: HELP! I am a BMW rookie. Have owned the car for 60 days. 1989 535i E34. It recently started surging at idle and has even cut off on several occasions. Also it misses during hard acceleration to the point were you can see the drop on the tach. Are the problems related? Any ideas?
The ICV is humming. I removed it and cleaned the carbon build-up. It was pretty dirty. As soon as some of the snow melts and I can get out on the road I will see if that helped my problem.
