Hi all E30 enthusiasts. I bought an E30 cabriolet 318i (M40 motor) which iv been trying fix myself. The problem is that the idling serges and Iv replaced nearly everything pertaining to this problem...Air leaks,airflow meter, ICV, ICS, hoses, but it still does the same thing. Iv even had my timing done. Iv notice that when I plug in the ICV then rev needle goes up to 3000rpm (when the ignition is on) this happens even when I use a test light on the ICV plug. I feel that this is the reason for the serge, but how to fix this, I have not the slightest idea. Any help would be very much appreciated. Thanx Guys
