car wouldnt stay running...?

i just bought a 98 328i with 167,xxx miles, and i was gettin ready to leave for work and it woldnt stay running, it would start but then it would die instantly... it was odd b/c i had to move the car like 20 min earlier so my wife could get outa the driveway... i took apart most of the intake to see if maybe it had something to do with it, everything looked fine... so i started the car and gave it some gas so keep it running... i did that for about 20 seconds or so. then the car ran fine... i assumed it was something with the fuel system like bad injectors or something. then as i was driving to work i noticed the check engine light was on... when i was stopped at a red light i turned the car on and off, then after 4 times the light turned off..

has this happend to anyone else? and is this a common issues with these cars? also what is most likely the cause of this? i kno these cars are prone to having issues with the air intake and i think with the idle control valve.. any suggestions?

Should have left the check engine light on. If it does this agian and the light comes on, put a scanner on it.

Did any white smoke come out of the exhaust when it was having a hard time idling/running?

I'm thinking that white smoke is usually indicative of coolant in the combustion chamber as in blown head gasket (if its continuous cloud). If it's only at startup it might be worn seals so you'll get a little bit of leakdown. Hopefully someone will correct me if i'm wrong

In most cases yes, but I had a similar problem a few weeks back when my CCV completely collapsed. Not only could my car barely idle but I had some white smoke coming out of the back. CCV's are a common annoyance on some BMW engines because not only do they freeze during the winter (like mine used to) but they sometime won't open and essentially chokes the engine to death (not literally though). I've had my car physically stall at a red light when it was almost 0 degress F last winter and it idled erratically beforehand. No coolant leakage BTW.

It's possible, your problem sounds similar to mine but it's not gauranteed to be the same thing. Before anything else I think giving the MAF sensor and ICV before changing anything else might be a good place to start. When the idle control valve get dirty on these cars it can cause erratic idling and stalling as well. Cleaning the MAF will allow the sensor to read more accurately. If these don't work then you can start looking elsewhere.

I suggested the CCV first because your problem sounded suspiciously like mine a few weeks back. The CCV is normally mounted on the intake manifold somewhere, usually near the rear of the engine.

Sounds like the PCV to me too, common part to fail, and the symptoms you have ......white smoke on start up is an indication.

Not 100% sure but I think its #19 here:
