    My 205 has a 1.9 Mi16 running with the Motronic setup. For a while now the idle when cold has gone very high, often around 2.5-3k. When warm it does drop down, but rarely to a nice steady 900rpm, often around 1.2k. To try and give some clues I've just run the engine when cold: - Without touching anything it idles around 3k. - If I disconnect the idle control valve electric supply the idle drops a bit to around 2k. - If I have the idle control value supply reconnected, but clamp shut the hose feeding it, the idle drops right down to below 1k and pretty much stalls (obviously still cold, so wants some more revs). Does this suggest an idle control valve problem, or something else? The throttle switch clicks, but I haven't had the chance to test it's connectivity. The temperature sensor seems to read sensible resistance values.
