I did a bit of searching but did not have much luck looking for answers.
My car is a 95 325is, and has a serious idle problem in the cold. It will idle very erratically jumping around the rpm's. It idles fine in warm weather or in any temps over 40 degrees. I have now checked the resistance in coils, the throttle position sensor, as well as the fuel pressure, all of which seem to be fine. I have also put in new coolant temp sensor, crancase vent valve, and throttle body gasket.
I previously cleaned my idle control valve and the problem did not go away. I then put in a different idle control valve, one that came off a 93 325. Today I got the actual Bentley specs for the resistance in the ICV which is 20,20,and 40 +/- 5 Ohms across the terminals. I measured the current and my original ICV both of which had resistances of 12,12,and 23 Ohms. Is this normal? Does anyone else have resistances from their own cars? Any idea what the problem could be?
