I just replaced my belt that drives the alternator , power steering, and the water pump. As well, I replaced the water pump and the fan blade i did remove the air intake during this for easier access. Now I have everything put back together and the check engine light is on at low rps also when you try to take off and let the clutch out the engine cuts out. Unless you give it higher rpms. the check engine light also goes off when you give it higher rpms.
I had a friend helping me and when he was taking the in take out he busted a nipple. I epoxied it back together but in fear of breaking it again I didn't tighten the hose clamp as tight as I normally would its lightly snugged if you know what I mean...PLEASE HELP ?

Could very well be a vacuum leak right there (would really only matter if it was after the MAF though).

btw, What model is this on; might help us diagnose a little better.

oops ya it might ...It is a 94 325i ran perfect before i broke a belt

sburton · 10-23-2009, 08:42 PM

what is the MAF if you dont mind me asking

Torque · 10-23-2009, 08:53 PM

Air flow meter/sensor. It's on the intake piping. http://data.bmrparts.com/qimages/p/8260025065837U_1.jpg

If that nipple is after it (meaning closer to the intake manifold), then a vacuum leak due to a broken nipple could make a difference.

Btw, what I suggest you do since you get a check engine light is to do a 'stomp test' and get the code and see what the code is for. I'm having a hard time attaching the e36 service manual, but if you go to the 5 series subforum and download the Bentley manual that's pinned to the top of the forum, that has the procudure contained (under Engine > Driveability troubleshooting): it's exactly the same.

Actually, here you go, http://www.bimmerwerkz.com/forum/3-s...pdf-67601.html

this is definitely better then the Chiltons manual I picked up. Not to be lazy but where or what chapter do I go to to do a stomp test . please excuse my ignorance but I have no idea of what a stomp test is

sburton · 10-23-2009, 09:59 PM

Oh My God This manual is so much simpler than what I have. Again I thank you

Torque · 10-23-2009, 10:06 PM

On the left sidebar hit Engine, then scroll down to Driveability troubleshooting.

thanks again it just finished downloading i was lookiig it over and you said it perfectly it is alot more comprehensive than anything I've seen

Torque · 10-23-2009, 10:21 PM

Let us know what code(s) you get; also look over the belt replacement procedure and make sure you didn't forget to reconnect something.

sburton · 10-23-2009, 10:21 PM

Thanks for pointing me in the right direction.
I'll keep my eye on this thread as you suggested I am learning alot about this german engineering. The performance of these cars could tur anyone into a BMW lover no matter how complex the engineering is

sburton · 10-23-2009, 10:23 PM

OK will do tomorrow and ill post thanks again

Torque · 10-23-2009, 10:24 PM

You're welcome; that's what I'm here for. hah

sburton · 10-23-2009, 10:24 PM

obviously I meant to say German engineering earlier. I hope my typing didn't insult anyone
