My mechanic wants the car on Friday. He thinks the thermostat is sticking, and since we have never replaced or flushed he wants to do that. After seeing some of the other posts, this probably won't fix the "problem" as it might just be the way it is. I'll be putting a 195 back in. We'll see Friday night if anything changes.

Well, the priliminary results are good. I have yet to drive it home, but what little I did drive this noon looks promising. The "base line" sits a little below 200 (or a little left of straight up), and swings a little above 200. Will know more tonite after the drive home.
