	Don, 1400-1600 rpm is *WAY* too fast for idle! I'd suspect your
idle enrichment is on all the time, or the mixture is mis-adjusted.
There is a third, more illusive problem, which I saw on a Rabbit. The
O2 Sensor is fail-deadly- on the waterpumper inline-four, a bad O2 sensor
will drive the K-Jetronic system to full-rich, which will eventually
cause the poor catalytic converter to melt, giving one a truely wierd
set of symptoms to troubleshoot.

	BTW, any excessive enrichment will have some effect on the cat,
if you have one- it tries to burn the extra gas.
