Hi Again:
You know, I thought about your problem since I emailed you earlier. The more I think about it, the more I want to say readjust the PS belt. It may be a seperate belt from the serp on your van. Or, if it's a 3.8L it may not have a seperate belt. It's sounds like at a low RPM it the pulley may be sliping causing you touble. Also, make sure that the self adjuster is keeping enough tension on the belt. Let me know if it has the seperate belt. Also, let me know if this helps. Finally, if the belt has 50K on it, it's most likely due for replacement. The belt companies recommend if you have more than 3 cracks within an inch, it's due for replacement.
Let me know what you find.
Joe
