Maybe I didn’t read closely enough, but does the temp also rise while coasting fast down a long hill in neutral while idling?

But it rises when engine is idling and car is not in year. Also I get a little over 28 mpg when I Coastin mutual verses 26 MPG.

If you are coasting in gear, the injectors are shut off and no fuel is consumed. If you are coasting in neutral, the engine is idling, and you are burning fuel. The difference is how much engine drag is caused and does it prevent you from maintaining speed. Shutting off engine as you coast in neutral is a really bad idea as also lose your source of vacuum for braking.

But it does save on gas on just about any car. Corky has done extensive testing and can stretch an extra 1-4 miles per gallon by doing so. It’s strange, but he finds this as a personal challenge in any car he drives.

Why would you put it in neutral on a downhill highway? Its an unsafe practice and does not save gas. Based on that, its a circulation issue. Water pump is suspect....

So if I'm going downhill on the highway and slip into neutral I will see the gauge start to go up. It heads straight toward the top and rather quickly.

If you are cruising at 60 and take your foot off, does it get hot? Or do you mean it overheats any time you stop, rather than any time you take your foot off the gas?

Thanks for the responses. Both fans work. Water pump is new. I blew the head when I over revved the engine after getting stuck in a ditch in October. There are no leaks. Coolant level has remained steady since the repair. Sent from my iPhone On Jun 7, 2012, at 11:36 PM, Joey Delgado <[email protected]> wrote: Having strange heating issue suddenly. After long drives on the highway and ONLY when I take my foot off the gas, the gauge shoots up. So I go on a long drive, pull off the highway and sit at a light and it starts heading toward the top pretty quickly. Step on the gas to go at any speed in any gear and it drops back to normal. Is this a bad thermostat or something else? Background - This is a 96 Miata. I blew the head and had it replaced by a friend who's a mechanic. Works pretty fine except the engine is a little loud and now this heating issue. Suggestions? Thoughts? Thanks in advance!
