I have a problem with the Idle that I can not diagnos. This car has a carberator, when starting the car cold, the Fast Idle kicks in (around 2000 RPM's), then kicks down to about 1000 RPM's, which should be correct, but after the car warms up and driven for a while the Idle drasticaly drops. When stopped at a light the idle drops all the way down to 100 - 200 RPMs, almost dying. Can anyone point me in the right direction?
