Hello,

I have a 1992 325i that ran fine until about 4 months ago. The car started dying at idle, when it is moving I have no problem. It has no pattern sometimes it idles ok but still just a little rough. So I decided to take the car to a dealership. First they replaced the plugs and promised this would fix my problem, but it did not. Then I took it back and they replaced my ICV, I didn't even make it out of the parking lot before it died again. Next they told me it was the MAF (Mass Air Flow Sensor). I found one on e-bay (used) for a fraction of the price and it still didn't fix the problem. I DONT KNOW WHAT ELSE TO DO! Could it be the oxygen sensor? PLEASE HELP!!!

Thanks!

the dealership miss-diagnosed the car and didnt fix the problem? damn i would have lost it on them. usually i would have said MAF but if you got that covered. do me a favor. check the intake elbow. on the bottom should be i think two air tubes. make sure they are on nice and snug. (im really not sure if its two because i have a 6cly)

now if that seem clear. take off the intake elbow and check for blockage in one of the tubes.

thats a start, i cant think of anything else right now. all i can say is take it back to the dealership and complain.

good luck and welcome to BWM-forums.

It could also be a vacuum leak around the intake manifold. Either the gasket or the intake itself could be cracked. If that is the case it would do it all the time. I had a similar problem but mine would surge up and down at idle only when warm or at normal operating temps. Turns out it was my Mass Air Flow Sensor.
