I have a 1997 328is that has been stalling or coming close to stalling when I come to a stop light or sign. I thought at first that it may be a vacuum leak, so I changed all of the vacuum lines and hoses. Nope. I still have a problem. So, I proceded to change the following parts without any effect on my stalling symtems;
Mass Air Flow Meter (MAF)
Idle Air Control Valve (ICV)
Throttle Position Sensor (TPS)
Intake Boot
Spark Plugs
TCC Lock-up Solenoid inside the auto trans
Tranny Filter
Tranny Fluid
What's left? What could my problem be? I'm at my witts end.
When I scan the ECU I get absolutely NO error codes. None!!!!
Anyone out there have this problem? If so, what was the fix???
Please help!!!!

the most common running problem on the obdII cars is the cyclonic valve on the bottom of the intake has blown, it's the horible modern bmw design of a pcv valve that every bimmer after 96 comes with, it has a diaphram in it that splits and makes a huge vacuum leak, the easy test is spray around it with carb cleaner and see if the idle is effected, i find it hard to beleave it's not kicking up any codes as the obdII cars are overly sensitive to stuff that doesn't even make it run bad
all america wants is cold beer warm cat and a place to take a poop with a door on it
