Thanks, guys. Even disconnected, the problem is that it sticks at closed or at just about 1/8" open. It is probably stuck closed since the car will not stay running. Previously, it was probably stuck at the 1/8" open and would run after warming up a bit. I'm just going to get another one. There are used ones on eBay for $40-70. The new ones are $200+. I may try a used one--since I'm a cheapskate.
