Hello,

I am having rough idle when I start my engine. The rpm starts at 1200 and turn to 1000 when warm. It doesn't go below 1000 until I turn off the engine for couple of minutes and then I start it again. At this time I start to see rpm around 800 to 900 which is normal. The question is why my rpm doesnt go lower than 1000 after starting and warming up and why it goes below after I restart my engine.
