics29 If the throttle doesn't work what is the problem likely to be starts then stalls like in the video?

So.. what did it turn out to be?
idle control valve, it was clogged.. Soaked it in carb cleaner for a night, and it's been running great ever since.
Thanks! Just removed mine and cleaned it really well as it was really filthy. Can't wait to install it tomorrow
Awesome! It certainly makes a difference.
I finally got rid of the rough idle! I cleaned the throttle body which was covered in carbon buildup from who knows how many years
That'll do it to! It sometimes sticks when all that gunk builds up inside.
What's the name of this engine
m42b18
👍
Ur video is short take a long one so I see how it ends with ur experiment please
