E30 Surging Idle When Warm, This weekend is half off at the junkyard and we're picking up spares of just about everything mechanical. And since the youngest E30 is going on 20 years old, if the ignition system is original or the plugs are old replacement is indicated. Often it surges between 1000 - 1500 RPM, but sometimes it can just get stuck at around a I've fitted a new air flow meter and cleaned the idle Air control valve which seemed to sort it at first but only took a short drive and didn't allow time to warm up. It runs fine off idle with no apparent loss of power, however intermittently it will not idle at the correct RPM. And that's why I'm even looking to fix this "vacuum leak". It idles between 500-850.
