My 740 (1990, B230E, non-turbo) has been running rough at low rpm. Once above 1800 rpm or so it's fine. I've changed the Distributor cap and rotor arm (they were both shot), but the problem persists. I'm thinking injector relay or ignition stage amplifier next, but I don't want to just through parts at it. Testable hypothesis are welcome!

FYI: the plugs were changed 3 months/1,500 miles ago. The misfire is intermittent.

clean your throttle body at the butterfly with throttle cleaner, and your idle control valve.
