this probably wont help but let me tell you how my R acts...

if i havent started it in like a day or a few hours in the cold.... when i start it, the idle is around 1400 or so and slowly drops as the car is warming up i would assume. At 1400 the whole car kinda vibrates a tad, enough that i can feel it thru the seat. The vibrating goes away as idle drops. My idle will stay around 800 or so once the car has been fully warmed up. If i go ape shit and do a nasty highway vtec run for a long period of time and then hit an offramp and stop at the end of the ramp....the car will be idling at around 1200 or so and then drop down to like 500 after like a few seconds and then come back up to 800 again and stay there. I would assume this is normal behavior, my GSR acts about the same, but im not sure...... if anyone else knows anything else, about either his car or mine, say so,
