[QUOTE="crash2, post: 1009029, member: 15940"] Ok--so since I got most of the air out of the system--I ran the engine hot and kept the cooling fan off--unfortunatly I forgot my laser temp reader so I had to go by feel. So I let the guage get above the middle and turned on the fan. I kept feeling the return line near the motor--and I could feel the tube getting cooler.. So now that I was able to have the rig run for any length of time I decided to start taking care of a few things. The first thing was the idle did not drop--stayed around 1200rpm's. So I checked the voltages at the idle control soloniod and the voltages seemed correct(or what I thought judging by the info I had). So I unplugged the soloniod and the idle speed did not change any. So at this point I figured it was time to remove the soloniod and inspect it since when we got the motor there was some signs of moisture in the throttle body. So I pulled it off and here is what I found inside the soloniod. [IMG]http://rdsd.com/albums/album13/jack414.jpg[/IMG] Yup--there was moisture inside it at one time. Now I have never messed with this particular style and origionally thought there was a pintle that went in and out. [IMG]http://rdsd.com/albums/album13/jack415.jpg[/IMG] After some playing with it--I found it actually rotates like 20 degrees.
