my car, which i drive almost daily, has run flawlessly for several months. then yesterday it did something strange: after sitting for a couple hours, it started fine but idled very roughly - and when given any gas, it missed, coughed, and almost stalled - in short, not driveable. i then noticed a clicking/arching sound coming from my ecu (motronic 1.3, bosch xx179 with miller war chip) that corresponded with the cutting out/stalling of the motor - it was as if the motor was momentarily shut down corresponding to the 'click' coming from the ecu. and the click was pretty loud as i heard it over the running motor and ecu inside the closed glove box. i shut it all down, then after restart all ran normally.
any ideas??
