Intermittent Erratic engine idling - hashie
My BMW328 has been suffering from erratic engine idle & then stall as well as power surge. Unfortunately it is an intermittent problem. It has been in to the dealer & they have replaced the throttle sensor, air mass sensor & cyclone valve and engine vent pipe. The problem is still there. It will be going back to the garage again this week. Does anyone have an idea of what could be causing this.
