I have a question about the Type-R Tach and Idle. I have a 2000 ITR with 38K miles on it. I have all my major maintenance done at the dealer and use the car as a daily driver. I haven't taken it too the track, yet, and only drive it hard occasionally. I bought the car used with about 13K miles on it from the first owner who drove it pretty hard and took it out to the track once in a while. My performance mods include an AEM CAI but it cracked so I cut it to make it into a short ram and a Tein or is it Tien coilovers. My questions is the idle on the car is usually is at about 700 rpms and sometime fluctuates to about 1100-1200 rpms after the car is warm. Is this something that is normal? If not is it or will it damage my engine? I took it to the dealer and they said this is normal and nothing to worry about? Any info or advice from you guys is greatly appreciated.

Thanks.....
