Just bought this 92 325i and it idles rough when the car is cold and then sometimes at a stop. The seller told me it was a vacuum leak. He said to get the Idle Air Control Valve hoses (2) and that would fix the problem.
The check engine light is on as well, Im going to VatoZone shortly to see why it on.

These early 325 engines have a lopey or irregular idle, even when warm. I took the electrical connecor off of the Idle control valve, took all hoses off and sprayed contact cleaner in the electrical connector area and throttle body cleaner into the valve itself. I put it all back together and it works fine (still has the irregular idle). As to check engine light, at first start ,the lght is on until you step on the brake pedal, then the light should go off.

the vacuum leaks are hard to track down...theres a billion hoses underneath the intake manifold. the other possible problem could be your idle control valve. and your idle will still be rougher than other 325's simply because the 92's had hotter cams then other M50 motors because they lacked the variable cam timing that other m50 motors came with.
