seems to hunt when warm, but idles far too high straight away. its now getting worse with the colder weather, was hunting to 3.5k in a queue in other day, sounded like it was bouncing off the launch control every 2/3 seconds

looked like a right tit (nothing new there).
the Hondata says its programmed for about 1.5k on cold and around 0.8 on warm, but changing that has no affect - checked the throttle cable as well and that seems set up ok, not set too tight or too high.
going to swap the tb for a spare and finally re-do the coolant tonight hopefully.
