I removed the idle control valve to clean it and found the following:
* the hose from the air intake to the valve had a 2" split
* after cleaning the idle valve, I noticed that the de-energized valve only opened about 1/8". When applying power, it might close or not. When de-energized again, it might open to 1/8" or it might stay shut. A little prodding with a screwdrive ands it would open, but just a bit.

I replaced the hose and put the idle valve back in (no spare). Now, it will not idle at all by itself even after warming up a bit. If you take your foot off, the engine will stop.

Does the idle control valve open further than an 1/8"? It also seems to stick. I will plan on getting a replacement if I can find one. Any comments out there with idle control valve experience?

Thanks.
