not really. from what i understand, Porsche 911s (at least the 964s and 993s) do the same thing when you use a light flywheel. however, i also understand that some people solve the problem by tuning or fooling the computer into thinking the A/C is on all the time. i guess that roughly equates to raising the idle, like you said.
