Try the idle control Valve

@isaiasmolina2393 Жыл бұрын

Check lower intake boot for any crack mine did th same and it was the lower intake boot. Unfortunately I didn’t realize on time and this ended up killing my throttle body 😢

If you haven’t already I’d rebuild your vanos. It’s simple cheap and easy

Did you check pipe from holes that goes from valve cover 2 air?

I have the same problem but mine just dies after 10 seconds running like this. I disconnected the maf sensor and it was way better. So i just replaced the maf sensor itself but it was still running rough just like the old sensor. Could it be a vaccuum leak?

Mass airflow sensor is bad probably try unpluging it and it should fix the problem!

I had the same problem, and your solution was worked halfly. But not perfectly. And now it did like 2000rpm it shakes. Any idea for this?

@kelpsakipras84 Жыл бұрын

@@BelvariAndras Idk man if it shakes it could be the engine holder bushings and for the revs probably the intake or electricity i dont have a concrete answer to this

i have the same car with the same problem but mine drop when i rev it till 1200 rpm then it goes down to 500 rpm and come back to it normal place . the problem gets worse after hard acceleration and long trips so i think that both of us has to change the fuel pump ive checked everything and still have this problem so now im sure that i have a bad fuel pump

GNB bh Hi bro, did you check compression ? my problem is gasket head, or just head.

@northernmaten7676 6 жыл бұрын

hey no i didnt check the compression but mine is not as bad as yours its running great and it has the power but my problem is that rpm on idle after revving it till 1200 rpm so maybe its vaccum leak or bad fuel pump cz i still have the original one and im sure the problem is not the head gasket or the head 2 years ago i changed the head gasket and polished the head it was like new

btw what is the noise in the video that clunk is from the engine?

@dragnetpro917 6 жыл бұрын

GNB bh I use LPG in my car, and its same on petrol or gas, so i think fuel pump is not my problem. What was symptoms when you change head ? hmm mine is also have power but everybody tell me that is a problem. And this noise is from rain and bad road, not from engine.

Hello there!!! Did you find the problem? My car has the same problem as yours. I changed the same parts as you and did all the same procedures that you did. I have been battling this problem for 1 year now and I still have nothing. Today looking for the problem on the internet I find your video and I am glad to know that I am not the only one with that problem, because in my city no one could help me, and on the internet there is not much about this either. I do not know what else to do. Other things I did in case they help you, was to check bugs from BMW SCANNER and INPA, but I did not get results either. I wait your answer. Greetings from Argentina.

@@bignae8845 not yet, there are 3 things that I didnt do, clean inyectors, remap ECU and remap throttle response. I suspect that the problem is the map of ECU/throttle because doesnt have logic.

You said you changed your maf and lower intake boot assuming it had cracks and didn't fix the issue my assumption is a damaged throttle body as you may have took to long to fix the issue

i dont think so :/ antifreeze in oil? and i have some issue on neutral, but not so much. maybe vacuum leak, but i checked by a smokemachine and nothing

sokolxxlservice Until now i change DISA, CVV, Lambda Sonde, Oil Separator, but still nothing helps. I also try smoke test, but can nit find any leaks. I think i dont have antifreeze in oil or oil in antifreeze. But i have big pressure. A few months ago, a bottle of collant was exploded. 5 days ago my expansion tank bleeder screw was explode also. Do you also have problem whit fuel consumption needle ?
