This happens to mine too. It over revs to 1,200 rpm when the car is stationary. I took it to the dealer and they plugged it in, but no fault found. Their explanation was "Most IS 2.2d over rev depending on the temp of the catalytic converter". I have no idea if this is true but sounded plausible.

Hi All I'm not sure if this has been covered in any other forum but I'll ask the question anyway. I've only had my IS2.2 SE (06 plate) for 2 months and last week I took it back to the dealer with a few problems to fix. Needless to say I wasn't too sure if they were just giving me a fob off and telling me everything was normal just to get me out of the dealership. My problem is, my engine idles high, around 1,200 rpm. I gathered as much info for the dealer but they just told me it was normal. I've listed the conditions below. If anybody knows what's wrong please help. 1. At start up the engine idles at 1,200 rpm outside temp 15c 2. When driving for 10 minutes and the engine is at operating temp it still idles at 1,200 rpm 3. At speed I put the car into neutral and it idles at 800 rpm but when I stop at traffic lights (slowing down in neutral) and come to a stop, within 2 seconds the engine returns to 1,200 rpm 4. All Air con, radio etc.... are turned off so no extra demand on the engine. Please help, I have no idea why this should be acing this way and I'm sure it doesn't help the mpg.
