In trouble shooting my intermitant high idle problem. The ICV seems to be working only part time and I want some confirmation before spending the ouch $500+ for a part. (It is a Euro version part no. 000 141 14 25.)

As the engine warms up it jumps to a higher 1500 RPM at idle. Discontecting the ICV does not change the RPM. Voltage with ICV disconnected while running is 13+ volts. Voltage with engine off is 11.7. Engine off and ignition on I can hear the ICV click when I unplug and plug it in again. Using a VOM on frequency setting, and connected to pins is irratic.

I decided to hot wire the ICV to battery and engine would stall, plugged the ICV again and the idle dropped to normal and I can feel the ICV pulsing or modulating, which it didn't before. Now I unplug and the idle jumps up again as I would suspect and normal when plugged in. The VOM freqency now runs about 59%.

Seems like a sticking ICV to me. I cleaned this valve before, but was a little ginger is doing so and might try again concerned about getting too soaked.

Appreciate any comments.
