I have a very low mileage (29k) 90 E30 that will sometime at idle bounce between 600 and 800 rpm. Goosing the throttle will usually stop it for a time. I just replaced plugs and air filter, no obvious leaks, or cracked boot. Also no codes or lights.
The biggest mystery is that it comes and goes. Drives fine otherwise.
Could it be a dirty ICV? I guess I will clean that next.
