Gents,
When my car is warmed up driving around; I put my car in neutral and coast it will rev to 1500 rpms. Once I come to a complete stop, it will continue to stay at 1500 rpms for about 8 secs than drop to normal RPMs.
My car has already been dyno tuned using a wideband, so I don't want to mess that up. Other than that issue, it idle perfect, starts up warm and cold perfect...just this one annoying issue. Its an LS6 with a 228R cam / 5 speed manual tranny.
Here is a video
